313 smoking?! - Bishopstone - 16.5.2015

The 313 class are electric multiple units (emus) that used to be used on inner London suburban routes. When no longer needed there, they were transferred to the south coast, where they run between Brighton and Seaford to the east and Brighton and Portsmouth to the west. The latter is quite a long journey for a train with no toilets!
Suggesting that the passing cloud gives the impression that the electric train was making smoke or steam, is just one of my whimsical moments!
