I did check for shorts across the tracks after I disconnected the CSs. Also checked my work to see if I got cross eyed and connected the wrong track lead. No problems in any of these. I checked the loconet and it is all working fine. I tested it by removing the batteries from the DT100 and operating a sound loco from each of the five UP5s, the UR90 and the UR92.
I had four locos with sound on the track when this occured. Two were BLI locos with sound a Kato loco and an MTH, all with sound. I tested each of them for damage and luckly non were effected.
