Rick - on Tuesdays at Lichfield Trent Valley there are 20-30 of seemingly normal grown standing about on the platform at around 8pm (I go there for me train tickets for the next day). They get all excited when goods trains go by - I presumed it was because they are carrying something in particular - but is it because of the actual train part? I did think it was funny when one of them started bringing a motorhome down and they were all having brews out of it!
Here you go Ricky, thought might enjoy this link for the NSW Rail Transport Museum. http://www.nswrtm.org/ We've had a couple of runs up to it over the years & everyone loved it.
