Accurail HO scale PS-2 4750 covered hopper kit

Read this review from Model Railroader magazine
Accurail HO scale PS-2 4750 covered hopper kit
An injection-molded plastic kit of Pullman-Standard’s best-selling PS-2 of all time is now available from Accurail. The HO scale 4,750-cubic-foot-capacity covered hopper features a one-piece body; separate underframe, slope sheets, and end frames; and plastic wheelsets.

Pullman-Standard produced the 4750 covered hopper from 1972 to 1981. More than 56,000 cars were built over the course of the production run. In addition, Evans Products and North American Car Co. produced “clone” cars from PS-supplied kits.
The Accurail kit is an easy evening project.
The contents of the Accurail kit, except for the steel weight, are shown below. All of the parts have crisp detail and are free of flash (excess plastic that oozes out of the mold). A bit of cosmetic filing is required to clean up the edges attached to the sprues.

Well-written and illustrated instructions take you through the 16 steps needed to complete the kit. I worked on the car in short bursts over three days, but the model could easily be finished in an evening.

Our sample is decorated as Atchison, Topeka & Santa Fe no. 312856. The full-size car was part of a 1,000-car order (nos. 312800 through 313799) built by PS between December 1972 and February 1973. The covered hoppers were part of the railroad’s GA-180 class.

The lettering placement matches prototype photos in print and online. All of the lettering is crisp and legible under magnification. However, the lot number is wrong. This batch of Santa Fe cars was built under lot 9617, not 3032 as printed on the model.

There were some Santa Fe-specific detail errors. The triple valve and air reservoir are misplaced, the angled stiffener over the middle eight exterior posts was omitted, the Morton (round holes) running boards are incorrect for GA-180 class cars, and the B-end crossover platform shouldn’t be notched (the brake chain went behind it, not through it).

Based on the combination of details, the model more closely follows the design of a circa 1978 PS 4750. The model’s dimensions follow prototype drawings in the 1980 Car and Locomotive Cyclopedia (Simmons-Boardman).

The kit includes Accumate couplers, which are mounted at the correct height. At 4.3 ounces, the covered hopper is .5 ounce too light based on National Model Railroad Association recommended practice 20.1. Adair Shops ( offers regular
and heavy weight kits for this car. The injection-molded plastic 33" wheelsets are correctly gauged. However, the car should have 36" wheelsets.

In an era of ready-to-run models, its refreshing to see a new, well-though-out kit on the market. Though the model isn’t an exact match for Santa Fe’s GA-180 class, it is correct for cars owned by many other railroads.
