There are many do's and dont's in life.announce1 For example, DON'T start dating a friend, DON'T spit into the wind, DON'T try to shave around a pimple, etc. Anyhow, I was wondering what are some of the big do's and dont's of Model Railroading in everyone's experience? :mrgreen: In my experience I can say for one, DON'T lay a turnout in a tunnel, EVER. Just a bad idea. Because by Murphy's Law, that will be your most troublesome turnout. If you absolutely must, make sure there is access to it from every angle with pop outs or something.
