For those who are confused about what engine is pulling the train. It's 190 but dressed up as engine 13. The story behind this is that on the original tweetsie railway (ET&WNC) they were 13 engines numbered 1-14 there was no 13 so people thought that 13 was the ghost train.
They use the headlight all the time, you just dont see it on in town because people complain about it being too bright or the generator wine bothering them.
