One small error I've spotted: 10/442s are shown with a length of 115 metres. So either the length is off, or they're in fact only 5/442s  .

Well spotted! You win the prize. Yes I appear to have had a "senior moment" there, they should be 230m. Appologies Noisynoel Log in to reply |

I was just wondering whether the defensive driving rules are really implemented correctly the way they are now? At the moment, SET trains are to reduce their speed by 50 % after passing a double yellow, and then to 25 mph after passing a single yellow. However at lower line speeds, this leads to some absurd situations. E.g. at 30 mph, trains would slow down to 15 mph after passing a double yellow, only to accelerate back to 25 mph after passing the single yellow (and then slow down again to 10 mph on approaching the red signal). Hoping that the real world policy is a bit more sensible than that, a more appropriate formulation in Simsig terms might be: Line speed 0 - 70 mph: reduce speed to 35 mph at double yellow Line speed above 70 mph: reduce speed by 50 % at double yellow A similar problem applies to the FCC rules. At the moment, those use a percentage-based approach across the whole range of line-speeds, which in low-speed areas can lead to very low speeds, like 5 mph in parts of the Thameslink core. Again, a more sensible formulation might be: Line speed 0 - 45 mph: reduce speed to 30 mph at double yellow Line speed above 45 mph: reduce speed by 33 % at double yellow Line speed 0 - 60 mph: reduce speed to 20 mph at single yellow Line speed above 60 mph: reduce speed by 67 % at single yellow Note that I've just guessed the transition speeds from percentage based to absolute speed reduction, but you should get the idea of what I mean.

This has already been altered and will be more realistic in the next release

After having played through the whole timetable, here are my observations:
