Having said that I wouldn't wish to diminish the excellence of this program in any way - it really is superb. It may also be useful as a training aid for professional railwaymen, as it demonstrates traffic regulation and the effects of out of course working - just stop a train somewhere in the central section and you'll see the system gradually grind to a halt. Then watch what happens when you start it again. Mileages are shown with the electrification route references. The letters shown in brackets beside signal cabin names are the prefix letters which appear on their colour light signal posts.
Additional services run in peak hours.
If you alter the clock time you may find a number of 'loose cannons' rolling around because they haven't been recalled to depot. If I was starting again from scratch I would have used more vertical space, but I originally intended to include only the electric lines, and found the construction so much fun and the layout so evocative of its time that I had to add more and more to give the right flavour to the simulation. Everything in the layout is interdependent except for the trams and the dockside shunters, so be very careful if you add or alter any trains. I've put in a number of trailing crossovers to help with sorting out any problems, but remember to reset the signalling if you use them. Thanks also to David Young of Railtrack Scotland for his help and advice.
