When 67TS went on other lines they were double manned as they didn’t have a deadman’s valve.

Obviously the tamping machine can't fit inside the tunnel so therefore the TSRs west of Leytonstone will remain in place until a solution is found. More importantly, a tamping machine is no use when the sleepers are set in concrete, which is the case for a lot of the track west of Leytonstone. When 67TS went on other lines they were double manned as they didn’t have a deadman’s valve. Did they not? I remember they had the vigilance button which I always assumed connected to a deadman valve when in Coded or Slow Manual modes. |

Vigilance button was cut out when in tripcock mode,was a tripcock/vigilance switch in offside equipment cabinet.Train would’ve been restricted to 10mph with vigilance cut in.

Don't want to get anyone's hopes up but some TSRs west of Leytonstone could be lifted soon

oh good! Thanks for the info
its crazy how trains accelerate just as they enter a station - when they should be slowing down!

72 stock with shoes removed will be guided by engineering battery locos for power at either end. These locos are Central Line signalling compliant. It will probably operate in Eng Hours anyway, but that's the way they can round the compliance issues.

It will need to work in Engineering Hours as I expect a 7 car 1972 stock train top and tailed by battery locos will likely be over length. |

Running the 72TS has been extensively explored but cannot be made to work.
The Tamper (now with relevant approvals) will be working all areas between North Acton and Leytonstone within a 2 week programme that commenced last night aiming to lift all remaining TSRs.
Probably a need to run the TRV as well, so the data its able to exctract (gauging) can be combined with the Tamper's measuring data (cant) to create the full dataset required to achieve ultimate removal of the TSRs.

Went on the Central Line yesterday. The TSRs I experienced were:
Leyton to Stratford Westbound.
Between Stratford and Mile End both directions.
Between Mile End and Bethnal Green both directions.

All of these are in the current programme of works and all going well will have been fully recorded by 18/04. Whether TSRs can be lifted immediately will depend on the resulting data. |

I believe the current TSRs are
Loughton pointwork both roads
Woodford pointwork both roads
Newbury Park area O/R
Leytonstone - Leyton W/B
Leyton - Stratford W/B
Stratford - Mile End both roads
Bethnal Green - Mile End E/B
Queensway - Lancaster Gate E/B
Shepherd's Bush - White City W/B
North Acton - East Acton E/B
I believe there's a few more in the western end of the line but I don't have the current list to hand. All TSRs are TSR3 except for Newbury Park O/R and Shepherd's Bush to White City W/B

Yes - The mods will be able to split this into most likely the general discussion/signalling and track section as it concerns multiple lines. Although I'm the OP I don't have the power to move this into another section. I've modified the thread title.

Not without stripping off all the protruding tamping equipment and hydraulics to achieve gauge. In its current state it can do nothing but measuring runs and will need reassembly for any future tamping activities. |

TSRs implemented on Northern and Jubilee imminently More than what's already in place? The Northern has had some for a few weeks already The ones I've noticed are Waterloo to Kennington in both directions Tooting Broadway to Morden southbound Morden to Tooting Bec northbound Currently a max speed of 25mph on these sections at the moment |

Apologies I should have specified. I meant to say that there are already TSRs on the Northern, with the Jubilee following shortly

Mod comment (Dstock7080) done for you Interesting call this one (akin to who will be taking the Bill for LCH/excess journey time). Defo not Signalling problem - they just implement the TSRs requested by Track. Track will undoubtedly say not their problem because the track is probably OK - just it can't be verified via a service provided by others. So it comes down to the Track Recording Vehicle being the route cause - A fleet Asset? But if its down to a lack of spare parts could Stores & Logistics be the route cause ? The good news seems to be that they have narrowed down the problem to one of the track features measured (Cant) - Now hunting for the fix /spare part/ or redesign. |

A piece of work commencing Tues 16th aiming to start clearing the NL TSRs. This should be completed early May.

Good to know work is finally being done to resolve the TSRs. Although it shouldn't have got to this point.

Interesting comments re: which 'cost centre' should bear the burden of the financial implications of the problems being discussed in this thread. I have a question which might be better if split off to a new thread. Was it always like this? ie: have there always been all these (competing?) cost centres - even in the days before the formation of the LPTB? or were the financial implications of issues that affect the service and cause increased (and / or unexpected) operating costs managed differently? |

Yes, but they weren't known as Cost Centres as such. There was always an attribution process for delays.

I think the situation started changing some 20 or 30 yrs ago with the pressure for TFL to be more "Businesslike " with many emotive steps such as outsourcing of buses, PFI/PPP, Outsourcing of many & various works & services, Senior Manager Performance related pay/bonuses etc etc But this is liable to get political very quickly - so lets not go there |

Remember the old days LT had it’s own food production centre at Croydon,they even employed their own rat catcher.Don’t mean Croydon had it’s own rat catcher,guy used to go round system when vermin reported.

TRV was seen on the Central line either Fri or Sat so fingers crossed...

Tamper measuring runs (CEN) are completed and Tamper has been rebuilt to Tamp again, so there's 2 more actual Tamping shifts to complete the programme.
Then the data is combined with the TRV run data for analysis, followed by removal of the TSRs, so still a little bit more waiting, but getting very close now.
Northern Line work is delayed following an operational issue elsewhere on the network that reduced the working window and prevented full scope being achieved, so now expected to take until end of May, but hopefully some TSRs associated with the scope that was achieved, plus scope planned to be achieved next week are to be lifted sooner, if not already.

Interesting news about the Northern line...
Do we have an estimate on when the TSRs will be removed on the Central Line ? Within the next week or so ?
