My tracks are straight and true, but when I make multiple junction, they go all wavy! Example: Switch yard (hump). I have tried all that i know and looked around but still need help in learning how to make good (multiple) junctions. Youtube video would be great as I learn alot by watching, but any help would be greatly accepted. 
Thx.
