Hi everyone, my 5 year old son is a train fanatic and has forced me (Not really) into getting his first train set about 4 years ago and it has grown ever since. I decided to go with my own design of a layout not mirroring any of the real RR out there. I have to admit I have not done my homework when it comes to the track (the most important I know) . I have a 4x21 double track layout now and it is riddled with problems but the scenery looks so good I don’t want to trash it. I have a few questions that may be mind blowing to you guys but trust me it’s out of not knowing. I hear talk of multiple power sections, I have a command 2000 setup and how do you do this? Just take the main power and section it to different areas? Also I have a river coming across it and I bought 2, 2’ span bridges about 2 months ago. I’m a scenery guy and with the discussion of large body’s of water looking good and staying that way is a huge discussion in it’s self, so here I am looking at a 2'x4' piece of ply wood all boxed in pretty like and I am scared to death to try anything in it? I need help!
