Аннотация
Holmgren's supposition that colour blindness was one of the causes for the train-disaster which happened on 15th November 1875 near Lagerlunda had been passed on as an established fact. The course of the accident is outlined on the basis of the court records. It shows that not colour blindness, but the fact that the engine-driver and the station-master were acting contrary to regulations resulted in the head-on collision with the opposite train. After this event systematic testing of colour vision in railway-men was instituted and the methods of examination were considerably improved.
