This is my first post and I have a question. I just purchased a new 3 truck Shay and put it on the track for the first run to see if all was OK. The engine seems to run fine but it runs much slower (really a lot slower) than the rest of my engines. Is this how an actual Shay engine would run due to its pulling power? Is this normal because of gearing or should I return the engine due to something being wrong. I only have 10 days to make a return Thanks for your help and all opinions are welcome. Due to the cost of this engine I want to make sure nothing is wrong.
