The Begal Nagpur Railway class HSG was a class of two 2-8-0+0-8-2 Garratt locomotives.
After NWR's GAS class, BNR conducted similar experiments for pulling heavier trains up the ghats with successful results. Its parts were similar to BESA heavy goods 2-8-0s. They worked on the Chakradharpur-Jharsuguda section coupled to each other. After electrification they became obsolete. In the end, they were stationed at Kharagpur workshops. They were the first successful class of Garratts.[1]
