Hello all,
Can somebody please enlighten me on what's the propose of being able to drop the Deadman/CTBC at 7mph and below with the help of Speed Sensing? (I.E what difference would it make to T/op if he dropped the CTBC at 7mph- or when he has bought the Train to a Stationary halt?)
Answers appreciated,
Christopher.

If you let go of the deadman below 7mph AND have it in Service 1 (D stock) or Rheo 1 & Hold (C Stock) then the train will carry on providing a service 1 brake application rather than an emergency brake application as it would otherwise.
This allows you to let go of the handle just before the train stops and it will still stop reasonably smoothly. However, this is not the approved way of doing things, so officially it is of no use at all! Similarly, the doors can be opened at speeds below 7 mph, but you're not meant to open them until the train has stopped.

Ah!
So thats why i have imagined the doors opening a fraction before the train stops!
It does happen! Its not my mind going crazy!

Was talking to a colleague on the black line recently, who quite literally dropped the deadman!!! Wound up after a signal check and the CTBC came away in his hand! Err, me thinks thats a push-out job... followed by much leapfrogging...

Err, me thinks thats a push-out job... followed by much leapfrogging... Is this the reason why the 92 stock CTBCs normally have a form of sticky tape wrapped around them? IIRC the CTBCs can be slippery pieces of equipment to deal with especially when sweaty hands have been over them. |

Originally, when the 92's and 95's and probably the 96's were delivered the CTBC lacked the black rubbery stuff thats now in place. Some operators found this incredibly inconvenient as after a short period of time, the CTBC did indeed become slippery. Some ops solved the problem by either wrapping the CTBC in foam or black insulating tape or wearing gloves. Now that most of the time the 92's are in Auto mode, this is unnecessary. Even tho the CTBC's now have the rubbery stuff, some ops STILL use gloves or wrap a cloth around them. Once I did see a District driver using a cloth around the CTBC. I think the whole cab on 92's is covered with sticky tape; not just the CTBC.  |

Err, me thinks thats a push-out job... followed by much leapfrogging... On our semi-old stock here in Stockholm, before the refurbs, the controller handles where mounted with a screw and thread mounting. Thus, it became a rather popular sport to unscrew the handles in the rear cab immediately before being relieved, hide them somewhere in the cab, and give your relief a little treasure hunt when he or she changed ends. |

I've heard rumors that the CTBCs can be ripped out of the armrests if you really do try hard enough - Is that true? ;D |

I even had a train that had the black bit of plastic [so called armrest] taped down; too tempting to look inside, and I could see that theres a sort of pin that goes through the CTBC in the bit that you cant see. This pin, I guess, when the CTBC is wound right up, hits the casting of the CTBC pedestal, so, if you did try hard enough, you *could* in theory, break the pin. I agree that common sense says that you shouldnt attempt this quest. |
