A total of 400 of these gondolas were delivered by the American Car and Foundry to the D&RGW in 1903. They were rebuilt by the D&RGW Alamosa yards in 1924 to increase capacity and to add additional strength. The kit is an exact replica of the rebuilt version and includes the classic 7' D&RGW trucks with steel wheels and Kadee® 830 couplers. In addition to mortised frame components, drill jigs are provided to speed up construction time considerably. A super-detailing kit, Product  HP-46, which includes truck brake levers and clevises, is available separately for static, display models.
