| With the current system, if the train goes past a signal at red - even after approval from the controller, it will have the emergency brakes applied, and after resetting it, is restricted to 5mph for a period of time afterwards. The only way to do what you sugggest would be to disable part of the system and stop the automatic braking of trains. What if the GPS transponder on the train in front of you has failed and you have turned off the automatic emergency braking system? No-one in any position of responsibility is going to sign off on something that makes the railway less safe. It would also be a very costly thing to do. You couldn't do it in an uncontrolled fashion. You would need a record of what you had done, and which signals had been modified. You would have to modify lots of drawings at significant cost, especially as a lot of the drawings probably aren't on a CAD system. Then you would need to add the actual cost of going to site and physically modifying the systems - which is not a trivial job. For all of those reasons, it's a total non-starter, but there would be another monster issue to deal with - the trade unions. ASLEF and the RMT would (rightly) not countenance their drivers being put in a position where they could be in a crash. They wouldn't even have to go on strike and lose pay. Staff have a right to refuse to do something unsafe - like drive a train without these protections. |
