As I look through various hobby advertisements for Bachmann HO locomotives, both old and new, I see 1) Bachman PLUS  2) Bachmann SPECTRUM, 3) Bachmann STANDARD LINE,  4) DCC ON-BOARD and 5) DCC ready.  What's the difference?  Is STANDARD LINE the original Bachmann mechanism.  How can you tell the difference when buying used locomotives, like the original Daylights and F40PH and the newer, better, units..

I was selling a Rivarossi steam locomotive at a train show.  A prospective buyer asked me "how many hours of service" the locomotive had.  I can't print my reply.  Does anyone actually keep track of this.  If operating a model railroad creates more paper work than my job it's time to quit.

Why can't I get a response from customer service?  An e-mail I sent about a month ago was never answered and I'm still waiting for an answer to an e-mail I sent a week ago.  This is customer service??
