I just posted the same issue with my semi scale hudson. I also have a turbine and it runs fine and doesn't get hot. I am using the MRC dual power transformer which does put out the sine wave not the chopped like the CW-80. Hopefully someone will figure this out because I really like this engine.

I lubed it up per your instructions and that seemed to work but after about a half hour it starts to slow down and then stops. I check the moter and again it was too hot to touch. Is there anything else I should do or should I just take it to the service department?

I'm not sure if anyone else is having this problem but when I go to service either of my 2 William's steamers, a O-27 Hudson and a Turbine, I am having problems getting the shell off because of the wires for the smoke unit and the headlight. I had to ducktape the wire for the headlight for both of these and one of the wires to the Turbine's smoke unit came out and I am going to need to take that in to get fixed. Is there an easier way to do this?

I recently bought the o-27 Hudson and the reverse unit will NOT work on my CW-80 transformer. I also have a Willimas Turbine that the reverse unit does work. Not sure what the problem is but when I use an old KW they both work fine. I am just hoping the Hudson works with my MRC Dual transformer since that is what I use on my Christmas layout.

I recently bought an O-27 Hudson and was giving it a break in run. After 20 minutes the engine felt very warm and the motor felt almost too hot to touch. Is this normal. I also have the Williams turbine and it never got that hot.
