Good morning from the USA. So I bought the Marklin 37501 SBAHN train new. I put it on the track, sounds work, train runs well but the directional lighting only works in one direction.

So when the train travels to the left, the white head lights on the train cab operate and the red marker lights on the right side of the train cab operate. When I reverse direction, the lights on the left side of the train switch over to Red but the train Cab on the right side doesn't switch to white, the red simply becomes a lower flicker.

I sent away for a replacement of the light board for the right train cab hoping something was wrong there. I swapped it out and still have the same problem.

So based on the fact that the I am still having the problem and the fact that the normal red lights become a red flicker when the white lights should be activated I am assuming something is happening back at the central car where their the chip and board are located.

Does anyone have any advice?

Thanks Mike. That is what I was thinking but I wanted to see if others had experienced similar issues.

Thanks for the feedback. I will have to look at it when I really have the time to sit down and work on it. It has to simply be the polarity isn't completely reversing when the direction of the S Bhan is reversed. That is why I have the red lights flicking a not so bright red when the white lights should be on.

Mike:

I will have to pop the tops off of the cars and take some pictures. I get what you are saying about the transistors not working properly. I am wondering if they would be on the main board on the center car or on one of the end cars? Each end car as a lighting board. Pictures will be posted soon.
