Per the Official Railway Equipment Register of October 1974: ARR 8018 is a 54' boxcar. It has a door opening that is 6'10" wide by 11' 10" high. It has a capacity of 110,000 lbs. and is restricted to "Low Density Products Only". In October of 1974 it was a member of the 26 car class numbered from 8000-8025. It has an American Association of Railroads (AAR) Mechanical Designation of XM. An XM boxcar is a general service boxcar equipped with side or side and end doors.

Observations about this car: This car has the XM symbol painted between the vertical rails of the short ladder on the right side
of the car. Although the car is retired it looks like there is still a seal or tag on the on boxcar door. It also has an ACI (Automatic Car Identification) label applied slightly to the left of the logo on the right hand side of the car. ACI labels were required on all freight cars from 1967 to 1978 and may still occasionally be seen on freight cars today.

Comments about the photo: The rusty wheels on this car suggest that it had been sitting at this location for quite a long time before this picture was taken. This picture was taken at the small BN (NP) yard just north of S. Horton St. - Seattle, Wa. The only additional spray paint on the car indicates that this car has been retired. There is something wonderfully pristine about a freight car with no graffiti.
