Shoeburyness, my home station for most of the first half of my life to date, is the correct answer. This picture, of Platform 3, was taken during this year's airshow weekend, specifically Sunday 29th May, with me about to leave for Portsmouth. This was effectively a chance shot, because I should have been in Bath - I was only back home because my mother had to go into hospital.
If I used the whole picture though it would have lasted 30 seconds - there is a 357 on Platform 2!
For the record, the only other stations that matched every clue besides the usage one were Southend Central - sorry Matt! - and Upminster, both of which have appeared more than once already. Also, *Matt*, seen as you've been to SRY in the last year, I'm a bit disappointed in you!
