    OverviewTerminologyDesign and operationIn popular cultureSee alsoExternal links

    A minecart or mine cart (also known as a mine trolley or mine hutch) is a type of rolling stock found on a mine railway, used for moving ore and materials procured in the process of traditional mining. Minecarts are seldom used in modern operations, having largely been superseded in underground operations (especially coal mines) by more efficient belt conveyor systems that allow machines such as longwall shearers and continuous miners to operate at their full capacity, and above ground by large dumpers

    The tram (or dram) cars used for mine haulage are generally called tubs. The term mine car is commonly used in the United States The Romans were the first to realise the benefits of using animals in their industrial workings, using specially bred pit ponies to power supplementary work such as mine pumps. Ponies began to be used underground, often replacing child or female labour, as distances from pit head to coal face became greater. The first known recorded use in Britain was in the County Durham coalfield in 1750; in the United States, mules were the dominant source of animal power in the mine industry, with horses and ponies used to a lesser extent. At the peak in 1913, there were 70,000 ponies underground in Britain. In later years, mechanical haulage was quickly introduced on the main underground roads replacing the pony hauls and ponies tended to be confined to the shorter runs from coal face to main road (known in North East England as "putting", in the United States as "tramming" or "gathering" ) which were more difficult to mechanise. As of 1984, 55 ponies were still at use with the National Coal Board in Britain, chiefly at the modern pit in Ellington, Northumberland. Dandy wagons were often attached to trains of full drams, to contain a horse or pony. Mining and later railway engineers designed their tramways so that full (heavy) trains would use gravity down the slope, while horses would be used to pull the empty drams back to the workings. The Dandy wagon allowed for easy transportation of the required horse each time. Probably the last colliery horse to work underground in a British coal mine, Robbie, was retired from Pant y Gasseg, near Pontypool, in May 1999. In the 19th century after the mid-1840s, when the German invention of wire ropebecame available from
