Thousand Islands Railway 500. This is the only photo I've seen of it on display. I think this was once an electric steeplecab, converted to diesel by owner CN for this short line in Ontario.

We may have had this discussion some time ago on the old board. TIR 500 was actually a gas-electric converted to diesel. If I recall correctly Canadien Locomotive Company built it under a license from Whitcomb or Davenport.
