I'm currently playing with the defensive driving rules in relation to unfitted freights. what I am attempting, is for the train to reduce to around 10-15mph well short of a signal, having passed the previous signal at Yellow. I have acheived that, however i was wondering if defensive driving rules can force a train to stop further back than the 18m sim default from a signal at danger. unfitted freights often stopped a lot further short of the signal due to the danger of the trains weight Jolting the loco past the signal. If i was to apply an approach to 0mph - distance 25m, would this force the train to stop further short? equally would the train ever actually move again if it could could see a proceed aspect moving forward?

I never witnessed unfitted-trains stopping short, because they didn't, when I was a signalman but I have witnessed a lot of trains stopping short, these days. If the brake-man (guard) was good at his job, he would keep the train taught, when slowing down. The guard is in charge of the train, that's why the signal was not replaced to danger before the end of he train, which would have been the brake-van.Mind you, in my day, the trains kept moving!

I've got the video evidence and drivers testimony to conclude this did happen. Signals are replaced to danger behind the train for 2 reasons (insofar as I understand). 1.) to ensure all crew see a clear/cautionary signal to avoid confusion with them assuming the signal is being replaced in an emergency. It applies to Bankers as well as the guard. 2.) as a result of a head on collision at Hull Paragon, it became the norm. the incident occured when a signal was replaced behind the loco rather than the tail vehicle, and in doing so this allowed points in advance of said train to be pulled in error, directing it into the path of an arriving train. had the signal been replaced behind the tail vehicle, the train would have occupied the fouling bar on the point and prevented the accident.

Yes. I had TC's, so the points could not be moved with the signal being replaced to danger.

It's a long-standing rule, albeit applied with varying degrees of 'flexibility' and with a couple of official exceptions, that a stop signal isn't replaced to danger until the whole train has passed beyond the signal and any facing points protected by it. I'm not sure whether the rule came into being as a result of the Paragon accident or whether it already existed but was ignored - either way, it certainly demonstrates the importance of it where facing points aren't locked by a track circuit (but still applies everywhere on the national network, except where signals are replaced automatically by the passage of a train, obviously).

I remember in my days as a Fireman at Woodford Halse the Driver telling the Guard to leave the b*****y brake alone. Aubrey Log in to reply |

I believe the automatic replacement of signals as soon as the train passes it caused some issues in certain situations when TPWS was introduced. The one I recall seeing mentioned was banking locos for Kettle-exs out of (?Victoria), where by default once the signal replaced as soon as the front of the train had passed it then the TPWS would be reactivated and the banking loco's brakes would be applied as it approached the signal that was now at red.
