Orion JR5 steam locomotive

The newest steam locomotive of Jokioinen Museum Railway is a Belgian tank engine built in 1948. Originally the locomotive is used in Jokioinen Railway and it is technically indentical with Jokioinen Railway number 4 "Tubize". In Jokioinen railway it was known as number 5.

The locomotive is named Orion by its former user, Welshpool & Llanfair Light Railway in Wales, Great Britain. The locomotive is built by S.A. Les Ateliers Metallurgiques Nivelles Division de Tubize in Nivelles, Belgium.

JR 5 served in traffic from 1948 to 1964, when it's boiler corrupted and it was stored in Jokioinen in temporary shed made around it. In 1972 Malcolm Knight, a steam enthusiast that worked on steam engines as a draftsman and fitter in his younger years before a long and highly respected career on the railways in the UK bought the locomotive and transported it to Great Britain. Later JR5 was rebuilt back in running condition on Welshpool & Llanfair Light Raiway museum railway. Orion served in WLLR museum traffic a couple of years, but rapidly emerged that JR5 was too big and heavy for such light-constructed railway.

When Jokioinen Museum Railway asked to buy JR5 back its original home railway, the WLLR suddenly agreed. The final contract was made in autumn 2006 and locomotive was transported back to Finland. Orion moved first time in Jokioinen Museum Railway in October 15th 2006 (see video below).

Despite Orion is located in Museum Railway, its owner is a Finnish private person.
