Am considering making the leap to DCC when I make my new layout (whenever that may be, depending on the economy), but all of my current engines (steam & diesel) are just DC.  Can I still run them as DC with DCC controllers, or will I have to swap out transformers?  Also, how difficult (and expensive) is it to upgrade these locomotives to DCC?  Most are diesels, but there is one old NYC Streamlined Hudson made by AHM (Rivarossi) that I really like, and judging by the print (and price - $39.98) on the box it's older than I am.  Any thoughts, suggestions or info would be greatly appreciated.  Thanks.

Thanks.  I'll give it a try. 

I'm just starting to get back into model railroading for the first time after childhood, and I am trying to plan potential layouts.  I was wondering if there is any software (or internet program) available for planning a layout that would keep me from having to break out the graph paper, ruler, compass, etc.  I would like to use the nickel-silver EZ-track, but really want to figure out exactly what pieces I'd need (& how much it will cost) before I start to buy.  Didn't know if Bachmann or other companies had something like that where you could virtually assemble w/their track pieces. 

I have some Rivarossi passenger cars, & 18" radius is a bit much for them, so I assume I'll wan to use at least 22" if not 24" or 28" radius curves for the main line.  Other than that, I'm pretty open design-wise.  Thanks.
