New delivery and testing electrics pulling trains through the cascade tunnel.
Surprised as it appears I got a short between the couplers when connecting to the front of the steam engine. With a kadee plastic box, it should be insulated. I turned the engine 180 degrees and didn't see any spark.
Got separate throttles for the electrics so a little cumbersome holding/operating two throttles.
Electric uncoupled and went across the 'cross over' and back to the 'electric' siding.
