TRAIN FIX

Idea for a film?
Due to series of natural disasters a train across the steppe finds itself cut off and stranded in the middle of nowhere. The passengers have to try and survive out in the wilderness and eventually make contact with local nomads. Gradually the stranded train becomes the centre of a small town, with the still functional train as its centre and power source. By the time the railroads are repaired, a whole new settlement had come into being and when the train finally goes without its passengers, who have a new life in this new town.
