Ok, I am a new at this so please bare with me. I have just completed my layout. I have four lockouts, two for my sidings and two on the straightaways in the front and in the back of my layout. A week ago the whole system was running fine! Going backwards forwards, whatever. Now when I use my Lionel M-7 LIRR set it shorts out the system on the corners of my layout. Now I have run just the motorized car and its been fine! Runs great by itself! It only happens when I have the rest of the 3 passenger cars attached that it sparks underneath makes a click and pop goes the built in circuit breaker on my Z1000 transformer. Now when I run my weaver RS-3 Diesel all is good! Its only happened within the last 24 hours of usage that this is happening. I have a few of my own theories but I figured I better ask the pros on this forum. Any help anybody could offer is greatly appreciated. Now also I have the switches powered up separately to the external power supply attached to the Z1000. I do have some lights running but that is attached to its own transformer that came with the Lionel M7.
