Well, I just took this track out. After careful observation I noticed each time a train ran over it the circuit breaker light on my TW would flicker on and off and on my shorter engines where I had the e-unit set to work it would stop the train. I suspect I have a defective track. Will try trouble shooting it later. A short may explain why the milk cars work fine when run straight off the TW but not off the track. Now for the next question and lets see if I get any replies on it.
