The last weekend session had issues with the DCC tripping for a short while and then cleared up and no issues after that. Today's session had one section of track shorting, but not the whole layout. Got it narrowed down to one car with metal trucks that had been running for years with no issues. The trucks have been changed out and hope that those tripping issues are done.
One other issue was that 80% of the phones went out. Don't you just love electronics. Good news here is that we can still go back to radios if necessary. It does make it tough to continue to get the rest of the upper level ready for ops.
