Talk:Hopper car

message: Does "Hopper car" refer to all Hopper cars, both covered and uncovered, or only to uncovered ones? In other words, are covered Hoppers a subset of Hoppers, or an entirely different type? Propaniac (talk) 15:45, 14 January 2008 (UTC)
replies: text: Covered hoppers could be considered a subtype of hoppers in general since covered hoppers are in their most basic form open hoppers with covers and sometimes additional unloading equipment (i.e. airslide hoppers), but they are treated as different types of cars in railway operations.  Open-top hoppers (at least in North American practice) are more often used in unit train service, while covered hoppers frequently appear in mixed manifest freight trains.  Since they are used differently, its logical to examine them as separate classes of equipment despite the similarities. Slambo (Speak) 18:36, 14 January 2008 (UTC)

text: "Hopper car" does refer to all such cars.  Slambo, above, does explain that the differences have to be considered in the article although the basic structure is the same.  The cover is a not insignificant detail for those using the car, whether wanting the contents to not blow away or wanting to drop coal from an overhead conveyor into the car.  -- SEWilco (talk) 18:45, 14 January 2008 (UTC)
thread_title: Open vs. covered

message: I would think an encyclopedia would have typical values for the capacity of train cars, including hopper cars.  How many tons of coal does one hopper car typically carry, how many gallons does a typical tank car carry, how many cubic yards fills a typical gondola, etc.?  I realize there are ranges and not exact values, but for the sake of discussion, what might be a round number?  Thanks.  192.31.106.34 (talk) 19:50, 1 July 2009 (UTC)
replies: text: Due to the wide variety, a compete list of all capacities would be rather long. Suffice it to say (until someone can start such a list) that modern US railroad hopper cars range from under 2000 Cubic Feet capacity up to about 4800 CF. Capacity is limited by weight with most modern railcars limited to 100-110 US Tons overall weight. Shorter cars are used where the product is dense, larger cars are for less-dense product.
