Ok thanks again. I was infact in contact with First Great Western earlier regarding a similar idea to Bedwyn, and they were not in allowance of arranging a film crew in one of their depots for an idea like this, somewhere in Reading? Due to health and safety which is fair enough, but were willing to perhaps arrange something at a place out of a depot where a train parks for the night. Does this place not do anything like that ever?
If any are interested, the scene is about a man on a train that breaks down, and due to First Great Western being very negative towards us, the inside shots of the train are being filmed in Germany where they have slightly less relaxed laws etc. Budgeting and schedule doesn't allow enough time out there so this why I need to get a location for the external set.
