Until next time... Can't get a job involving safe-working on any railway - not even a tourist (preserved) line. I suffer from blue-green colour blindness. It is usually called "blue-yellow", however that term is highly misleading because no-one with the condition has much difficulty distinguishing between blue and yellow. There are no safety implications, thank goodness, and at work I am able to avoid situations where it might become a problem. |
