what didn't work, because at mine it works!!
mayby because i know how it works....
a very important thing is that the pushcar is in TOGGLE mode =
launch by pressing the right arrow SHORT
when the train is away, press the right arrow again SHORT to let the pushcar come back..
when he is fully back you can launch the next train... if you only press the right arrow to launch the train and you didn't pressed the right arrow again to let the pushcar come back, it will cause problems to the next train... i hope you see the problem now...?
