@LinaBlue @RinaVolpina @kouett @rail That's more like marine phraseology. UK railway telephone protocol would be to pick up the platform telephone and say something like:
> Anytown signaller.

> This is an emergency call. $role $yourname at $location. Someone has fallen on the tracks at platform $number. Please block the line immediately

Not a railway professional but my partner worked somewhere that did e-learning for Network Rail and that was in their portfolio somewhere!
