I remember watching this video a long time ago and still love it to this day. The mini figures looked exactly like the characters from the movie ^^ I did wish you made a Lego Jaws 2 stop motion. Not sure about jaws 3, nor jaws 4 the revenge, we all know the 4th sequel is bad. By this is still a wonderful stop motion :D
Nice video, very interesting, I do alot of shunting at Whatley Quarry and I honestly didn't know this was the original route to there. Steel sleepers are quite common in the UK and the items that hold the rail in the chairs are called keys. Also the building you went into is (I think) an old shunters cabin/ store as I recognise the round things on the floor to be rubber coupling shock absorbers for wagons, you can see them in use on the guards van chassis.
I think you will find it's an ex LMS brake van, it was at Radstock, with the Polish loco and was complete and in pretty good shape, think it was burnt out after the track gang left it their, never recovered...
