I though that this would be a Q&A to a real person at the company, not an open board.  I don't know how to be answers this way, but here goes....  I just acquired the HO "Rail Boss" train set.  I don't want to do anything fancy or complicated.  My husband is doing that with his N-gauge set-up, which is getting started. 

I need to know the following:

     1.  As I do not have permanent space for my track layout, how frequently can the "E-Z" track sections be taken apart and put back together?  How many times before the parts start to fail?

     2.  I have the catalog.  It looks like the included track is steel alloy/black roadbed.  What is the difference between that and the nickel silver/gray roadbed?  If you expand, can you mix the two?  Why or why not?

     3.  How many cars can the engine safely pull?  I bought an additional Bachmann B&O boxcar to use with this set.

Thank you to anyone who knows more than I do.
