>>2019331East Broad Top is a 3' narrow gauge railway. Only a half mile or so of the original 33 miles was dual gauge where it connected with the class I railway. That five mile section that is currently being operated as a heritage railroad isn't part of the dual gauge section. The simply don't have anywhere to run it. I don't know the full story of why railfans from Alabama ended up buying an locomotive that had been sitting on a Pennsylvania storage shed for 70 years, but Red Bay ended up with it because they were willing to pay money for it. EBT wasn't going to have anywhere to run it in the foreseeable future and the railway can use the cash to keep their 3' gauge steam locos running. So, here we are.
TVRM has one of two or three remaining Fairbanks Morse opposed piston diesel locomotives. This one ran hailing coal for TVA until just a few years ago.
