I am assembling the stuff to put up a 3'x7' layout in n scale. I was going to have 2 seperate 49" ovals(11 1/4" radius. 1 would be at the bottom left of the board, the other at the top right. They would overlap twice and I was going to handle each cross with a graduated pier set. However, I found that I had a 90 degree crossover and a few pieces of 1/2 curve track. I tried assembling them and they seem to work physically as an at-grade crossing. My question is: Being I was going to use a rerailer and speed control on each oval, will this work electrically? If not, what can I do to fix it? Thank you.
