This blog was originally written in 2019. I’ve revised it now in 2022 as the news has broken that the Southern Class 313s will be retired in 2023, so catch them whilst you can.
Whilst the BR designed Class 313 EMUs have finally been withdrawn from service on the Great Northern routes out of Kings Cross and Moorgate and headed off to the scrapyard 19 of the Class still hold out on Southern metals, working ‘Coastaway’ services centered on Brighton. Numbered 313201-217 and 313219-20, the units were converted and renumbered from former Silverlink Class 313/1’s that had been used on the North London and Watford DC lines before being displaced by the new Bombardier Class 378s. The 313s were refurbished at Wabtec, Doncaster where they received alterations to the seating and a Passenger Information System, but no toilets, which has proved controversial as they replaced Class 377 units which did have them fitted.
The units began operating on Southern from the May 2010 timetable change, working Eastwards from Brighton to Lewes and Seaford and West to Littlehampton. They even operated as far afield as Portsmouth in the West and Ore in the East.
The Covid era saw various services cut which have never been reinstated so the need for the fleet decreased. Nowadays the only Easterly diagrams are to Seaford and Newhaven Harbour. All other diagrams are westwards from Brighton to Hove, Littlehampton, Barnham, Bognor and Portsmouth.
The very useful ‘Part-Time spotter’ WordPress blog publishes a list of the diagrams here and also supplies daily unit allocations. Why not give them a follow? There’s currently 13 diagrams for the 19 strong fleet.
Here’s a selection of images showing their area of operations.






















I’ve a small favour to ask…
If you enjoy reading this or any of the other blogs I’ve written, please click on an advert or two. You don’t have to buy anything you don’t want to of course – although if you did find something that tickled your fancy that would be fab! – but the revenue from them helps me to cover some of the cost of maintaining this site (which isn’t cheap and comes out of my own pocket).
