OPERATIONAL ARRANGEMENT
I never design a layout and then try to calculate what its operational potential will be - that process will almost always result in disaster. Operational potential has to be factored in from the outset to ensure that trains can move in a fluid, railway-like manner, and even with the smallest layout that there are sufficient holding sections, both scenic and non-scenic, in order to provide variety. Have a look at the accompanying diagram and you’ll see what I mean. It’s a variation of the main plan and there are five locations (four scenic, one non-scenic) for holding a main line locomotive and four coaches, or comfortably accommodating a four-car DEMU. Obviously you wouldn’t want to fill all these tracks with a train or there would be no option for movement. Similarly, the two short DEMU sidings allow for a start and end point for flyover trains or for traversing the lower level. I’ve shown two potential headshunts, on the main line, for the non-scenic curved sidings. You can also use the adjacent siding and graded track at busy times. If you’re following prototype practice, the flyover line should be operated in an anti-clockwise direction, but if you’re running just for fun, trains can go either way and use the lower level in a ‘looped eight’ fashion. Please note most of my comments here apply to the larger layout too. Such a small area will always have limitations, but effective planning will always ensure you get the most out of any given space - it’s a key factor of good design. That said, it’s amazing what a little bit of extra space can offer to an already effective design.
