I think that this is the layout that I will eventually build for myself. Everything’s there without the layout being excessively large. This small railroad allows for independent train operation, with one locomotive taking its power from the rails and a second locomotive using the overhead catenary wires. The trains are also controlled by color light signals or semaphores, so a third locomotive can switch the small marshaling yard in the upper right while the other two trains remain in the station.
To be sure, I’ll modify things just a bit here and there, and make sure that the station scene itself is visually isolated somewhat since it is an interesting area. The road in front of the station would be an important visual element, and I would probably have it gently curve at each side of the area in front of the station itself. The yard gets isolated just a bit, perhaps with shrubs and roads. The siding at the upper left would probably be straightened out and made into a container terminal with the 8972 container crane or else make it a petroleum facility to use all those wonderful tanks cars available in Z.
A newer layout book (0294) became available from Märklin in 1992. It has been supplanted by the hard bound 0296, which is in English and is currently available.
