Newhaven East Quay branch or the Beach Tramway - 19.2.2013

This view looks from near Tidemills, past the site of the former seaplane base, which was to the left, and on towards the harbour.
This line's main function, in the mid-20th century, was to convey shingle from the east of Newhaven to the west. This and other interesting facts about East Sussex Coastal Railways can be found in two slim volumes by Paul O'Callaghan. The first is about the 'main' Ashford to Brighton line and the second covers branch lines and other railways. I have no connection with the author, but like to credit him with providing the information about this photo and the one of the original Bishopstone station.
I think that the rails, since closure, at least at some places, may just have been used to edge the concrete path, as the gauge looks decidedly 'out', quite apart from the wobbles.
