Thanks for the advice guys, I appreciate it.  I will be going with HO scale.  The pictures are great and really show there is no limit to what you want to do no matter what size.  Another quick question, I noticed on some pictures there was styrofoam or another material on top of the plywood, is that the best and/or easiest material to make tunnels, mountains, etc. from?

Hello everyone!

I am looking for some advice to get started.  I have 2 young sons who are really into trains right now and am hoping this can lead to some special time for us for many years.  I remember having a train set when i was younger and I had an uncle who had a huge layout in his basement but I don't have much background.  Should I be investing in a DCC system right away instead of upgrading from a DC in a couple years?  The Bachmann Digital Commander has been recommended on some websites as the best way to start out.  If I go with EZ track do I have to stick with that for my layout.  If i add lights does the dcc controller run those? I'm pretty good with making things but wiring I am a novice at.  I have an unfinshed basement that i plan on setting up in.  I have plenty of wood/lumber to make a table.  I would like 3-4 trains to start out, any ideas on size of layout?  Look forward to any and all suggestions.  Thank you.
