The YG Class 2-8-2 was the most common meter-gauge goods locomotive in post-independence India. Chittaranjan and TELCO in India and several foreign manufacturers built many of them. Indian Railways built its last steam locomotive in 1972; it was a YG.

TECHNICAL NOTES
YGs had American-style bar frames supporting the boiler. Pound for pound, bar frames were lighter than the plate frames and were easier to manufacture.
The YG was essentially a scaled-down version of the broad gauge WG. It had a lot of parts in common with the YP 4-6-2. Not surprisingly, it resembled a YP in appearance. Though designed as a goods locomotive, the YG also hauled passenger trains since its maximum permitted speed was only 5 mph less than that of the YP.
Other technical features of the YG include: Spring-loaded inter-drawgear; spring controlled engine leading and trailing bogies; high centre of gravity to ensure better riding qualities; Timken roller bearings on all bogies, trucks and eccentric cranks; improved boiler proportions for burning low grade, high ash Indian coal.
