Caption: I was always a joy to snoop out Niagara Falls, and particularly Fort Erie in search of the foreign visitors and the odd locomotives passing thru. This one was a real surprise. It is a GMDH-1, according to the Spotters' Guide one of only 4 built, between Dec 55 and Oct 1959. It laying over on its way from South Amboy NJ to Hudson Bay Oil & Gas, about 125 miles NW of Edmonton, Alberta. Despite this transfer happening 32 years ago this month, I understand the unit is not only still operational, it is still there.
