Offering for sale a brand new and boxed example of a Bachmann Branchline Model Railways GLW HTA THRALL BULK “EWS” Coal Hopper Wagon model reference number 37-853.
A hopper car is a type of railroad freight car used to transport loose bulk commodities such as coal, ore, grain, and track ballast. Two main types of hopper car exist: covered hopper cars, which are equipped with a roof. The other an open hopper car, which as the name would suggest does not have a roof. This type of car is distinguished from a gondola car in that it has opening doors on the underside or on the sides to discharge its cargo.
Later examples have also been equipped with an end sliding door. The development of the hopper car went along with the development of automated handling of such commodities, with automated loading and unloading facilities. Hopper cars have been used by railways worldwide whenever automated cargo handling has been desired.
