There can be no railway line without planning - this applies to both the prototype and model routes. But what other considerations play a role when planning a model railway? Is a double-track main line sufficient or are additional branch lines needed? What topic should all of this be under? In these two volumes (the second volume is the title under order no. 522/71711) everything from the planning and conception to the procurement of materials and the implementation of the system is examined. An absolute must for every model maker!
