I have Kato unitrack and DCC. sometimes if I flip a turnout, say, for a spur, and I have a loco on the spur and another on the mainline, it’ll cut power to one of them. Is there some sort of component in the turnout mechanism that’s causing it to act as an electrical switch? Is this on purpose...

Hello, Just a quick question for anyone that runs this radius curve on there layout. What is the biggest steam loco you can run without derailment problems or binding?
