21C18 British India Line is a preserved SR Merchant Navy class steam locomotive built by the Southern Railway in 1945.

21C18 was withdrawn from service in August 1964 and sold on to Woodham Brothers scrapyard in Barry, South Wales where it arrived in December of the same year.

Because of mechanical issues with the class, including an accident at Crewkerne in 1953 which involved 21C20 Bibby Line,[1] it was decided to rebuild all 30 locomotives to a more conventional design.

In November 1979 British India Line was purchased for preservation by Richard Heather and John Bunch, and in March 1980 the engine was moved to the Mid Hants Railway (MHR) where restoration to full running order was to take place.

[3] After light and loaded test runs earlier in the year, it was repainted from its unlined black livery into BR Brunswick Green with the late crest on its tender.

[citation needed] Since returning to service the engine has made main line trips and operated on the Wensleydale heritage railway.
