Question about speed limit signs?

[sfinlay]

How do speed limit signs work ? There is nothing in their config files to indicate how they work and I've not seen any related scripts with these assets, so how does a loco know how to interact with them and more importantly, how can someone create one ?

Actually, there is. They are of a special KIND asset called "Scenery-trackside" and have a tag, speedlimit, expressed as meters per second.

When a loco in a 40 mph zone encounters a slower speedboard it slows to that speed, when the rear end of the train encounters a higher speedboard (than the previous slow speedboard), it only then speeds up, when the tail end passes that higher speedboard.

So if you have a 5280' train that encounters a 10 mph speedboard, if you measure back with a ruler 4000' and place another 40 mph speedboard, your train will slow for 1280', then it will speed back up to 40 mph, once the last car passes.

Easy to remember:

Down speed (decreasing) = first loco
Up speed (increasing) = last car
