OK LA has 4 Metro Light Rail cars for sale so I will take a bite at this

Turns out Jamestown NY is planning a one mile commuter train or trolley loop to a satlite parking lot for its new National Comedy Museum. If the starting bid is at 100,000 a car I think I can raise some money here. The track would be part using part of the Erie Mainline thru town and a 1/4 mile of new track.

Good luck!

I think you’re too late, bidding on the four well worn, poorly maintained, 25+ y/o, Blue Line surplus P865 cars ended March 3: https://www.metro.net/about/mirss/ But hey, thanks for bringing this to my attention so I can bid next time …

Well there are smaller items like abandoned bicycles left at stations see-http://www.kenporterauctions.com/search_consignors.asp?AgencyId=156
