Some model railways are operated somewhat chaotically and are characterized by frequent derailments and locomotives that stop arbitrarily. If you wish to move away from this kind of layout and construct a model railway that operates realistically and reflects more closely the way that railways actually work, then this is the book for you. Whilst constantly emphasizing realistic operation, the book covers layout planning and construction, controllers, point motors, power supply, cables and connectors, ways of operating traffic flows, signalling, track droppers, control panels and wiring, control and interlocking, lighting, sequence and block bells, the use of closed circuit television, and much more.
