Round here we've got the North Yorkshire Moors Railway, which runs from Whitby (where I live) to Pickering. As it's a very photogenic route, it gets used in quite a few TV shows and films;
Heartbeat uses it a lot, and Goathland station doubles for Hogsmead in the Harry Potter films, to name but two.
I've been along the route a couple of times, and took some photos:

Another one, Mallard, is in the National Railway Museum in York, and still holds the record for the fastest steam engine in the World.

Heartbeat, and my Dad (who knows about such things) said to me on the phone, "Repton wouldn't have been anywhere near Yorkshire in the 1960s!"

Seven years ago, I also used to live near Haworth in West Yorkshire, and steam trains on the Keighley and Worth Valley line used to pass on the other side of the lane!
