Covered Hopper, 3-Bay, ACF 4650

History: Production of the 4650-cubic foot 3-bay cars began in 1964. ACF built 2504 examples at Huntington, WV, between 1964 and 1972. The ACF 4650 c.f. 3-bay hopper was the same height and width as the 5250 c.f. 4-bay car but several feet shorter in length (and only had 3 bays!). Some railroads that were not concerned about having the larger plate C clearance 4650cf cars (which could not be used on all branchlines or at all loading facilities) opted for large fleets of 4650cf cars instead of 4600cf. UP and SP were two such railroads (all of the current UP 4600cf cars came from either MP or C&NW heritage).

Hatches: 6 30", 6 20", 3 pressed steel elongated (SP, SSW, 3 piece pressed steel continuous or 4 piece FRP continuous. Outlets: Several types of bolted or welded on outlets are used. Uses: Grain, soda ash, platic pellets. Trucks: 77 ton friction or roller bearing. 86 had 100 ton roller bearing.

Railroad/Company: ACF Industries LLC originally known as The American Car and Foundry Company and was formed in 1899.
