Documenting 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 railcar in detail
  • Topics - features articles on differernt aspects of the vehicles and recollections
  • Technology - describes the technical details of how they work
  • Data - various lists of numerical details
  • Images - various 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.

Vehicle Data



It's taken a few years to achieve but all the original written content has now been re-instated here from the original version of the website. Recent additions have had little new content added while I aimed to reach that milestone, but I can now concentrate on adding new material and features.

And as of today (1/1/16) I've so far added the images from the first 50 original 'gallery updates' - 1,780 images. We reached 106 updates originally and these will continue to be added almost daily.


February 6th, 2016

Probably the most important update I've ever made to the website, the new search box above provides details on each DMU vehicle. Additions will be made to these vehicle pages (such as allocation and formations), but this will be a slow process due to the vast amount of data involved!

February 1st, 2016

The minutes of the 57th Lighweight Trains Committee meeting (August 1958) have been added.

January 30th, 2016

A new method of viewing images introduced - when you click on most thumbnails you will now go to an image page with options for viewing larger versions of the images if they are available.
