Fireless locomotive

Preserved Porter Locomotive Company No. 3290 of 1923 powered by compressed air

A fireless locomotive is a type of locomotive which uses reciprocating engines powered from a reservoir of compressed air or steam, which is filled at intervals from an external source. They offer advantages over conventional steam locomotives of lower cost per unit, cleanliness, and decreased risk from fire or boiler explosion; these are counterbalanced by the need for a source to refill the locomotive, and by the limited range afforded by the reservoir.

Typical usage was in industrial switching where a conventional locomotive was too noxious or risky, such as in a mine or a food or chemical factory; they also saw use where the source of air or steam was readily available.

They were eventually displaced by Diesel and battery electric locomotives fitted with protective appliances; these are described as Flame-proof locomotives.[1]

Lamm & Francq fireless tram engine, 1888

An early application of the fireless locomotive was to street tramways in the USA. Emile Lamm developed two types of fireless locomotive, one using ammonia and the other using stored steam. Lamm founded two companies, Ammonia & Thermo-Specific Propelling Company of America in 1872 and (with Sylvester L. Langdon) Lamm Fireless Engine Company in 1874.[2] Lamm's fireless engines were briefly popular, both in the USA and in France, but were soon displaced by electric trams. The French locomotives were built in association with Leon Francq, under the name Lamm & Francq.

The fireless system then gained a new lease of life for industrial shunting locomotives. Any factory which possessed a stationary boiler could use it to charge a fireless steam locomotive for internal shunting operations. Fireless shunting locomotives became especially popular in Germany and some remained in service into the 1960s. Fireless industrial shunters were usually of the 0-4-0 or 0-6-0 wheel arrangement but some 0-8-0s were built, such as this example by La Meuse of Belgium.[3]

The Swiss company, DLM, was recently (2012) trying to promote the fireless steam locomotive as an environmentally-friendly alternative to the diesel locomotive for shunting. DLM claims that diesel shunters typically spend 75% of their working time with the engine idling.[4]

Motive power types


A fireless steam locomotive is similar to a conventional steam locomotive, but has a reservoir, known as a steam accumulator, instead of a boiler. This reservoir is charged with superheated water under pressure from a stationary boiler. The engine works like a conventional steam engine using the high pressure steam above the water in the accumulator. As the steam is used and pressure drops, the superheated water boils, replacing the used steam. The locomotive can work like this until the pressure has dropped to a minimum useful level or the water runs out, after which it must be recharged.

European fireless steam locomotives usually have the cylinders at the back, while American ones often have the cylinders at the front, as in a conventional locomotive. Major builders of fireless steam locomotives in the UK included Andrew Barclay and W.G. Bagnall.

Compressed air

Compressed air locomotives are used mainly in mines, but have also been used on tramways. (See Mekarski system)


Several hybrid locomotives have been built that have either used a fire for part of the time, e.g., Fowler's Ghost of London's Metropolitan in 1861, or have used a fire to superheat stored steam, such as the Receiver Locomotives built by Sentinel Waggon Works. None has been a success.

Wheel arrangements

Most fireless locomotives have been of 0-4-0 or 0-6-0 wheel arrangement but there have been some 0-8-0 and even a few 0-10-0. Some 600 mm (1 ft 11 58 in) gauge 0-10-0 fireless locomotives from the German company Henschel were used in the construction of the Baghdad Railway, probably to avoid the risk of carbon monoxide poisoning during the boring of tunnels.[5]

Another German company, Hohenzollern, built some articulated fireless steam locomotives with a cab at each end. Only one of the bogies was powered, making the wheel arrangement B-2.

Current use

Steam traction became unfashionable in the 1940s and was largely replaced by diesel or electric traction. However, fireless steam has its merits, especially where there is an abundant cheap source of steam, such as in industrial sites, at thermal power stations or refuse incineration plants, where fireless steam locomotives are used for shunting at very low cost.

As they do not emit any exhaust except steam, they can shunt into buildings without endangering the workforce with noxious fumes.

Considering that shunting locomotives are typically working for only about 10% of the time, 90% waiting for work; a diesel locomotive, idling most of the time, burns too much fuel producing nothing.[6] A well insulated modern steam accumulator can preserve pressure over many hours. Thus the operating cost of a fireless steam shunter can be far less than that of a comparable diesel.

Fireless locomotives are also safer to operate than conventional steam locomotives, aside from the elimination of ignition hazards. The primary cause of a locomotive boiler explosion is the depletion of boiler water, through inattention or excessive use, exposing the crown sheet directly to the flames of the firebox, weakening it to the point of failure. A fireless locomotive eliminates this danger—if it runs out of sufficient water, it simply ceases to move—although precautions must be taken as with any other pressure vessel. Furthermore, they did not require careful monitoring of water levels and boiler pressure, nor careful distribution of coal in the firebox for efficient combustion, and thus could be operated by less-skilled staff, not requiring a fully qualified locomotive engineer and fireman.


Several locomotive builders produced fireless engines throughout the 20th century. Meiningen Steam Locomotive Works was still building them in the 1980s. Some fireless locomotives are in daily use even in 2013. One example is the large coal-fired power station in Mannheim where coal is delivered by rail in long trains of self-discharging hopper wagons. Three fireless engines are used to shunt the hoppers on the premises of the power station.

East Germany, preferring to use its abundant supply of lignite to imported fuel, used fireless engines extensively. A series of 200 fireless locomotives was built at Raw Meiningen as late as the 1980s.


Switzerland had used older fireless engines in industry, such a breweries. In 2010, the steam company Dampflokomotiv- und Maschinenfabrik DLM refurbished two locomotives of the German Meiningen type and modernised them for use on sidings. [7]


Numerous examples have been preserved across the world.


The German WorldHeritage has a list of steam accumulator locomotives preserved in that country. It entails over 100 preserved fireless engines, 8 of them operational.[8]

South Africa

The Electricity Supply Commission of South Africa (ESKOM) has preserved two fireless steam locomotives. They are Bagnall 0-6-0F no. 2571 of 1937 and Hawthorne Leslie 0-4-0F no. 3858 of 1935.[9]

United Kingdom

One notable example is "Lord Ashfield" (Andrew Barclay works no. 1989 of 1930) at the Museum of Science and Industry in Manchester. It ran in limited service in the 1990s sharing a steam supply with the stationary exhibits.[10]

The Ayrshire Railway Preservation Group has rebuilt its Andrew Barclay 0-4-0 fireless locomotive (Works Number 1952 of 1928) and intends to operate it as part of a demonstration freight train. The engine is due to start running on Sunday, 5 July 2015.[11]

United States

The North Carolina Transportation Museum in Spencer has a fireless steam locomotive, the North Carolina Power and Light #3 0-4-0.
