I've recently started working on an N Scale layout and I've got a couple of questions I'm hoping someone could answer for me:
1) What is the smallest radius on a curve that is usable? I see that Kato has an 8 1/2 inch curve. I haven't seen anything smaller than that. I'd like to do something tighter than that if possible. Would I be able to build an curve smaller than that with flex track? Would the trains run effectively on it?2) Most of what I am using now is EZ track (because my initial set came with it). I'm reasonably happy with it but I'm having a terrible time with the turnouts. I never know from one minute to the next whether they are going to work when I throw the switch or not. I have four of them right now and none of them works 100 percent of the time. Is it likely I'm doing something wrong or are these low quality parts? Or do I simply have a bad batch (all were bought from the same store within a few weeks of each other).
3) Speaking of 'turnouts', is that what I would have called a switch when I was a kid? Is there some technical difference between a turnout and a switch?4) If I had a DCC system would I be able to have a train on a straight section of track that would automatically reverse direction at each end (i.e. it would shuttle back and forth between the ends of the section)?
I appreciate any advice on these questions.
Thanks.
