One of the loops on my layout will not allow me to switch track sides when using an MTH lock-on. Power works only on one side of the Realtrax section. The lock-on light goes on, but no power to the track. I tried several tracks on this same loop and had the same results. It's not a problem on the remaining loops, e.g., I can use either side of the MH Realtrax and the lock-ons power the loops. I can't figure out what's causing this. I moved the power bricks to different channels and still had the same results with the same loop, one side only. The layout and bricks were tested and they are in phase. My layout consists of 3 loops joined together via crossovers. I'm using a TIU with a Z-500 brick for power and three Z-1000 bricks for each fixed channel, (I changed one of the variable channels to fixed). I would very much appreciate any thoughts as to what the problem could be, and suggestions on a remedy. I posted this earlier, but I believe I may have lost it before entering. If it shows up twice, my sincere apologies. Thanks in advance for any thoughts on this matter. Best, Lou
