I want to let Christmas go a Weihnachtslok back and forth, I ordered the automatic shuttle service and get very quickly. Well, I had no idea what to expect with. The manual is so simply written, that I have understood it. Two separating tracks are supplied with. The settings are a little complicated, because when the two rotary wheel has no divisions and proceed as I am with the motto rotation and see what happens. Took about 30 minutes and I had exactly what I wanted. It's impressive when the train back and forth without having to turn the dial.
