Well, I'm the first one to post a picture, so hah!

Being originally a Londoner (although now living in the provinces), I thought the environment looked familiar.

Photo is likely from early to mid 2000s as the clock, overhead cables warning sign on train and electronic displays are relatively modern. I wonder if the artist did have an interest in trains, as thats the exact place a trainspotter would pick (and even in 1990s when I lived there I remember they would make special journeys to get photos like this)

Maybe we *are* exotic, to someone from elsewhere.

Cup of tea, anyone?

looks like a Sprinter and destination blind says "Gospel Oak" which is just North of Camden Town (so the photo must have been taken quite some time before 2019 as 150128 is since shown as transferred to the railways in Northern England)

I'm not a train expert either but was intrigued as I'd expected rolling stock from somewhere more exotic (or at least on the European mainland!)
