Hammersmith & City strike on 13 November
In article , Clive D. W. Feather
writes In article , Andrew P Smith writes (4) The person has an intermittent eyesight problem that doesn't stop them playing a game but isn't safe for something like train driving. For example, temporary blindness in one part of the retina, or temporary blindness in low light. But they can see a squash ball whizzing around a brightly lit white court at 35 mph......... To continue with this one as an example: (1) I said "one part of the retina", or "low light"; neither case would prevent you seeing a brightly lit squash ball in continual motion relative to your sightlines. I didn't realise all tube tunnels were lit. If you can see a moving squash ball then you can see a signal. (2) If they fail to spot the ball once, the worst they get is a clonk from it. If they fail to spot a signal or other hazard once, people can die. Signal is a red herring, I believe you know all about tripcocks. If the drivers eye sight is defective then they will be rumbled at the medical each year and stop driving trains. Sheesh. Do I have to make the difference any clearer? When in a hole Clive, stop digging. -- Andrew Electronic communications can be altered and therefore the integrity of this communication can not be guaranteed.
