Train without a track.

This is one of Sydney's very old train carriages built in the 1920's which were known as the Red Rattler's. They were still around in the seventies when I was doing a bit of commuting in to Sydney and they literally did rattle and roll and of course had no air conditioning in those days. They were so uncomfortable!! 
I spotted this one on someone's property on the way home from Strickland Forest. Not sure what it is being used for but the steps leading up to it make me think that it is being used for something.
