I have recently received two Bachmann 2-8-0's new.  I ordered these to double-head ore trains through my mountain range.
They run at totally different speeds so that is impossible.  Both are UP. How do I change the gearing on the fastest one?
Beatrs me how Bachmann can market two indentical locos that run at different speeds.

When I buy an E-Z Controller can I plug it straight into the house voltage or do I need to buy a transformer to supply the Controllers input voltage?
If so what is the Controllers input voltage?
Then do I just connect the Controllers output directly to the track to run my DCC 'on board' Consolidations?
And Yeh! I'm a babe in the woods!

I'm confused about the colour of the counterweights on the 2-8-0.
I bought two, both black.  What colour should I paint the counterweights?
