Snowfighting

(Click on photos for a larger view)

Maintenance of Way (MOW) is hard (and sometimes dangerous) work.  Add to it the harsh, unforgiving Alaskan winters and you have a chaotic situation that can bring operations to a standstill. Typical winter challenges for the Alaska Railroad are:
  • deep snows (sometimes can be in excess of 10 to 15 feet)
  • avalanches, snow slides (snow, mud and rock)
  • ice buildup on the rails and switch points
  • frost heaves bend or buckle the rails 
  • moose on tracks (Moose will use plowed rail areas to conserve energy or escape wolf packs.  During Alaska's worst year (1989-1990), 749 moose were killed by the railroad.  Sometimes a snow cat is used to make side trails from the tracks so moose have an escape route.  For more information see Moose and the Alaska Railroad.)
  • Keeping extremely cold temperatures and ice from affecting locomotive mechanical systems
  • Snow slide

    Over the history of the Alaska Railroad, a wide variety of snow removal equipment and techniques were used:
  • hand tools and explosives until 1935 
  • bulldozers and steam shovels
  • snowplows in 1928
  • snowsheds
  • Russell plow
  • Jordan Spreader
  • rotary
  • recoilless rifle
  • ballast regulators
  • plows
  • jet blowers
  • switches
  • Shovels

    Snow and ice problems vary depending on the geographic location of the railroad.  Some of the worst areas of the Alaska Railroad are:

  • Through Kenai Peninsula - mountains have snow 10-15 feet deep
  • 50 mile stretch along Turnagain arm - avalanches and ice buildup
  • From Anchorage to Canyon - 2-5 feet of snow, temperatures down to -50 degrees, big snow drifts due to heavy winds

  • Snow Removal Equipment
     

    Wedge Plows
    Although the Alaska Railroad never used wedge plows, for sake of completeness, they are mentioned here.  The wedge plow was basically a big wooden box, riding on freight trucks, and fitted with a large, wedge shaped front.  Three to six engines were coupled behind the plow.  The train would get a running start to drive the plow into the drifts, pushing snow up and away from the tracks.  While this design was quite & effective and widely copied, it created huge walls of hard packed snow next to the right-of-way.  The next storm would fill in the plowed sections, and the walls made it impossible to move the snow away from the rail.  The wedge plow also did nothing to remove snow and ice from between the rails, which had to done to prevent derailments.  Another machine, called a flanger, was developed.  This was basically a car equipped with a large-shaped mold board.  This rode the edges of the rails, breaking loose accumulations of snow and ice.  An operator had to ride the car, raising and lowering the flanger wherever there was an obstruction in the rails.

    Jordan Spreaders
    Jordan SpreaderThe Alaska Railroad's Jordan Spreaders (numbers 5, 6, 7 and 8) were built by the O.F. Jordan Company in 1929.  These units are large, elaborate pieces of equipment with a high glassed-in cab for visibility, a wedge front and wings at the side which can push snow well off the tracks (see mechanical drawing for further information).  Spreaders are the largest pieces of snow removal equipment to see frequent service.  They carry their own footnotes in timetables concerning maximum speeds, handling procedures and other restrictions.  When facing the task of serious snow removal on the Alaska Railroad, the Spreader will use several locomotives to push it.

    The spreader is also used by MOW crews to spread ballast along the track using the folding, hydraulically adjusted wings on either side.  Spreaders have spanned the steam and diesel era, serving the nation for decades.

    From Frank Dewey, Alaska Railroad locomotive engineer and veteran snowfighter (12/22/99): "The Jordan Spreader was the first "all season, all purpose tool", may be compared with the "Swiss Army Knife". It can slice, it can dice.

    "They were first operated by pneumatic power as air pressure could be supplied indefinitely by the "pusher locomotive". As with most modern heavy equipment they were much later equipped with hydraulic power.

    "Spreaders are most often operated in snow service with two pusher locomotives for better traction.

    "Spreaders are now usually replaced for all but the heaviest snows by "ballast regulators" (see ballast regulators)

    "Crews for "Snow Fleets" usually consist of:

  • Roadmaster familiar with all the characteristics of the territory
  • Heavy Equipment operator
  • Conductor, who usually operates the "nose" plow
  • Engineer (to really be the guy behind it all)
  • Brakeman to clean switches and relieve the conductor on the "nose".

  • Crews are governed by the "Hours of Service Law" so may only work 12 hours at a time. Engineering personnel are not and may operated many more hours as needed (see ballast regulators)

    Note: information on Jordan spreaders 1, 2, 3 and 4 is currently unknown.

    "Spreaders #5 and #6: Retired about 1974-76 (one of them in Transportation museum in Wasilla) older style narrow cramped, wet and drafty cab.  Crews liked them because they could wing faster and the pneumatic cylinders reacted much faster, but you had to know what you were doing.

    Jordan #7"Spreader #7: The winter spreader" was built in the early 70s to replace spreader #5.  Number 7 has a full length house along deck which makes it top heavy, so it rocks and rolls at critical speeds. After a roll-over derailment with the 3008 and the 1808? at MP 139 (1994?), it was rebuilt with four window GP40 style side windows and a propane heater replacing the oil fired stove. The propane stove requires four tanks to be mounted on the sides; kinda looks like bombs hanging there.

    "Spreader #8: The summer spreader" was built about 1976 to replace spreader #6.  Rarely used in wintertime, if used mostly on the "south end" with ice cutting edges installed on the front plow. Mostly used for summer ballast work because of better visibility.

    "Spreader #9: Built for the Alaska Railroad in 2000."

    From Bruce Gough, Alaska Railroad section foreman (12/29/03): "I took the spreader #9 from Portage to Seward on 12-23-03. Two to three feet of snow had our tracks buried and the spreader 9 did a good job of handling the white stuff. I took one photo out the window at Hunter. Pictures are not the greatest since was taken in other than ideal lighting with a digital camera."

    Russell Plow
    Railroads were always seeking more economical ways to fight snow, so it wasn't long before all three designs were combined into one car.  By the early 1900's, the Russell Car and Snow Plow Company of Ridgeway, Pennsylvania, was a leading supplier of wedge-type plows.  The design had been modernized with a cupola and seats for an operator, headlight for night operations and a pair of air-activated side wings to push snow up and away from the side of the tracks. Wooden bodies were still common, but within a few years, all-steel plows had proven to be more durable.  Both single track (as depicted by this model) and double track (which had one side of the blade enclosed to prevent snow from being pushed on to an adjacent track) were offered.  Russell continued supplying steel plows to virtually every railroad that fought snow until early 1950's.

    Russell PlowSince they only see seasonal use, which varies according to the severity of the winter, and were built tough, many of these veteran snow-fighters are still in service.  Often the only modifications have been a conversion to diesel-type headlights, installation of radios and the addition of an MU plug at the back to provide electrical power.  Air for the wings and brakes is supplied by the locomotive, and some roads have equipped engines for plow service.

    In operations, plows are run as extra trains, but usually have rights over all other trains on the line, because of their important mission.  If things are bad enough, they may be the only trains moving at all!  Weather and track condition reports are made by area trains crews, and the plows are will be ordered by the chief dispatcher when conditions warrant.  The crews are well trained and include the plow operator, the division roadmaster (who knows the geography and track conditions firsthand), and the engine crew.  Usually several crews are trained to provide relief if conditions persist.  In the steam era, a camp car with a gang of workers and a tool car carrying shovels and repair parts, often accompanied the plow.  If the plow became stuck or the drift was too deep, the crew would shovel away the snow by hand until the plow could handle the job.  Today, construction equipment will be brought in to clear the line if the plows can't handle it.  (Information courtesy of Walthers)

    From Frank Dewey, ARR locomotive engineer (12/22/99): Never really used, it was put to pasture nearly as soon as it arrived. It seems that the ARR received it new from US "postwar stocks". Russell plows were very successful in the eastern and plain states at removing snow drifts. The ARR does drift in only a few areas, such as from Broad Pass to Summit, but the plows mounted on the locomotives work just fine for most of it.

    "The snow on the plains and in the east drifts from large open areas and fields in the cuts that the railroads right-of-way ran through, creating very long and hard snowdrifts. The push plows like the Russell work just fine as they are "rammed" into the drift time and again until they break through.

    "Here in Alaska we experience less drifting and we have many curves. It seems that they operated the Russell only a few times before becoming frustrated with it always de-railing on curves. The Russell and the SD70MACs have something in common. The distance from the front-center point of the plow to the bolster is far enough to cause the plow want to travel in a straight line, thereby pulling what is behind off the rail."

    From John Henderson (7/14/00): The ARR had a pair of wooden Russels and then a pair of steel ones.  In the late sixties I had the opportunity to talk to the Chief Mechanical Officer of the ARR and asked about the steel Russels. When I did I got the following story from the fellow, a former employee of the Bangor & Aroostock RR.

    In the mid sixties the ARR had "one of those Winters" when the CATS, Jordans, and even the ROTARIES couldn't keep the railroad open.  The CMO asked why they weren't using the Russels and got a reply something to the effect that, "They don't work!!!!"  Research found that an employee had been killed in one of the wooden ones when it hit a slide filled with trees.

    The CMO ordered the # 4 Russel brought in to the shops and made road worthy (glass replaced, wipers working, etc.).  The CMO then asked for a volunteer train crew to push the Russel with him operating it over the railroad.  He got it IF the crew was permitted to remain in the REAR UNIT of the four F units assigned to the plow train.

    The conclusion of the story I heard was that the plow train headed out of Anchorage for Seward and got to FAIRBANKS within the 16 hour "hours of service" rule.  I don't really believe that time line but I do believe the general content of the story.  It matches photos I have of a derelict and serviceable Russell # 4.

    Rotary Plow
    Rotary 1918-1930Rotary plows, developed in 1883 by Orange Jull and marketed by the Leslie Brothers, are the largest of pieces of railroad snowfighting equipment. These behemoths can throw snow hundreds of feet from the tracks and can clear a swath through a dozen or more feet of snow. Due to operating expenses, however, they rarely see service. A measure of their importance can be seen in the fact that Union Pacific and BNSF each have no fewer than 10 rotaries available. Today most rotaries are powered by electricity supplied from a trailing locomotive, a specially converted power car, or an internal diesel engine. Several steam powered rotaries survive, and a few are operable today.

    From Frank Dewey, ARR locomotive engineer (12/22/99): "The Alaska Railroad's rotary #3 was built by Cooke Locomotive Works, in April 1930 (see mechanical drawing for further information).  It was operated under steam well into the 1960s.  Converted by the ARR to electric operation with (2) EMD D-47 traction motors geared to the main drive shaft. Originally powered from a F7B unit that would have its main traction generator disconnected from its traction motors. Power cables would then be strung through the end door into the rotary and connected to terminals there. To ease the laborious procedure, the ARR had (3) 1800 locomotive converted to MU controlled power mates with the installation of (4) power receptacles under the front walkway, and a second MU plug on the front MU stand and a RSS switch in the electrical cabinet." Although totally operational, it was last used in 1995.

    Rotary blowingFrom Rick Leggett, ARR General Roadmaster (5/26/99): "I know it [rotary #3] was built for the CMStP&P (Milwaukee Road).  Our electrician Sam Lane tells me his father, a retired Milwaukee electrician himself, recognized it.  We last used it about 8 years ago, and that was the first time.  Ironically, Sam was hurt while readying it for service (caught his hand in a door, as I recall).  It was originally steam powered and was, I believe, a genuine Leslie plow.  The Milwaukee converted it to electric powered (generated on board the first loco behind it).  There is one feature of this plow that I find intriguing;  it is the only piece of railroad equipment I have ever been in with a balcony.  When one leaves the cab he steps out onto a platform from which a stairway descends to the machinery deck.  It sure looks like a balcony to me."

    From Dick Brown, Milwaukee Shop Electrician Apprentice (12/29/08): "The following comments come from my feeble memory of events while working at Milwaukee Shops of the Milwaukee Road as an Electrician Apprentice from 11-56 to 8-61. These comments are my personal recollection of the construction of a rotary plow that was built in the Milwaukee Shops sometime during my Apprenticeship on the Milwaukee Road. This may be the Plow Unit referred to in the web page, "SNOW FIGHTING ON THE ALASKA RAILROAD" by Mr. Rick Leggett. This information may augment the information presented in the Web Page referenced and are not intended to alter or supersede Mr. Leggett’s comments.)

    "I recall that one of the projects that I briefly worked on as an Electrician apprentice, was the construction of a rotary snow plow in the mid/late 50’s, however I can’t pin down the exact time frame.

    "I do recall the balcony or catwalk, mentioned in Web page referenced above. My recollection is that this consisted of a platform with hand rails and a ladder between the Operating Cab level and the floor level of the car body.

    "The entire fabricated steel body was new construction with the exception of the frame, trucks, and the rotary blade assembly which was salvaged from an old Steam Driven Rotary Plow. I suspect that the heavy duty frame and trucks may have been salvaged from a large steam locomotive tender. The Milwaukee Shops were very good at salvaging from old equipment to make something new. I also recall that the frame was a very large frame of heavy cast-iron construction. (side line – They also salvaged smaller steam locomotive tender frames to build several yard cabooses. This worked very well, the frames and trucks were heavy duty construction and stood up to the heavy switching duty on the Air Line Hump in Milwaukee. One of these Yard Cabooses survives today at the Trolley Museum in East Troy, Wisconsin.

    In the new design the rotary blade formerly driven by steam, was powered by four Diesel-Electric Locomotive traction motors. These drive motors for the rotary blade were arranged in the car body on both sides of a long, large diameter drive shaft that was located on the longitudinal center line of the plow frame. The traction motors were arranged alternately on each side of to drive the shaft with direct gearing similar to the motive gearing of the locomotives. These motors were powered from a Diesel-electric unit coupled directly behind the plow unit. The third unit of this consist was a Diesel-electric pusher. The pusher and the rotary blade were controlled by the Locomotive Engineer from the front of the Plow Cab via the existing train line control system. This system is common to all Diesel-electric locomotives to allow control of multiple Diesel Electric Units from the leading locomotive Cab."

    From Frank Dewey, ARR locomotive engineer, (12/22/99): "Rotary X-900212 (ex MILW) on display at Potter Section House (never numbered or operated by the Alaska Railroad) was purchased when the Milwaukee's "Western Lines" were shut-down in the 1970s. It was used in the Bitterroot Mountains of Idaho. ARRC engineer Steve Cain, a former MILW engineer, was one of the last Milwaukee engineers to operate it "under wire" out of Avery, Idaho. Proof still exists in the Catenary Platform on the rear roof section and that it is powered with a "Bi-polar" motor.

    "Rotary Snowplows are rarely used any more on the ARR as Caterpillar D-6s respond faster, can move snow much faster and need to only have one operator. The last time rotary #3 was used, was after a very heavy snow fall that plugged sidings during a heavy snow season in which the berms were too high and frozen to be moved by either cat or spreader. The rotary could throw the snow 300 feet over the berms, but in most conditions Cats, regulators and spreaders can do a much better job quicker and cheaper."

    From Jason Kuehn, ARR historian, (9/20/05): "Here is the story of Rotary #4 as I know it: Rotary #4 is a former MILW rotary plow that was based out of Tacoma and purchased by the ARR after the MILW's Pacific extension was shut down in 1980. (Somewhere in my archives I have a black and white photo of this rotary coming back into Tacoma the final spring of the Milwaukee pacific extension.) I don't know that the ARR ever actually used the rotary and it was retired probably about the time the photo of the week was taken and placed in the display at the Potter section house."

    From Don Marenzi, ARR historian, (2/7/12): "Here's my first shot at an ARR Rotary Snow Plow roster:

    1 Built as Alaska Central # 1 in 11/1905, by ALCo (Cooke works) builders # 28613. Became Alaska Northern Ry. # 1 to Alaska Engineering Commission # 1 in 1917. Became Alaska RR # 1 in 1923 described as in fair condition as of 10/1929. Scrapped in September 1946. (retired when some Caterpillar bulldozers were transferred to the ARR from the Army)

    2 Built as Colorado Midland RR # "B" in January 1900 by ALCO - Schenectady (Sold by Leslie Brothers, builders # 58.) Loaned by the C.M. to the Colorado Springs & Cripple Creek District Ry. during December 1913. To Alaska Engineering Commission # 2 in 1919. Became Alaska RR # 2 in 1923. Burned in enginehouse fire on July 18, 1926 at Curry. Rebuilt by the ARR in 1926-27. Apparently a larger diameter 'plow wheel' was used during the rebuild. Described as in good condition as of 10/1929. Retired in May 1959. Sold for scrap in 1959. Was unliked by the crews and known as "The man killer".

    3 Built as Alaska RR # 3 by ALCo-Cooke in 1930, Alco builders # 66424 (there is some evidence that this unit was originally ordered and then cancelled by the Northern Pacific RR; but no definite proof of this.) Converted to diesel power in 1967. Rebuilt in 1985 (by ARR). Retired 20xx to display in Curry 20xx

    4 Built as Chicago Milwaukee & St.Paul # 10 by ALCo (Cooke works) builders # 45425 to Chicago Milwaukee St.Paul & Pacific (Milwaukee Road) # X-900207. Converted from steam to electric power in 1958. Sold to Alaska RR # 4 in 1981. Not repainted, but
    "patch" lettered ARR 4. Received in poor mechanical condition. Not used, stored in Anchorage. Retired 1984. Donated in March 1985 to Alaska State Parks, stored in Anchorage until display site was ready. To display at Potter. 19xx.

    For the sake of completeness here are three additional rotary plows that have 'some connection' to the ARR, but were never used by the ARR:

    U.S. Army # number not known Williams Bros Machinery Co. Built in March 1954. (Bros was a name, not the word 'brothers'
    abbreviated). Plow "snow chopper/blower/rotary" this unit had a pair of six wheel trucks the U.S. Army tested it on the Great Northern. Original reason for purchase or location for the Army unknown. To Army base at Ft. Lewis, WA. The ARR inspected it at Fort Lewis in the early 1960's. The ARR didn't want it "as it had too many moving parts", so declined the offer to transfer it from the Army to the ARR. Sold to Great Northern # X-1500 in 1966. Became Burlington Northern # X-1500, then renumbered # 972556. BNSF # ? sold to Red River Valley & Western # 113 (Minnesota); in service.

    Copper River & Northwestern # X-1 built by ALCo (Cooke works) in 11/1908 builders # 43669. Left in Cordova after CR&NW abandonment. Transferred to US Army but not used by them during World War 2. After World War 2 the Army transferred ownership of it's railroad equipment at Cordova to the ARR. I've never seen any evidence that this plow was actually moved to the ARR, but they may have technically owned it. Probably scrapped in the late 1940's, possibly at Cordova.

    Santa Fe # 199398 Built by Cooke in December 1892 (Leslie Bros. builder # 44 as AT&SF # 99802. Later renumbered # 199802 in 1911 then renumbered # 199398. Reportedly the ARR inquired with the AT&SF about acquirring it in 1948. The plow had just experienced mechanical failures, and the Santa Fe decided to rebuild it instead of selling it. It was retired in 1958 and it's rotor blades, shroud and other parts were used to construct AT&SF rotary # 199361 using a former tender for the body. Now owned by BNSF: still painted as AT&SF #199361, in storage in Topeka, KS.H

    ARR Rotary History (provided by John Henderson)

  • Rotary #1: Built for the Alaska Central RR
  • Rotary #2: Ex Colorado Midland "B":  Probably little more than the blade and housing remained when it was retired and scrapped in the late fifties.  Reports from the early 1930's (I have copies with dates) indicate this rotary was involved in an accident where the frame broke and the boiler wound up on the ties.  The best guess I have is the # 2 got its steel frame and body as a "repair" after this incident.
  • Rotary #3: while it was sold new to the ARR as indicated by its builder's plate, it was almost certainly not built for the Alaska Railroad.  Checking the construction number and having had access to the correspondence files of the General Manager, I have come to the conclusion that the # 3 was built for the Northern Pacific and then canceled or refused.  A check of serial numbers will show the ARR # 3 rotary in a group of serial numbers used for NP rotaries.  A letter in the General Manager's files refers to, "the rotary plow we purchased from the Northern Pacific last year."  The date of the letter shows it can ONLY refer to the # 3.  NP historians have not been able to confirm or deny my conclusion.  Rotary # 3 was converted from seam to electric in 1967.  I photographed the rotary cab in Anchorage in September 1967 and was told it was being converted at that time.  It is still on ARR's roster.

    Recoilless Rifle
    Recoiless GunAvalanches pose a very dangerous threat to the Alaska Railroad.  Large amounts of snow can slide across the tracks, causing the rails to bend or move.  An oncoming train will hit the newly formed snow bank and a serious derailment can result.  The destruction that avalanches cause can shut operations done for hours or even days.  An avalanche on January 31, 1998 took out 200 feet of track, over turned three coal cars and closed the route for several days. To help manage the heavy snow accumulation from the hills and mountains above, the Alaska Railroad uses a 105mm recoilless rifle.  Before the snow accumulates into an unmanageable menace, workers fire a round at an overhang or drift and knock it down.

    From Frank Dewey, Alaska Railroad locomotive engineer (12/22/99): "In 1998 the (2) ARRC 106mm recoilless rifles were retired and replaced with an ex-US Army 105mm howitzer with Hy-rail gear mounted on the original gun carriage. The reason was that the "Korean War" vintage weapon had run out of ammunition. Supplied to many third world nations the 106mm stockpiles were used up by Viet Nam and numerous other wars. In 1990 the ARRC paid for the last 3000 rounds to be refurbished for avalanche control.

    "The howitzer and ammunition is kept at Tunnel Section House at MP51, between Slide Zone 49 and Slide Zone 53. It is safe there as the only way to get there is by rail or helicopter. Tests were conducted by the ARRC and the US Army/National Guard with a 105mm howitzer mounted on a 50 ft. flatcar, caboose and with a military gun crew to operate it. Now you know that there is a prototype for those HO Scale ROCO guns!

    "Originally, the gun was a home made "thing" that used either propane or acetylene gas for propellant. You might say "the mother of all potato guns" to lob an explosive package into the slide chute. Not exactly long range or accurate. It was replaced with a 75mm recoilless, but ammo stocks were already low and the more powerful 106 was soon available.

    "Sometimes the ARR will use helicopters to bomb the slide areas."


    Ballast Regulators

    Ballast RegulatorFrom Frank Dewey, Alaska Railroad locomotive engineer (12/22/99): "Originally developed to "regulate" ballast evenly over the ties before the tamper tamps it under them, the BR has become the most versatile tool in the rail inventory. If the spreader was the "Swiss Army Knife", this is the "Vege-matic". Through the years the regulator has been given plows, wings and a hydraulic broom. They have grown larger and more powerful and in Scandinavian countries are as large as a locomotive and are powered by EMD 645 engines.

    "In snow service the BR is equipped with a very large plow and much larger wings than for ballast service. They can operate with a crew of one or two people, who are not covered by the "Hours of Service Laws". Unless it is a very heavy wet snow fall the BRs can handle it with much more efficiency. At Tunnel, Divide, and Hurricane the BRs can be teamed with Cats to do a very through job of cleaning the rail.

    "The romance of rotaries and spreaders has been replaced by the newer "BR" and their operators. As an engineer, I like the work that can be done and is done by the unsung heroes the "skinners and operators"."

    Ballast regulatorBallast regulatorAdded 4/19/12: Taken in Nenana on 4-14-12 these photos by show a Ballast Regulator staged on a ready track.  This track is north of the historic depot and across the main from from the section house.  Note the extension cords running to the machine. These cords provide power to a series of heaters often refered to as a "winter package".  Engine block heater, hydraulic tank heater, oil pan heater, battery blanket, battery maintainer, etc...  Most of these installations require a minim of a dedicated 20 amp service as total draw can exceed over 5,000 watts.  This Ballast Regulator is equipped with rigid side wings used for snow removal.  They still move in and out, up and down, but are not the typical wing blades found on a regulator working ballast service.  In the dark of the winter with high daily temperatures of -20 degrees F, this little machine is responsible for clearing snow from the many crossings, switches and the guardrails of the bridge in Nenana.

    Plows
    From Frank Dewey, Alaska Railroad locomotive engineer (12/22/99): "The SD70MACs will only have "standard" EMD factory plow attached. Another snow fighting tool that the ARRC uses is the plow designed by the ARR for the GP49s and since retro-fitted to many GP40-2s. At 25 mph one of these plows can throw snow farther than the spreader. The design was so good that EMD adopted the design as a factory option. The rake of the plow is so radical that it extends back into the main frame rails, so only vertical ladder steps can be used. By FRA regulations this restricts these locomotives from being used in yard/ local switching, so they can only be attached to "Road" locomotives."

    Switches
    On November 30, 2000 the Alaska Railroad installed the first set of 80 heated, radio-controlled switching systems at Hurricane.  No longer will a member of the train crew have to get off the train, chip ice and sweep snow off the switches and manually set the switch.  The switches are activated by the engineer on board the train and will no longer be activated by hand.  These switches are kept free of snow and ice by a heater powered with a combination of wind and solar energy. All switches will be installed by 2004 for a total cost of $60 million.
