Over half of all new autos make their first long trip by train, riding in enclosed tri-level auto rack cars. Since autos are smaller and shorter than trucks or vans, the third deck increases carrying capacity; usually 15 mid-size or 18 compact cars make up a full load. As some of the longest and tallest equipment in operation, tunnels, bridges or other obstructions can present routing problems that require detours. To avoid this, a modified tri-level design was introduced in the mid 1970s. The 89' flat car that carries the rack is a special low-level car, easily identified by the side-sill cut outs that provide left and right side clearance for the trucks. In place of the usual 33" wheels, these cars ride on smaller 28" wheels to further reduce overall height. In service with most major roads, they can be found in the staging areas of every auto assembly plant, as well as reloading with import cars for their return trip. Fully assembled and ready for service, these HO Scale models come in a variety of colorful, modern schemes and are complete with working knuckle couplers. they're perfect for use with the Distribution Facility (933-3076) or to model bridge traffic moving across your layout. For a larger fleet, 2-Packs in matching roadnames, but with different car numbers (932-24851 series) are offered separately.
