I'll give that warm sponge idea a try.  Also, does anyone know how to access the polarity switch as well as the on/off switch for the smoke generator?

I recently purchased a Davenport 0-4-0 on eBay, and can not easily pry off the lubrication plug that is located on the bottom of the engine.  I do not have a manual, and was wondering if there is some trick to getting this plug off.  I do not want to use force, as the outer rim of the plug is already deformed by my attempts to pry off the plug with a small standard screwdriver.  Any tips would be greatly appreciated.

Thanks for you help!  I was thinking of something along the lines of the 1:20.3 Scale 2-6-0 Mogul.

I have a couple of newbie questions:

The instruction manual for E-Z Command says that DCC ready trains will run on a DC-controlled layout as long as one doesn't use a feedback type DC controller.  Is Bachmann's Large Scale Power Pack and Speed Controller a feedback type DC controller?  Bachmann's web page says that the Large Scale Power Pack and Speed Controller is not "DCC compatible," but I don't know exactly what this means.

Also, how many feet of Bachmann track can be reasonably powered with the Large Scale Power Pack and Speed Controller?
