I just built a small HO layout using (gasp!) cab control. It has 4 blocks on the main route. Cab 1is a Tech II 2400. Cab 2 is an old MRC throttle pack model 3. Blocks are totally isolated and cab selected via DPDT/CO switches. <br /> <br /> Everything works fine except on the 2nd block. If Cab 1 (tech II) is on and I change the direction switch, it shorts/overloads. This doesn't happen on any other block, nor does it happen using cab 2. It occurs even if the block is empty(nothing on the track)! Like I said though, the problem doesn't occur under cab 2 control or on any other block. I'm lost as what to check.
