Thanks for the article link, DVC500_at_last. Brought back memories from when I worked at IR in Phillipsburg NJ. It wasn't coal but they had the first diesel lokies for moving condensers and turbines around the plant an onto the mainline. Gotta talk to my dad to get more info. I worked on one of the last buildings and track lines the lokie used in the plant back in '76, he took my kids on the last trip it took thru the plant ~'92 before moving it to the rail museum. I think he was involved in disassembling another one that is in Greenfield Village, MI.
I can still hear that wee-whistle
It's all gone now. Glad I got to be a part of that.
