The Bengal Nagpur Railway class N Garratt was a class of steam locomotives built by Beyer, Peacock & Co. 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. Due to their heavy weight, they were restricted to 90 lb/yard rails. In 2006 Locomotive #811 at Kharagpur workshop was reactivated and used on a few runs before being stored again. In order to activate the locomotive, many parts were borrowed from locomotive #815 at the Delhi Railway Museum. The parts were later returned and refitted to #815 which itself was given a cosmetic overhaul. In 2018 a second attempt to activate #811 was made. This time all missing parts were fabricated in a US$400,000 refurbishment that was put out to public tender. The locomotive has made just one trial trip up to the end of 2019. Wikipedia.
