Hi, I'm building an n-scale layout on a door, and I have a couple of questions before I begin: 1) Do I need to solder the track, or is that overkill on a fairly small layout? I'm just using regular code 80 snap-track for this attempt. 2) I have two new Lifelike/Bevbel CPR F9 (or F7, they seem to be some sort of hybrid) locos. I've heard these are fairly decent, but are they anywhere near suitable for realistic operations? 3) I also have two MRC Railpower 1300 power packs. Will these have enough juice? Thanks for your time!
