An extremely novel idea combining an end to end layout which is surrounded by two long running continuous main line loops. The layout allows easy access to all parts as it is of a wrap-around construction. A terminus station is located at each end of the layout, both of which are accessed from either main line at completely different points. The lower left hand terminus station has an extensive locomotive depot plus a turntable. The top right hand terminus station has a large goods yard with sidings that are of sufficient length to stable complete trains. The layout provides potential for multiple train operations such as continual use of the outside loops combined with shunting operations on the inner loops.
