A fireless locomotive is a special design of steam locomotive that receives its steam from an external pressure vessel. It can be used in potentially explosive environments, such as in the chemical industry, as it does not have any combustion.
The steam accumulator is a simple pressure vessel. It is filled with steam and water before starting operation. If steam is withdrawn from the pressure vessel, the existing hot water supplies new steam. This principle allows these locomotives to operate for several hours without refilling, depending on the load.

Our locomotive No. 13 was put into service in 1911 at BASF, Ludwigshafen with the nickname “Olga”. In 1932 the locomotive was sold to Raschig GmbH, Ludwigshafen and was in service there until 1975. Until 1977 it was stored there as a reserve and was then donated to the railway museum. It has been part of our exhibits since 1978.
