Lumo overspeed incident at Peterborough (17/04/2022)

[Signal Head]

Quite possibly but drivers are trained to expect that the next signal will be held at danger and drive accordingly, which in this instance should prevent them applying power up to 80mph. If they fall into the trap of 'when I get a yellow here the next one is always green' then that is no different to any approach-controlled (or similar) signal anywhere else on the network.

Except that it isn't common to artificially hold an approach released signal at a lower aspect than allowed by conditions ahead until the train passes the signal.

Doesn't matter if it's common or not. Pass a yellow signal, expect the next one to be at danger and control the speed of your train accordingly. End of story.
