Thanks very much.  I have my original DC unit so will give it a try.

I use the Bachmann E-Z Command ® Digital Command Control System and I am trying to understand how I might control low voltage lighting (crossing signals, etc) with this device or do I need another source of power?

Thanks to everyone for their replies.  Just something about knowing the tricks of the trade that save enormous amounts of frustration.

Thank you very much.  When all else fails...Google.

Could someone tell me how to determine the optimum weight for rolling stock?  Sometime ago , I found a formula that calculates this weight for maximum performance, but I cannot locate it.  Thanks.

Thanks for the tips on this.  Looks like the sale of this locomotive is imminent! Thanks again for responding.

It came as part of a train package from Bachmann named the Overland Limited. The engine is a Union Pacific 4-8-4.  I don't know how else to define it.
Thanks for getting back to me.

Is it possible to convert a 4-8-4 from DC to DCC? I purchased this steam loco as part of a set and now wish it were DCC.  Any help appreciated.

What is meant when something is specified Standard Pack of ....?   

I am new to DCC and wonder if a locomotive that is advertised as DCC ready needs anything else other that the EZ controller or Dynamis system?

Thanks very much for the prompt reply. Already having fun.

On a piece of Bachmann track such as curve radius 28", angle 18 degrees, what does the 18 degrees refer to. Thanks.

Thanks to all who answered.

Can someone tell me what R-T-R refers to?  Thanks
