choochoopaul posted:The problem, or the lack there of, is the watchdog signal that is missed by your engines. The TIU should be powered up first, then the power supply to the tracks. The watchdog signal tells the engines that they should remain silent and wait for the startup command. The signal is only present for approx. 5 seconds after powerup.
I always have the TIU powered first, then I apply track power.
