Here at the ACMU Society we believe in more than just the preservation of vehicles.

We are slowly building up a digital archive of historical records, data, drawings and photos of multiple units past, present and future, aiming to one day be the largest single online database available for AC EMUs.

​

The ElectroPedia website takes a great deal of inspiration from Railcar.co.uk. Please go and look at their work.

We aim to provide a comparable level of coverage on British Railways AC EMUs (a.k.a. 25kv AC Overhead Electric Multiple Units).

​

The six key sections of the ElectroPedia are:

• Types - Looks at each type of Overhead EMU in detail past, present and future

• Topics - Various journal articles related to EMUs

• Technology - Technical Data and information on how EMUs work

• Data - Class formations, allocations, Diagrams and more

• Images - galleries featuring EMUs

• In Print - details the books and other printed materials about EMUs

​

DISCLAIMER AND SCOPE:​

The Electro-pedia is currently Heavily under construction, Paid ACMU Members are able to preview some of the pages. Please note a lot of material is yet to be implemented, and there may be missing or incomplete information. Any volunteer assistance to work on this resource is greatly appreciated.

 

The ElectroPedia covers all Overhead AC EMUs. This includes pre-BR designs, the "AM" First Generation Fleet, plus all other 300,700 and 800 series units.

We cover the period from class introduction through operational lifespan till withdrawal from main-line use, and preservation if this has occurred.

 

We do not cover any AC Locos, DC only Third or Forth rail EMUs.

Images Wanted!​

Do you have photos of any AC EMUs? The more images we have the better we can tell the EMU story and make it more useful to visitors. Please get in touch with the society regarding usage of any material. All material is appropriately credited.
