Generelly, the layout would win alot if the room would be wider and longer - about one meter. Then, I could have realized the track plan more "swinging"and so more naturally, with longer station tracks especially in the upper station. Fot myself - I can't change this anymore, but for the case that someone wants to use the plan for an own layout...

Most problems I have are caused by the old Märklin M track. Perhaps I'm the representative of a minority, but find it was the right decision to take this material which isn't up-to-date anymore out of programe. Especially the failure of many controlling track sections is quite annoying, often in a tunnel. So in newer parts, an electronical circuits (allready described) was used. The M track curved turnouts are well-known for their citical conduct in combination with models of other manufacturers. So I have consequently exchanged the wheelsets of all DC trains. Another problems are the turnout actuators - steering them wtth decoders, they don't switch so powerful because of the decoders' lower swicthing performance. Especially the double-slip turnouts get on my nerves quite often. So it's clear, why I wnat to carry out the planned shadow station with C tracks.

Also the transitions and connections between the parts of the lkayout which can be taken out are problematicDuring the construction, they all have matched very well - after a certain time the layout`s material has worked so much that no connection is matching anymore. In the gorge at the front side I had built all track connections diagonal - so that they were matching in the best way. This hasn't proved successful - I will renew them, this time rectangular. I also consider if track connections can be safely positioned with springs. But I want to do without rail joiners which can be pushed forward.
