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.

E56396 + E50231 on Scotswood Bridge, October, 2nd, 1982, just before closure of this route. Here Tyne Valley trains crossed from the north to south bank of the Tyne (or vice versa) for the last/first few miles to/from Newcastle. The condition of this bridge was the reason given for sending all trains on the route along the south bank through Dunston. Although with Europe's largest shopping complex opening in the mid 1980s presumably trains would have diverted that way anyway. Despite it's 'condition' the bridge still stands, apparently conveying various utility pipelines. John Carter.

On September 12, 1981, E51301 + E56464 depart Darlington with the 11:55 to Hartlepool. Until the mid 1980s there was an hourly service between Darlington and Hartlepool which used to carry a lot of students to Stockton and Billingham tech near Billingham station. Due the shortage of trains with the shortcomings of the new Pacers, the Hartlepool service was replaced by buses. The service was never reinstated apart from a token two trains each way on a Sunday. John Carter.

E50200 + E56072 / E56378 + E50221, Darlington, August 22, 1981. Darlington based Class 101s were always smartly turned out, contrasting with their Heaton based counterparts. John Carter.

Thornaby was refuelling and stabling DMUs at this time and the nearest set is doing the shunt moves necessary to get on the depot. Thornaby station buildings were demolished soon after, becoming a windswept platform with only a bus shelter for passenger accommodation. Although now much improved with a ticket office and waiting room it is a shame the original buildings hadn't been renovated. John Carter.
