There are a total of eight diesel locomotives in operating condition at the Jokioinen Museum Railway. Almost all work trains are operated with these diesel locomotives. They are used in track maintenance trains and for switching railway cars and steam locomotives on railway yards.


Museum railway's newest and most powerful locomotive is TU4-type diesel locomotive number 2091. This locomotive is made in the Kambarsk locomotive factory in 1970. The factory is located in Udmurt Republic of former Soviet Union. TU4-type (Russian entry ТУ4) narrow-gauge locomotives were produced several hundred units between years 1962-1974. Number 2091 has been used, inter alia, in Lithuania. Last it was used in Tituvenai turf track in Middle-Lithuania. Locomotive was withdrawn from service in 2000, and stood after it several years outdoors.

Museum Railway Association purchased the locomotive in the summer of 2009. The locomotive had reached rather poor condition caused heavy use and storage outdoors. TU4 was transported to Estonia in June by truck roller. Extensive repairs were made in the Baltic Marine Group AS workshop in Türi. Former Soviet military tank engine was replaced by a new engine manufactured by Scania. The new one was a Swedish bus engine built in 1990.

For locomotive had to also do a lot of different metal and electrical work and other repairs. Finally, the locomotive was painted in appropriate colors.

The repair work was partially financed by Finnish Ministry of Transport and Communications.

TU4 arrived in Jokioinen Museum Railway in Friday 30 October 2009. Locomotive was transported by ferry from Tallinn to Helsinki and then by truck transport to Minkiö depot. Locomotive was unloaded from truck roller to rails by two heavy cranes. The first test runs were driven almost immediately at the same day.

In Museum Railway the locomotive is used primarily for maintenance purposes and wagons shifting in marshaling yards, but also in a museum trains. Locomotive is equipped with turbocharged engine generating 260 horsepower and a top speed of around 50 kilometers per hour, so it is well suited to heavy freight trains and faster passenger trains.

At the Jokioinen Museum Railway there are two operational Move 21 diesel locomotives. Third of the series is under renovation. Locomotives were built in 1948.

There were total of 76 Move 2 diesel locomotive built after the World War II in years 1946-52. Locomotive were built as war reparations for the Soviet Union. All the locomotives were four axle locomotives equipped with a wood-gas generator which produced carbon monoxide from the wood to power the combustion engine of a locomotive. Of those 76 locomotives 10 stayed in Finland. Valmet Oy replaced their engines to normal diesel engines and change their type to Move 21. Those locomotives were sold forward to an engineering firm Saalasti, which was trying to sell the locomotive to various Finnish narrow gauge railways. The machine shop of Turenki Sugar Mill rebuilt five of the ten locomotives to broad gauge.


The locomotives number 1 and 3 were originally in use at Loviisa-Vesijärvi Railway from 1956 to 1960 and after the railway was rebuilt to broad gauge the locomotives were sold to Jokioinen Railway. The locomotive at Jokioinen Museum Railway without number  was originally used at Hyvinkää-Karkkila Railway from 1954 to 1967. Jokioinen railway bought this locomotive in 1967. Originally green locomotives were painted orange in 1970. There were total of four Move 21 locomotives at Jokioinen Musuem Railway (numbers 1, 2, 3 and the one without number "Karkkilalainen").

Number 1 was in use until 1972 and was bought to Jokioinen Museum railway in 1972 in very bad condition. The complete overhaul of the locomotive started in 1989 and it has been advancing slowly when there has been time of all the other work.

Number 2 was scrapped in 1968.

Number 3 was used at Jokioinen Railway until the railway was closed down in 1974 and after that on trains dismantling the track in 1974-75. After the track had been dismantled the locomotive stayed at Humppila from where it was transported by a truck to Minkiö after Jokininen Museum Railway bought it in 1976. The locomotive was out of service in 1979-86. In 1986 it was painted back to original green color. Today the locomotive is in use to haul the heritage and charter trains.


The locomotive bought from the Hyvinkää-Karkkila Railway and the one without number was in use until the Jokioinen Railway was closed down. After that the locomotive was sold to a private owner. The locomotive was transported to Lammi to a short stretch of a track where it ran sometimes. The locomotive was transported to Jokioinen Museum Railway in July 2007. The locomotive is still privately owned, but Jokioinen Museum Railway maintains and operates it.

Scoma diesel locomotive

in 1960s the Nokia paper mills bought two new German Schöma narrow gauge diesel locomotives to replace steam locomotives of their industrial narrow gauge railways. The first locomotive arrived in Finland in 1965 and the second in 1969. The locomotives were used to move the pulpwood wagons in the factory area.

The railway traffic at Nokia paper mill ended in 1972, after which the locomotives moved to  Oy W. Schauman Ab:n Pietarsaari pulp mill. Over there they got their numbers 6 and 7. In Pietarsaari they were in heavy-duty use and in 1976 when the train traffic in Pietarsaari ended both of the locomotives were in very poor state and inoperable in spite of their short service life.

The locomotives were donated to the Museum Railway Association in 1978. After standing for few years without use the locomotives were transported to VR Vaasa shops where the number 7 was fully repaired in operating condition and number 6 was used as a source for spare parts. At the same time the original gauge of 600 mm was widened to 750 mm gauge used at Jokioinen Museum Railway.

The rebuilding of the locomotive number 7 was completed in 1985 and both locomotives were transported back to Jokioinen Museum Railway that same year. After this the number 7 has been used on work trains and switching at Jokioinen Museum Railway. Also the chassis and cabin of the dismantled locomotive number 6 is still existing.

The Christoph Schöttler locomotive shop which build both Schöma locomotives exists today and is still building both normal and narrow gauge locomotives.  Jokioinen Museum Railway has been able to buy spare parts and also to pick them directly from the locomotive shops in Germany.

There are total of five Move 4 diesel locomotives at Jokioinen Museum Railway out of what three are operational. There were total of 17 locomotives of this type built in 1950-59 mostly for industrial narrow gauge railways and railway construction projects. Out of 17 locomotive s11 were built of gauge 750 mm and six of 600 mm gauge.

Because of its small power and light weight the Move 4 locomotives are rarely used at Jokioinen museum railway to pull special trains or light work trains.

Forssa electric railway

This locomotive was the prototype of series and it was used by VR track building in years 1950-61. This locomotive was for example used when the 750 mm gauge Loviisa-Vesijärvi Railway was rebuilt to broad gauge. In 1961-82 the locomotive was used at Finalyson Oy Forssa sawmill. Asko Oy donated the locomotive to The Museum railway Association in 1990. The locomotive was fully renovated in 1995-99.

Olkkola saw mill number 2

This locomotive was with its sister locomotive in use at  A. Ahlström Oy United Paper Mills Olkkola sawmill in 1950-76. Both locomotives were donated in 1976 to Jokioinen Museum Railway.  The locomotive number 2 was used a lot to pull passenger and work trains in 1976-88. The sister locomotive number 1 has been used for spare parts and is today mostly dismantled.

Industrial Railway of Varkaus Factories

The locomotive was used at  A. Ahlström Oy:n Varkaus Factory from year 1951, but was later sold to a private person in the beginning of 1980s. The owner fully renovated the locomotive in Vantaa. Starting from year 2002 the locomotive has been located at Jokioinen Museum railway, but is still under private ownership.
