Video 4, a double 7755 with 20 Shell 7816 at 12v.

Made this video few years ago at mine old lay-out to test if a long train at 12v can work. Made a double 7755 both with 2x 12v motor and 20 Shell wagons 7816 behind it. I was happy with result, only one disavantage. Mine layout was filled with a train.
