Lives depend on archaic signals

Letters to the editor

It amazes me that the debate on the Ladbroke Grove train crash centres on the visibility of signals. It is quite unbelievable that the lives of perhaps 2000 passengers still depend on a human looking out of the window of his 150mph projectile, spotting a 20cm diameter light embedded in a maze of bridges, wires, posts etc, and reacting accordingly? Surely the issue is not where the lights are positioned, but why such an archaic system is still considered acceptable.

Peter Thompson,
