Class 313: The first 'second generation' EMU, the class 313 was developed out of the 'PEP' prototype. These were also the first dual voltage 25kV AC / 750V DC EMUs. 64 3-car sets were built by BREL York, entering service in August 1976. The reduced profile, and end doors were necessary for working the Finsbury Park - Moorgate section of the Great Northern inner suburban services for which they were built. The design was successful and perpetuated on the AC only classes 314 and 315, and DC only classes 507 and 508. A 313/1 subclass was for sets with additional shoe gear for working on the Euston - Watford DC and North London Lines, which they started working in the late 1980s. These sets were displaced by class 378s by September 2010. Some units augmented the Great Northern fleet, but from May 2010 19 sets refurbished as class 313/2 commenced work with Southern from Brighton on the 'Coastway' route. From 2013 313121 has been used a test train for the European Rail Traffic Management System (ERTMS) signalling project.
This image was taken at Highbury and Islington, and shows class 313/1 313011 pausing with a Richmond - North Woolwich NLL service. Little did I know that from 2007 this would be my local station. Much has changed, and these platforms would subsequently be used for the re-opened East London Line, whilst the NLL east of Stratford is now served by the DLR.
