Learning trains...

Hi to all,

in my last thread I asked how to do trains. This is now the attempt to do one.
I am also fascinated by these puzzles that you incredible guys allways create. So this is also my first puzzle.

The train is for lvl3+ users and will end on sunday at 8pm (german time). Hop on and enjoy the ride.

I wish you all a nice and sunny weekend. :-)

And as allway: Sorry for my bad english.

and please tell me if the train is broken
