The YG class of Indian Railways were 2-8-2 tender locomotives built for metre-gauge. It is one of the standard designs developed as the evolvement from the Indian Railway Standard locomotives .

History

[edit]

The YG class was the most mass-produced metre-gauge freight locomotive in India after the partition. Between 1949 and 1972, a total of 1,074 locomotives were built by nine different manufacturers.[3]

Although designed as goods engines, the YG was often used on passenger trains. It replaced the 1927-built class YD.

YG 3573, completed on 5 February 1972 by Chittaranjan Locomotive Works, was the last steam locomotive built in India.[4]

Many of the locomotives were in use until the end of the 1990s. The last three examples, 3318, 3334 and 3360 were in regular service with Western Railways in 1999, being used on freight and passenger trains from Wankaner to Navlakhi via Morbi on the Gulf of Kutch.[5]

Design

[edit]

The YG class was designed as a metre-gauge variant of the broad-gauge class WG, but externally, they were broadly similar to the class YP passenger locomotives. The biggest difference between YG class and the preceding YD class was the use of bar frames, which were lighter and easier to manufacture than the plate frames.[3]

In addition, the YGs had the latest technical features in a steam locomotive of its era, such as steel fire grates, rapidly heating boiler tubes, combustion chambers and large-area superheaters. Improved boiler conditions allowed the combustion of low-grade Indian coal with high ash content.[7]

Allocation

[edit]

The YG class was widely used throughout India. By 1976, 1,059 locomotives were still rostered on the following regions of Indian Railways:[8]

Region Number
Central Railway 24
Northern Railway 165
North Eastern Railway 293
Northern Frontier Railway 106
Southern Railway 159
South Central Railway 151
Western Railway 161

East African exports

[edit]

In 1976, five locomotives, numbers 3563, 3564, 3551, 3550, and 3549, were sold to East African Railways. These were manufactured in 1971 and 1972, and were overhauled in India beforehand. Differences include the absence of smoke deflectors and some other minor adjustments. The five locomotives were placed in the 2701-2705 numbering sequence, being designated as Class 27II, and were passed on to Tanzania Railways after the breakup of the EAR, before being withdrawn and scrapped in 1993.[9][2]

Preservation

[edit]

At least 50 locomotives have been preserved.[10] In 2000, two more examples were sold to private individuals in the United States, although their subsequent fate is unknown.[5]
