HOPPER AND COVERED HOPPER CARS

Of course, one of the most specialized freight cars in use with the american railroad companies, is the hopper cars. Built to carry and to move coal, coke and anthracite throughout the history of US railroads (first coal hopper was put in service by Delaware & Hudson Railroad in 1820), this freight car was used then, for the carriage of many other materials, such as gravel, ore, sand, and in more recent times with the variant "covered" (covered hopper), also grain, cereals and other bulk products.
The open hopper car is an evolution of the gondola, a simple freight car used to transport every type of materials that they had no need protection. Their have sides of greater height and have some unloading bay on the bottom to facilitate unloading of the materials transported. Covered hoppers has the roof with loading doors to the load, with round or square shape.
The classification is varied, but generally, these types of freight cars are identified using the letter H and numbers that indicate the type of configuration. The latter, can be with two, three or four bay (the most common variants). Very few models were built with five bay, particularly in more recent times. Railroads and production companies identified always every version with the number of bay.
The Pennsylvania Railroad classified its hopper cars with the following classes:
GG, GLA (USRA two-bay hopper), GLB, GLC, GLD, GLE, GLF, GLG, GLH, GP, GQ, GV, GW, H2A, H21 (four bay hopper class built in the large number of units), H22, H24, H25, H26, H27, H30 (three-bay covered hopper with capacity of 70ton), H31, H32, H33, H34, H35, H36, H37, H39, H40, H41, H42, H43, H44, H45, H46, H47, H48, H49, H50.
For PRR, the variants H21d was the first type of covered hopper produced for cement transport. In 1957, PRR had in service several thousands of hopper car.
