Some people!!!!!!!!!!!!!!!!!!!!!!! I think they should give them a note in reply. "No worries. When you're dying and in need of emergency help we'll make sure to drive around for half an hour to find a place to park that doesn't block anyone's driveway and so take at least another 10minutes to walk to your house with all our gear before we treat you. You tosser." Grant Darwin NT |

Classic. The truck was hauling two trailers of carrots when it changed lanes and struck the car, the California Highway Patrol said. Truck drags car along highway after California highway collision. Grant Darwin NT |

I think they should give them a note in reply. So you finally agree that blue collar workers can be professional. :-) |

All that's wrong with public transport today. :-( Love it saying if they completely pass out it will stop. Have they talked to a medical doctor about that? Seems to be enough instances of sleep walking and the like that I doubt that design of a deadman will work at all. Tell me our DNA still doesn't have some residual from when we used to sleep in trees and had to hang on. |

The basic concept of the "deadman's handle" approach dates back many, many years. It is very simple, but has a flaw. You press the handle down and push it forwards, and hold it in the selected position. This is all very well when the driver is awake and aware of the situation, but it is perfectly possible for a driver to have fallen asleep and hold the handle in position. I understand this was the required level of driver awareness protection at the time the trams were built - for trams. However mainline stock had moved to various forms of driver vigilance device, in these the driver has to move a control within a certain period of time, which is OK when on a route with frequent changes of speed, or stops, to re-enforce this on routes which require long periods of constant speed running there is a "prompt and response" added to this requirement - buzzer goes off and the driver has to press a button or move a foot plate; in all cases failure to act results in an emergency brake application. I'm not sure if the latter system is mandatory yet for trams. Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |

I can't talk about mainline as no experience, however on the Underground up to & including C69 & D stock it's as you say, press down & push forward while still keeping the controller pressed down. The problem with that is the tension in the spring in the Deadman. For many drivers there were occasions where a relaxed palm was sufficient & in the sitting position, other times one had to stand & use both hands as the spring was too taut, & when you had one of those, you knew you'd worked for your money that day :-( |

...or hang your snap bag on the handle to give you that "edge" when faced with a heavy handle. Not that any driver ever did that - oh dear they did and it lead to a self start on the Pic(?) with the driver stood on the platform!. This was one of the reasons why on the new Jubilee & Northern line trains there was a mainline style Driver Vigilance System fitted from new.

Then that was one dumb driver! Any time I left the cab at a station, the control key was centred. |

It is alleged he was not alone in the practice of hanging the snap bag on the handle, selecting a low forward notch and rely on the door/traction interlock to engage and let the "train take the strain". He got caught when one of the doors on the leading car stuck, he got out of the cab, gave it a kick and off shot the train..... With the modern "mainline" DVS you actually need to "enable" the DVS as part of the ready to move actions - and modern single-stick controllers are not amenable to hanging the bag on the handle - most of them are designed to move into brake by default...

Ah I see, more recent stock then. Couldn't happen on the older stock. There was only 3 positions - Forward/Centre/Reverse. One had to press down on the controller, select key position then wind up the controller. Letting go of the controller in any position other than centre operated the deadman. |

It wasn't for that reason. I sometimes did that as well. The controllers them days often had a smooth wood circular top & with the heat, one's hands would sweat. |

...the self start was on a 73TS, so I would have thought a very similar control logic, but then tube and sub-surface did have some "interesting differences" (in addition to the obvious one of size) Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |

I wouldn't know about that stock. I only have experience with 38 stock (Bakerloo) A60 & C69 (Met & Circle) 59/60 (Central). With the exception of C69 which had braking & motive power all in one handle, they were mainly like this |
