Digital Traction Train Simulator have released examples of the famed Class 122 DMUs known to enthusiasts as ‘Bubble Cars’.

The one-car units, which were introduced from 1958, were primarily used on the Midland Region of British Railways, on branch lines that eventually closed in the Beeching report.

They were not just confined to Central England, with some venturing as far south as the St Ives branch in the South West and working Dundee to Arbroath services in Scotland.

Eventually, the class totalled a number of 29 examples, comprising 20 Driver Motor Brake Seconds and 9 Driving Trailer Seconds.

The class had long careers, and carried a variety of liveries with some units modified to carry parcels and for departmental use.

The last of the 122 Class was retired from revenue-earning service at the introduction of privatisation. Some members of the class saw 40 years of service on the national rail network.

8 units have survived into preservation and are popular with Heritage Railways and passengers due to the visibility they provide through the windows, giving them the nickname ‘Bubblecars’. The units also enable viewing from the seating areas into the driving cabs and out through the cab windows, a feature that many different classes of DMUs had in their early careers.

Over the years, many models of the 122s have been made, and now the class has become immortalised in a digital environment thanks to Digital Traction.

The digital ‘Bubblecars’ are available in four liveries: Early and Late MU Green, BR Blue and Regional Railways livery, and can be bought from Digital Tractions shop on their website.
