Im not an expert but I would say red  is + Black is -   It should all be universal when it comes to wiring

Scott, I take it from your original post that these two locomotives did not always run slowly.  This makes me wonder if the track has somehow got narrower or if the wheels have got farther apart.  The latter is possible with the Anniversary issue 4-6-0's.  It happens when the machine screws holding the wheels onto the axles get loose.  Usually, the wheel also becomes wobbly.  These screws are in the centres of the wheels behind a cover.

I have a Big Hauler that does the same.  I took it apart and there are no screws to tighten to bring the back wheels closer.  Is this for the Ann ed only. 
Where should I apply the oil?

I have the same problem with my Big Hauler.  I know the wheels seem loose.  Will have to try that.  What kind of lube is goos to use?  Anything from a hardware store?
