These distinctive cars are the railroad equivalent of a dump truck. Designed to carry up to 100 tons, the prototypes are fitted with large pneumatic cylinders and side doors, and can dump to the left or right of the tracks. While used primarily in work train service for dumping ballast, fill and rip rap, they can also be used in revenue service to carry sand, gravel, cinders, coal, limestone and other loose bulk materials used in industry.
 
These HO Scale models come fully assembled with all grab irons installed, Proto MAX(TM) all-metal knuckle couplers and free-rolling trucks with RP-25 metal wheelsets.
