The British Rail Class 950 is a diesel multiple unit that was purpose-built by British Rail Engineering Limited's Holgate Road carriage works for the British Rail Research Division for use as a track assessment unit. It is currently operated by Network Rail.

It was built in 1987 using the same bodyshell as the Class 150/1 Sprinters.[1] It was originally classified as a Class 180,[2] but was reclassified into the departmental seriesScript error: No such module "Unsubst".. As part of the privatisation of British Rail, it passed to Railtrack in 1994 and then Network Rail in 2002. The unit is formed of two driving motor vehicles, numbered 999600 and 999601.

Current operations

The unit is currently painted in a plain overall yellow livery with Network Rail branding. It mostly works on branch lines, where the track quality is not good enough for larger and heavier track assessment stock. It is able to operate over most railway lines around Great Britain. The unit is based at the Railway Technical Centre in Derby.

Future

In December 2024, Network Rail announced that the unit would be withdrawn and disposed of, to be replaced by additional (modified) Class 153s.[3]
