Someone once asked what the deal was with the OHLE mast blocking the link between platform 6 (NR) and 51RD (LU). Are Metrobungle and Notwork Rail still arguing over it?
Also, has any more detail emerged as to what sort of electric detection the shunt signalling for the link will have?

LUL are waiting for Network fail rail to grant a possession. As it doesn't really benefit them, they're obviously not in a rush!

There were some metromess guys working on the new track today - so perhaps things are starting to happen again  |

Ive heard November before they even start marking out the site for the new overhead gantry, so with that in mind is it really worth creating the link because the time they eventually get round to it they might as well just keep sending the refurbs by road, and why does the policeman at the start to platform 5 have to be 10MPH  couldn't they make it 15MPH like most terminal platforms because it seems pointless to me as drivers slow down for it then accelerate afterwards into the rest of the platform. |

There were some metromess guys working on the new track today - so perhaps things are starting to happen again This work was actually in connection with a current possession on 51 road to allow repairs on the depot walkway. In places we have boards over 51 road, while new bits of the path are put in. Just re read TheOneKEA's original post - regarding electric detection; As I understand it, stock moves will be carried out under a full possession. That is all moves within the confines of the depot, along 51 road and onto Network Rail metals. With this in mind, I would imagine that signalling in the conventional sense will not exist - therefore a D stock under it's own power could not be offered a wrong route, as there would be no signal for it. For added safety a fixed trainstop could also be put in to trip a train, should it somehow boldly go into pastures unknown. As far as will it ever be done in time - Bombardier are only on their 5th train (the only one away at the moment), with another 70 to go. We should have 3 trains away at any one time, so the refurb programe is far from running at full pace. Also Bombardier will take over maintenance of the D stock once all trains are refurbed, so they're taking their time getting to know the trains while waiting for the Upminster connection to be completed. TMBA - with very few exceptions, terminal platforms have a speed limit of 10mph. I would agree that where two 'policemen' are present, you can get away with 12mph at the first - but the one for platform 5 at Upminster is technically correct (and is there to protect workers while the connection is installed). Sorry to go on, but I think that covers it all for now. |

The walkway along side 51rd to Upminster Depot was renewed only last year, must be the poor workmanship by Metromess that it needs to be done again The refurbishment of the D stock is running about 1 year behind schedule |

Thanks for all the info but you missed the point unfortunately about the policeman, what I was trying to get across is that the 10 MPH is correct, of course it is but the point is because its 10 MPH and its at the head of the platform and there is no other policeman there Drivers will accelerate into the platform from the policeman, its a natural thing to do, at Richmond or Ealing or any terminus where there is a 15 to start with and a 10 MPH policeman half way down the platform do you see drivers winding up again? thats the point I'm trying to make, unfortunately its a catch 22 situation. if its 15 its good enough but protection doesn't exist, if its 10 MPH its too slow and drivers wind up into the platform but protection is enough.
Its 15 MPH into platform 5 anyway so why not just place the 10 MPH 20 or 30 yards further into the platform it might alleviate the situation and stop drivers winding up.

I see where your coming from on this TMBA (apologies for misunderstanding your point  ), if it was part way along the platform it would still afford the desired protection and allow a realistic approach (Olympia has the same problem). Perhaps it's a set distance thing? |
