The railroad boxcar is an amazing thing. It is actually an
enclosed, water resistant box on wheels. Access is gained through
sliding doors (single or double) on either side and the floor is strong
enough to support the weight of a loaded forklift. They can be from
40 to 90 feet in length and carry 70 to 100 tons. Boxcars carry auto
parts, appliances, food goods, consumer products, pulp, paper board, scrap
paper, newsprint and lumber. Boxcar usage has dropped significantly
since the 1980s due to the increased usage of covered hoppers and intermodal
trailers/containers. Currently, boxcars make up approximately 16%
of a typical consist. The history, maintenance and capacity information
for a boxcar is displayed on its side.
Boxcars are defined by their capacity and dimensions. A boxcar's cubic capacity is obtained by multiplying the inside dimensions - length, width and height (of the side wall). The boxcar's trucks also determines the weight it can handle. Trucks are rated for 70 ton (33" diameter wheels/220,000 lbs.) and 100 ton (36" diameter wheels/263,000 lbs.). As of 1/1/95 the AAR allowed freight cars with 100 ton trucks to be rated at 286,000 lbs provided the car could structurally support the load. The load capacity of the car is the difference between the Gross Rail Load (GRL) rating and the empty weight of the car. Finally, boxcars are defined by their overall length and height. Length is used to determine maximum number of cars that can be put into a siding or staging yard. Height is used to ensure proper clearance through tunnels and various overhead apparatus. The maximum height of a boxcar is 17 feet.
Boxcars come in two door types, the plug door and the sliding (corrugated) door. They can have one or two doors per side. Door widths are 10' or 12' for singles and 16' for doubles. The sliding door system keeps both the weather and direct sunlight out. It slides using two rollers in a door track and can be opened or closed by pulling on the door handles. The plug door system closes with a final inward movement (similar to most van sliding doors) that seals the door flush with the interior of the boxcar. This provides a much better seal than the sliding door boxcar. A rotating lever on the door activates a gear system to "plug" and "unplug" the door.
Current boxcar technology includes movable bulkheads, end cushioning and air bags to improve efficiency and prevent damage. Insulated cars can carry perishables which do not require mechanical refrigeration cars. Refrigerated boxcars now use carbon dioxide "snow" to maintain a cold temperature for shipping meats, juice and other frozen products.
Boxcars can also be used for storage and maintnenace of way. Numbers
95101, 95102 and 10811 are used by ARR Supply between anchorage and Fairbanks
to load company materials.

| Boxcar number 10366 in Healy, AK (7/4/98). These were built by Pullman Co. or A.C.&F. in 1943. These ex-Troop sleeper/kitchen cars were rebuilt by C.F.C&P. in 1948 & put into service. Only a handful of these are still in MOW use with the rest turned over for scrapping. | Sixty-foot insulated boxcar #10803 at Anchorage (10/8/98). This car was made by P.C. & F. and the ARR purchased 35 of them (nos. 10800-10834) in 1965. More | Disaster strikes! The person who passed this photo on to me did not know the cause of the fire or the contents of the boxcar. Please send me an email message if you have any information. Did anyone bring marshmellows? | The ARR used several boxcars as billboards. They were placed by the Anchorage depot in early 1981 and were pulled out sometime between 1986 and 1991. One of these cars now sits behind the ML&P yard on First Avenue in Anchorage. |

| This is the old style ARR boxcar. Sometimes a box car is converted to an ice reefer like this one. | Old boxcars never die they just change their owners. These boxcars had their trucks removed and are now used as commercial storage units. I remember traveling out west and seeing home owners use them as storage barns. | Still in use as of September 2006! | HiCube boxcars (8000 series) |
