Boxcar

The D&RG Class 5 Boxcar is a freight car used to transport tools, seed pallets, and even grain, the latter generating grain doors upon loading. It was part of the original roster of rolling stock. 
Between 1878 and 1883, the Rio Grande shops built the railroad's largest class of boxcars: over 2500 cars with a capacity of 10 tons and a length of 24ft. In 1903, some of these cars (those being in the best shape) were rebuilt with new trucks increasing their capacity to 20 tons, and with automatic couplers and air brakes to comply with the new Interstate Commerce Commission regulations. Another hundred boxcars from the same class have been more heavily modified between 1884 and 1895 with new 20-ton trucks and a length increased to 27ft. 
The car series was numbered 4000 - 4099 (as of 1902) http://drgw.free.fr/DRGW/Freight/Boxcar/Couvert_en.htm
