This is the HO Scale Diesel Fueling Facility Kit from Walthers.
If Your HO Railroad Runs Diesels, You Need This Kit!
Based on prototypes introduced in the 1940s when railroads began the shift from steam to diesel power, diesel fueling facilities were originally placed on the servicing leads near roundhouses. Today, you'll still find them at terminals where locos are serviced between runs and out on the road at crew change and train inspection points.
The new Diesel Fueling Facility is an authentic addition to any scene and includes everything to complete a two-track fueling facility; storage tank, fuel crane, water crane, pump house and top unloading rack (for unloading diesel fuel from tank cars). For modern era modelers, environmental track "pans" to catch fuel and oil spills are also included.
Storage Tank: 5 x 2-3/4" 12.5 x 6.8cm
Platform: 11 x 7" 27.5 x 17.5cm
Unloading Rack: 1/2 x 3/4 x 2-7/8" 1.2 x 1.8 x 7.1cm
