Minecarts range in size and usage, and are usually made of steel for hauling ore. Shaped like large, rectangular buckets, minecarts ride on metal tracks and were originally pushed or pulled by men and animals (supplemented later by rope-haulage systems). They were generally introduced in early modern time, replacing containers carried by men. Originally, they didn't run on a real "rail", where the wheels would have a rim to fit into the tracks, but with plain wheels on a wooden plank way, hold in track by a pin fitting into a guide groove, or by the underside of the cart itself which was lower than the wheels and fitted between the planks ("Hungarian system"). As mines increased in size and output, the aforementioned methods became impractical because of the distances and quantities of material involved, so larger carts would be used, hauled by
narrow gauge diesel and
electric locomotives (in coal mining operations, where gas that is flammable would present a problem, the locomotives would be
flameproof or
battery powered). These were also used to pull trains transporting miners to the workfaces. Minecarts were very important in the history of technology because they evolved into
railroad cars.

Lorry or mine car An open railroad car (gondola) with a tipping trough, often found in
mines. Known in the UK as a tippler or
chaldron wagon and in the US as a
mine car. File:Mining_cart.jpg|Mining cart shown in
