[[File:Indian_Railways_Class_YC.jpg|thumb|Vulcan Foundry brochure of the YC class]]<br />
The '''YC class''' was a class of [[4-6-2]] tender locomotives introduced from 1928 for the predecessor [[Metre-gauge railway|metre-gauge]] railway companies of the [[Indian Railways]] (IR) and the [[Rail transport in Myanmar|Burma Railways]] (BR),{{efn|name=burma|Later separate from British India.}} as part of the metre-gauge Indian Railway Standard (IRS) series of locomotive designs.<br />
<br />
== History ==<br />
The YC class was the larger and heavier version of the [[Indian locomotive class YB|YB class]], fitted with a larger boiler and cylinders, thus increasing the weight by six tons. The [[Axle load|axle loading]] was also increased by two tons, compared to the YB's 10-ton axle load, as a result of the fitting of larger components. Both the YBs and YCs were designed to haul passenger trains.{{sfn|Hughes|Jux|1977|p=34}}<br />
<br />
Between 1928 and 1932, a total of 28 locomotives were built. Only the [[Bombay, Baroda and Central India Railway]],{{efn|name=exBBCIR}} the [[Madras and Southern Mahratta Railway]] and [[Myanma Railways|Burma Railways]] rostered both the YCs and YBs in their fleets. The other Indian railway companies preferred to use the lighter YB class design, which had well over 200 examples built.{{sfn|Hughes|Jux|1977|p=30}}<br />
<br />
=== Burma ===<br />
After Burma Railways came under control of the government of [[British rule in Burma|British Burma]] recently separated from the British Raj in 1937, its stock including the YC class were taken over. During the [[Burma campaign]] and the [[Japanese occupation of Burma|Japanese occupation]], most of the YC class locomotives were destroyed. After the war, Burma Railways acquired 10 more locomotives, of which two are now preserved.<ref name="fernexpress">{{Cite book |title=Burma Railways, Dampflokomotiven 1. und 2.

<br />
=== India ===<br />
After the [[partition of India]] and the amalgamation of private railway companies to form Indian Railways, all 15 locomotives built for the Indian proper were transferred to the [[Southern Railway zone]] that was established in 1951. Initially given the numbers 550 to 564, as part of the introduction of a new numbering scheme in March 1957, the YCs were renumbered 30139–30153.{{sfn|Hughes|Jux|1977|p=30}}<br />
<br />
By 1975, none of the YC class were listed on any Indian Railways roster.{{sfn|Hughes|Jux|1977|p=96}}<br />
