I'm totally new so this may seem like a very elementary question.

I have 2 boys (not counting 1 husband) that want to start model railroading.  They are both getting starter sets for Christmas.  Of course, each boy wants to operate his own train, but on the same layout (we don't have room for 2).  We also are not going to use DCC, we just want to use the controllers that come with the set.   We know nothing about 'blocking' part of the track - I don't even know if that applies to EZ track.

SO, do we need to have 2 totally separate tracks??  We do want it to be interesting, not just an inside and outside oval.  They both want a tunnel and 1 'needs' a bridge.  If this is the only way to do it, has anyone ever seen a track plan like this or have any ideas on where I can look?

ANY suggestions are greatly appreciated.  Thanks!
