Eventually, the car was heightened, and lengthened for ever-larger loads. As Mike Schafer notes in his book, "Freight Train Cars," this development proved a major deviation from English design and was one in a series of differences that made American railroading unique.

DESIGN OPTIMIZATION OF A CAR -TRUCK STAND Abstract Car -truck stands are used during maintenance operations to support one end of a freight car or a commuter car used in railway industry. Usually, the y consists of several pieces of steel tubes and other st eel members welded together to form a rigid frame structure.

Initially cars were roughly square, with four fixed wheels Increased capacity => increased length => longer wheelbase excessive wear on wheels and track more derailments 8-wheel car with swivelling trucks/bogies introduced in 4-wheel Freight Car 4-wheel (short) freight cars continued to be used for higher density loads – e.g.

coal, ore until late 19th century. Eventually trucks with cast-in journals won out, although freight cars with Andrews and Vulcan trucks could still be seen in revenue service through the end of the steam-era.

The continued development of cast truck design was dependent on the ability to test the various designs.

For complex routing puzzles, as with bulk materials and liquids (dealing with compartments), over 5% savings are obtained, even when using only 15 or 20 trucks.
