Steam locomotives of India

The X class is a metre gauge rack and pinion compound locomotive used by the Nilgiri Mountain Railway in the Nilgiri Hills of southern India. They are used on the 28-kilometre-long (17 mi) section between Coonoor and Mettupalayam, where the line reaches a gradient of 8%. The railway uses the Abt system on these steep sections. The locomotives have two high-pressure and two low-pressure cylinders, located outside of their frames. The low-pressure cylinders drive the rack gears, and are positioned above the two main high-pressure cylinders, which drive the main wheels.

The United States Army Transportation Corps S160 Class is a class of 2-8-0 Consolidation steam locomotive, designed for heavy freight work in Europe during World War II. A total of 2,120 were built and they worked on railroads across much of the world, including Africa, Asia, all of Europe and South America.

The Indian locomotive class SP (Standard Passenger) were a class of passenger broad-gauge locomotives introduced around 1905 that were one of seven standard locomotive designs developed by the Engineering Standards Committee (later the British Engineering Standards Association (BESA)) for the broad-gauge railways of British India.

The Indian locomotive class SG is a class of Indian steam locomotives used for goods trains. Its class designation, SG, stands for Standard Goods. It was, by number of locomotives built, one of the largest steam locomotive classes built in the United Kingdom. It was one of the BESA locomotives developed by the British Engineering Standards Committee, later called the British Engineering Standards Association (BESA).

The DHR D Class was a 2 ft (610 mm) gauge Garratt-type articulated steam locomotive used on the Darjeeling Himalayan Railway (DHR) in West Bengal, India.

The DHR B Class is a class of 2 ft (610 mm) gauge saddle tank steam locomotives used on the Darjeeling Himalayan Railway (DHR) in West Bengal, India.

The Bengal Nagpur Railway class NM was a class of ten 4-8-0+0-8-4 Garratt locomotives manufactured by Beyer, Peacock & Company in England. This was modified N class Garratt. It had Thermic siphon and arch tubes for better performance. It worked on the Bilaspur-Katni line and Anuppur-Chirmiri branch line for hauling coal. Probably because of Poppet valves, they retired early.

The Bengal Nagpur Railway class N was a class of 4-8-0+0-8-4 Garratt steam locomotives built by Beyer, Peacock & Company in England in 1929. At the time of their construction, they had the largest water capacity of any Garratt, in addition to being the largest locomotives in India. The class N Garratts were introduced following successful performance results from the earlier HSG Garratts. Due to their heavy weight, they were restricted to 90 lb/yard rails. They had straight-ported cylinders; it is not known if this suited them for hauling slow, heavy coal traffic. Like the earlier HSG Garratts, they worked on the Chakradharpur-Jharsuguda and the Anara-Tatanagar sections. After electrification, they were used at Rourkela. They could haul 2400 tonnes on a 1 in 100 gradient.

The Indian locomotive class WT was a class of heavy tank locomotives used on 5 ft 6 in (1,676 mm) broad gauge lines in India from 1960. These locomotives were built to operate local trains in Eastern Railways zone on Howrah to Burdwan main line.

The Indian locomotive class WU was a class of steam locomotives used on 5 ft 6 in (1,676 mm) broad gauge lines in India.
