I recall (possibly incorrectly) reading that on some lines in the UK, mainline or underground I can't remember which, the driver is only allowed to accelerate once the end of the train has passed the speed limit sign.
Why? Would it not make sense to place the speed limit sign where speed can actually increase as opposed to waiting until the back of the train has passed over it?
Is that too simple an idea, and perhaps some sort of safety mechanism prevents this happening?
