This... thing was at the CT Trolley Museum. I have no clue what it is or why it is there, but it runs on rails.
I'll refer to it as "failtram" for now.
That is actually LEV2, a railbus from the UK. Built on a Leyland National 2 bus, modify to suit a freight chassis and then exported to the USA, where it has resided since.
There was also Lev1 (Based on a Leyland National 1), Lev3, RB002 and RB004. All of which still survive (and yes, I am making one for Trainz).
Lev 2 was built in 1980/1 (I can't remember the exact year), then it was tested on Old Dalby in the UK, sent to the USA on trials and then brought by Amtrak. When Amtrak used it on a shuttle service, they found it was too light for proper operation and was then donated to a preserved railroad. Later, after a failure with the torque converter (automatic gearbox), a "fitter" tried repairing it and got it wrong, to which, it got withdrawn from service and sold to a scrap merchant.
It was then brought by another preserved railroad, who used it up until 2004 when it went to the Connecticut Trolley Museum, where it has resided since.
However, LEV2 does have a sister, LEV3, that is now in ireland, despite operating in the UK.

This is the power unit of a Baltimore & Ohio Railroad streamliner. I don't think this is so bad. It resembles a doodlebug (gas-electric.)
Thats not ugly, thats functional!
