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.

New DMU photo

From my first-ever roll of railway photographs when I was aged thirteen. A Trans-Pennine unit, complete with Buffet car, runs into Botanic Gardens Depot in 1972. On the far left EE Type 4 399 and Brush Type 4 1996, both in green are stabled. On the far right EE Type 2 8316 is also trundling into the sidings. The photograph was taken on a Kodak Instamatic 25 camera and is scanned from a Kodak 126 negative. Syd Young.

A view looking across to Bristol Bath Road Depot on 5th September 1979. Not the greatest of shots by any means (this is a cropped version as I didn't have a large enough telephoto lens at the time), but it shows the sole-surviving Metrovick Co-Bo D5705 awaiting it's fate. Syd Young.
