Diesel multiple units

From the late 1950s diesel multiple units (DMUs) started to replace steam traction on Britain's railway network. By 1968 the transition was complete and these multiple units could be seen throughout the UK from humble branch lines to busy commuter services. In turn these early DMUs have been replaced by the modern versions we are all now used to travelling on.

Fortunately you can still experience the pleasure of riding in these 50 year old units on the GWSR.

  • Driven on each bogie inside axle. Strictly speaking a 1A-A1
  • Built locally by Gloucester Railway Carriage and Wagon Co in 1958, these units served lightly used lines, initially in the Midlands and Scotland. Towards the end of its life W55003 actually worked over our line. The nickname 'bubblecar' has its origins in the very small, one or 2 person 3-wheelers being imported from Germany around the time of their introduction.

  • 64 feet
