Also regarding Superbass, these are Lionel dummy locomotives (often B-units and typically without motors) with enhanced sound capabilities (Fat boy speakers, more powerful audio amp, and baffles).  The lack of motors and associated drive circuitry is the main reason they cost less.

You may want to try dealers on line first. York may not have the engines you are looking for.

I tried looking at dealers but could not find what I was looking for.I figured I'd look in York, if nothing I can always look at dealers again. Thank you.

If you are going to York and like now, it's close to the York meet, always wait and look at York.   If they have what you're looking for it will most likely be at a better price.   If not, what you want will most likely still be available at a dealer when you get back.

Exactly what I was thinking Greg. I missed out on one in Allentown Show. A SD70ACe Legacy brand new in box for $485.00 by seconds. You snooze you loose. Thanks for your input Greg.
