This Steam Fire Pump was built by Merry Weather Co., London, England in the year 1934. Merryweather & Sons were makers of Steam Fire & Tram engines. Founded in 1791 in Great Britain, they made some of the finest steam boiler engines for Railways around the world.

This system used to have a vertical boiler on a horse-driven carriage. The pump having a copper boiler was operated by steam and was successfully used as a mobile fire extinguisher during the bygone steam era in the meter-gauge sections of Mysore State Railway. It was applied to improve the water pressure once it was steamed up. It was reckoned that an engine could get enough pressure within 10 mins of a call out; steaming up could be started before leaving the fire station so there could be enough pressure by the time they arrived at the scene of fire.
