[quote=GUEST76218,435965]It is not a matter of a driver calling anyone. Modern signalling systems work by computers or electric current detecting trains and not allowing following trains to come within a safe distance of trains that are ahead. A basic principle of their safe operation is that if they loose power they are supposed to fail to a safe mode EG following trains will be stopped. In Australia certain regulations allow for emergency operation of trains under verbal advice of signallers when this situation occurs but they travel at a very reduced speed under control of the driver who can only go at a speed at which he can stop short of the distance he can see. Without knowing the results of the enquiry this is the only way I think that the accident could have happened.[/quote]
