If it's absolutely necessary to have no tripping hazards for a detrainment, would a folding lip of some kind be possible? Or what about a rubber seal on the bottom of the door to fill the gap? That would probably be easier to retrofit without taking a train out of service for a prolonged period. Similar to.... Sorry to stick my awe in, but i noticed the gap the other day and i can help but think, whats would be wrong with a rubber wiper. that would do the same job? Unfortunately I believe that they wear out and are prone to breaking off.    |

I think one factor in the business case is the frequency of nasty fluids getting under the door which must be a lot more than the occasions when passengers have to be detrained through cabs on surface stock.

The lip could be painted orange to make it obvious that it is there. I'm sure I tripped on something similar in the 72 Mk I in Acton at least once.

My suggestion would be to have a thick "comb" of nylon brushes at the bottom of the J Door which would be impenetrable for fluids, act as a sweeper away of nastiness so that the t.op does not step in it left by ill-thinking passengers, and also cut down on draughts without wearing out.

We considered these but ruled them out. I personally thought a brush strip would be a good idea, because as you state, it would also effectively sweep the fluids away from the door when opened. BTUK say that in their experience these brush type strips prove ineffective and a maintenance liability. Oh well.  |

Can I just say, I thought that post was well put together and extremely funny, maybe it's just my weird sense of humour! ;D ;D |

On buses my experience of brush strips is they can be penetrated by liquids, they also loose bits of the brush that comes adrift from it's grip and they never get replaced no matter how often the driver books it off.
As for the strip, i fail to see why it should be a trip hazard if, in fact this has a chamfered edge, that is to say it is a strip of so called "half round" aluminum. It has no specific vertical edge to trip upon, it's "half round" shape would merely push up and over any foot coming into contact, but would prevent liquid ingress.
Also at common law a trip hazard generally has to be a difference of level of 1/2 inch or more, unless there is some specific legislation in this regard ??

Just stating the obvious, but isn't area between the communicating doors a trip hazard and being a complete pedant aren't the detrainment steps??!! ;D |

This is exactly what BTUK stated when we made the suggestion of a brush strip. It's good to know that there is some circumstantial evidence to back that up. Thanks.

This is exactly where we are now coming from. I'll keep you posted on progress. |

How about something akin to the cable ramps you see in offices? You know, if something has to be plugged in and a lead trailed, a rubber ramp is put up. It could be steep enough to stop fluids yet not too steep to be easy to trip over.

Thats a good idea. I suspect the proposed lip design will look something like that. Thanks.  |

I passed driving motor car 7035 this afternoon in Derby. It is sitting outside all by itself, uncoupled, unrefurbished and looking very sorry for itself!

Just to add to DStock7080's list, the other half of 7035 is 7030. 7092, half of train 45 was released to the District fleet on 02/05.
The following are the next planned units
49 7036 + 7091
50 7526 + 7525
51 7010 + 7039

The brushes are used on the doors bottoms, am I correct? Such brushes are used to try to stop cold air leaking out on the Guangzhou Metro Line 1, assuming i remembered correctly. |

The following are the next planned units 49 7036 + 7091 50 7526 + 7525 51 7010 + 7039 So the potential for another 'double bubble' running around (train 50) then? |

Highly unlikely - if you notice in the past lists, all double-enders have gone away as a pair. However, they don't seem to run around together either before going away or after they return now. |

I hadn't really taken much notice of the double enders refurbishment pattern (not being a train spotter   ;D ;D) - but I take your point  As it happens, I had 7524 the other day - it was married with 7093, which proves your point nicely! |

I had the meeting regarding 17008, in fact it took place on the unit itself! Metronet want to do a minimal amount of work but LU want a more extensive amount of work to be carried out. As a result I have another meeting to decide on a course of action in the next couple of weeks. Again I will update you further at that point, I don't want to say too much at this point as I do not want to tip LU's hand on this one (MRSSL staff read this forum!).

It'd be nice to have 17008 left as an oddity for the trainspotters, but I can see why LU would want it to be up to spec with the other units, for the whole uniformity thing.

I guess the opportunity to take any photos of unit 7008 working with unrefurbished stock is now somewhat limited... Catch it while you can would be my advice... assuming its still in service and hasn't already been sidelined |

Not really limited - no more than it ever has been anyway Since it hasn't been refurbished, it can only ever run with another unrefurbished unit Thus, the chances of seeing it are the same as it always has been ;D |

Not a problem Unfortunately I had the misfortune to have to work this unit on Sunday morning, for four hours Whilst it may be a novelty for most, for the drivers it is a complete PITA as the cab is white, so makes it impossible to drive in the tunnel sections with the cab light on, and not that good with the light off |

Bring a can of emulsion & brushes with you to work would be my suggestion.... ;D ;D ;D While CitySig keeps you waiting at his signals you can redecorate using your best Rolf Harris impression |
