A hospital train is a railway train with carriages equipped for the provision of healthcare. Historically this has ranged from trains equipped to transport wounded soldiers, with basic nursing and first aid facilities on board, to fully equipped mobile medical centres, sometimes including operating theatres and nursing wards.
The first hospital train was built during the Crimean War in the 1850s. Poorly operated logistical supply networks and inadequate health provisions for the British army encamped around the Russian port of Sevastopol caused a public outcry in England. To alleviate these problems, the Grand Crimean Central Railway was initially built by a partnership of English railway contractors led by Samuel Morton Petoin 1855, to supply ammunition and provisions to Allied soldiers. Within three weeks of the arrival of the fleet carrying materials and men the railway had started to run and in seven weeks 7 miles (11 km) of track had been completed. The railway was a major factor leading to the success of the siege. The line was surveyed by Donald Campbell.
Although the railway's primary function was the supply of armaments and equipment, the train was also used for the transport of the wounded. The first such instance of this occurred on April 2, 1855, when the train was used to carry the sick and injured from the plateau down to the dock at Balaclava. Towards and during the second winter, the supplies carried by the railway were different. The siege had ended, carriage of ammunition was less important, and the supplies related more to the accommodation and comfort of the troops. These included huts to replace tents, clothing, food, books and medical supplies. Following the completion of the Sardinian branch, the railway had reached its limit. In all, it measured about 14 miles (23 km) plus a few miles of sidings and loops.
Hospital trains were subsequently used during the Franco-Austrian War, the American Civil War and the Franco-Prussian War. They were also used extensively during colonial campaigns, notably in the Anglo-Zulu War. However, these hospital trains remained primarily as troop trains, with the passengers restricted to the wounded and dying. They had little or nothing in terms of onboard medical facilities, although nurses traveled with the wounded and the carriages of the trains were painted with red crosses to indicate their humanitarian role and to prevent enemy attack.
