Staying with the theme of recent posts, that of night photography on Southern Region territory, East Croydon was a particularly good spot for available light imagery of the intensive flow of trains that use the Brighton line. The lighting at East Croydon is just right, with the platform lights of Platform 3 below the roof level of the train. Those on the platform on which the photographer is standing (me!) are not causing too much reflection on the side of the train. The picture is of a ‘4 Big’ slam door EMU working a fast Victoria to Brighton service calling at East Croydon only (headcode 4).
The second picture, taken on the same wet evening, is a Class 319/1 dual voltage EMU in original condition. It was working a fast Bedford to Brighton service which calls at Gatwick Airport as well as East Croydon. Note the pantograph vehicle which enables the unit to operate over the 25kV AC electrified Midland Main Line north of the Thameslink tunnels which link the third-rail network south of the Thames with the 25kV AC OHLE line to Bedford to the north of London.
