Cart from 16th century, found in Transylvania A dumper minecart used in the Basque Country, currently at the Minery Museum.. A minecart, mine cart, or mine car (or more rarely mine trolley or mine hutch) is a type of rolling stock found on a mine railway, used for transporting ore and materials procured in the process of traditional mining.
Wheels coupled to the main/side rods, through which the power developed in the cylinders (24) is transformed into tractive power at the rails. [1] [2] [5] [3]: 28 The weight of bearings and coupling rods on the driving wheels is counterbalanced with cast-in weights to reduce "hammering" on the track when the locomotive is under way. [3]: 21

This limited some early research railguns to one shot per service interval. The inductance and resistance of the rails and power supply limit the efficiency of a railgun design.
