sweet thanks abc because I want to get the Bachmann Pere Marquette 2-8-4 ... I'm just gonna have to go a little bigger than 4x8 to have more than one line

I have searched around but can't find out what the radius is for the spectrum express santa fe set

thankx for the replies abc ... is there a first train track pack that has 22in radius curves

ok so if I get the a fore mentioned set and get the e z command separately , is it plug and play and I assume it comes with program instructions  also the steam digital commander comes with the e z commander that will control other dcc engines?? One more thing...If I also get your first railroad track pack, the switches it comes with are electric remote that can be controlled by the ex command too or are there seperate buttons that switch them? Thanks very much for answering all my newb questions as this is for my 4yo and me for Christmas. He is a train NUT. One last thing , we are trying to get the Pere Marquette with dcc on board to mach up the polar express in ho scale , I think the engine is item number Bachmann 50949 painted and unlettered ... so my question is what is the turning radius of this engine ...will it work on the 18in radius of the track pack or will it derail? Thanks again, Scott

Just wondering if the Bachmann Spectrum Explorer Santa Fe 1308 comes with the complete dcc system as far as being able to control more than one loco ... it says dcc on board , does that mean the loco is set up to run with dcc or is the dcc controller in the box so you can get other engines on the same track and control them also or is there something else to buy
