Hmm.
It seems to be a generic (and apparently not copyright) image: a google search brings up examples of exactly the same image being used on a few Spanish and various other European websites - all non-specific illustrations for some vaguely railway-related articles / blogs.
Thanks, Chris ... I hadn't done such a search. One of my favourite image-finding websites is Tineye (
http://www.tineye.com/) and that lead me to the same image in Perth, Western Australia -

It ain't Bognor Regis, for sure
