The history of First Generation DMUs


The Railcar website provides information on the British Railways first generation DMUs (a.k.a. diesel multiple units / railcars) introduced in the 1950s.

The six key sections of the website are:

  • Types - looks at each type of DMU in detail
  • Topics - features articles on differernt aspects of the vehicles and personal recollections
  • Technology - describes the technical details of how they work
  • Data - various lists of numerical details
  • Images - galleries featuring DMUs
  • Books - details the books and other printed materials made available over the years that have relevance

Details of railcars in preservation can be found on The Railcar Association website.

DMU Images Wanted!

Do you have photos of First Generation DMUs? The more images we have the better we can tell the DMU story and make it more useful to visitors. Images can be loaded directly onto the site - just register as a user and upload! Alternatively if you have images on flickr or another website I can do the uploads for you - just let me know.


Scope

This website contains details about the First Generation DMUs. This includes the 4-wheel diesel railbuses, ACV / BUT railcars, the Battery Multiple Unit (BMU) and Blue Pullmans. It covers the period from their introduction to British Railways in the 1950s till their withdrawal and disposal from main-line use, but NOT preservation.

Because of the vast amount of data that this covers and the amount of information I have still to process I cannot include the DEMUs introduced on the Southern Region in the same era, nor Second Generation or later types.

On This Day:

114 DMU

Wednesday 16th December 1981 began very foggy, there's also been some snow and it's frozen hard. A two car 114 DMU emerges from the fog at Mountsorrel Sidings, Barrow upon Soar working the 1230 Nottingham - Leicester local service. These were great units, based at Lincoln with extremely good heaters & a nice long 'bed' in their 3 + 2 seating arrangement although the blue check upholstery fabric could chafe your face so I always tried to sleep on my back.
