Network Rail's Track Assessment DMU Class 950 No.950001 at Ribblehead station. STEPHEN GINN.

Network Rail has confirmed that its two-car Class 150-derivate Infrastructure Monitoring train will be withdrawn and disposed of.

The two-car diesel multiple unit (950001) was built as part of the Sprinter production run of the mid-1980s purposely for use as a track monitoring unit.

It was new in 1987 with vehicles DB999600/601.

Network Rail Programme Manager Mark Chestney told RAIL: “We plan to replace 950001 with a two-car ‘153’ next year.

“The ‘950’ is unique, whereas we now have a fleet of ‘153s’, so much more efficient to have a fleet of the same type of trains.

“Also, the ‘950’ has obsolete technology on board that is no longer supported.”
