That doesn’t sound right considering that Bombardier built the trains.

A snippet of dynamic testing in this video showing wrong road running between Farringdon, Fisher Street Emergency Crossover and Tottenham Court Road.

Note overhead line pickup.
Must be intended for through running on the Great Northern & City!

Note overhead line pickup. Must be intended for through running on the Great Northern & City! It's all overhead. The initial testing was all done on one track so bi-directional running was needed. The illuminated panels above the doors are capable of showing trains in the wrong direction. |

Can Fisher St crossover hold a train? Is there anywhere to hide a defective train in the tunnel section?

Can Fisher St crossover hold a train? Is there anywhere to hide a defective train in the tunnel section? I’d assume not based on the fact that there are no TVM markers in the section of track between the two sets of points for Fisher St and Whitechapel only before and after. The sidings west of Paddington would be the only place on the combined core section to keep a train out of the way but of course that’s in the open. |

There are sidings at Abbey Wood, but if there is a problem on that branch, they would have to send trains up to Ilford depot or Chadwell Heath reversing siding.

Makes sure. Another month or so isn't going to make a huge bit of difference at this stage...

Custom House is the first central section station to be completed and handed over to TfL:
To be honest that surprised me as although it's a surface station I actually thought Canary Wharf was pretty much done.

I think we heard that Canary Wharf was finished so early, it doesn't fully meet current standards and needs some modifications!

Was listening in to the TfL Board Meeting today whilst doing some baking, some extra details came out that aren't in the agenda papers.
In addition to Custom House station being handed over to Rail for London, six shafts and portals have followed suit.
All core stations bar Bond Street are now complete to an acceptable standard to commence trial running. Bond Street is expected to be ready in 4-5 weeks.
Major questions remain over the push to get trial running underway before the year is out. At the time the safe stop was implemented and access was removed, it was estimated that only seven further tests were required to get the signalling software to an acceptable level of functionality for trial running.
Dynamic testing resumed this weekend past with a regression test, signalling software verification is expected to be completed in the next 4-6 weeks. This provides an assurance platform for certified use of trains in the core. A further software drop is planned for this Autumn aimed at addressing reliability and functionality.
Another risk quoted by Mark Wild was scenario testing, ventilation noise, smoke suppression and track dampening effectiveness etc. This form of testing was at around 40% completion at the time of the safe stop. To date this is now at 60%. A blockade of the core between this August and September is planned in order to recoup some of the lost time in this regard.
Plans are afoot for the early handover of Crossrail assets shared with London Underground for example the ticket hall at Moorgate, dates are TBC whilst the impact of how socially distant working will affect the outstanding works to be completed at the four stations concerned.
Following the lengthenings out on TfL Rail West, commencement of 345 airport services was stated as happening, "in the next short number of weeks when the appropriate training is completed and the various verification is received".

All very well to hand over to Tfl, but the way things are they probably can't afford it.

Handover of Moorgate ticket hall would allow a gate line to be re-instated and the temporary entrance/exit removed.
It could allow step free access to the Circle/H&C/Met platforms if the lifts are commissioned.
Station handovers also mean that the systems and equipment can be tested.

I don't think TfL would have the legal option of saying "Sorry guv, can't afford it now, you can sell it to someone else!". TfL will want to get the core running as soon as reasonably possible, because the fares and other revenue will be critical to offset the ongoing operational costs that can't be avoided (station staff, drivers, train leasing etc). |

Network Rail news June 17, 2020 "TfL works to lengthen platforms 16 and 17 at Liverpool Street will begin over the Christmas period to make more platforms available for the new, longer Elizabeth line trains; Network Rail works for the Crossrail programme will continue with station upgrades taking place at Ilford and Romford this autumn." Does Elizabeth line refer to the service and Crossrail refer to the infrastructure? See: www.networkrail.co.uk/news/major-improvement-work-to-be-rolled-out-across-anglias-rail-network/ |

jimbo , Effectively yes, Crossrail is the construction arm of the project which will morph into the Elizabeth line which is the service being offered over said infrastructure. That hasn't stopped the terms being butchered at every level thanks to the changes we've seen over the past five years!

They're using conductor rail instead of standard wires, BTW. Not quite true - the actual conductor is still copper wire as per 'traditional' overhead line systems - its smoothness and electrical properties not having yet been bettered. The main change is rather than the conductor wire be suspended from a flexible Catenary system, it is clipped to a solid bar structure making the structure robust yet simple to install.
This contrasts with true 'conductor rail' systems where the pick up on the train actually rubs along the rail surface.
Note as per traditional overhead systems, the bar (and thus the copper contact wire) wiggles from side to side as it goes thus avoiding wearing a grove in the pantograph head.

See: www.networkrail.co.uk/news/major-improvement-work-to-be-rolled-out-across-anglias-rail-network/Interesting - but if i recall correctly the works at Liverpool Street will reduce the number of platforms available so either they are banking on train services still being Covid reduced in 6 months time or else there will have to be a thinning out of TfL Rail services to Shenfield to suit the reduced number of platforms at Liverpool Street High Level.
As has been noted before NR are not in a position to simply wait till Crossrail is ready as the Liverpool Street works are tied in with lots of other things (in particular demands on resources) happening around the rest of the country.

There would be 15 other platforms available, five in the relevant half of the station.

Liverpool Street station is used by more than TfL rail!
It has been made clear in the past that the remodelling work would permanently reduce the capacity for TfL rail services and thus would be done after crossrail was open when some services could be diverted away.
If crossrail won't be opening till the middle of next year, yet capacity at Liverpool street is going to be reduced then something has got to give and cancelling GA services to make room isn't one of them*.
Using 'other platforms' is NOT an option (or otherwise it would already be happening)
The only logical deduction is that TfL rail services will have to become less frequent from this winter till crossrail opens - but will TfL have the guts to admit it (and all the bad PR that goes with it)?
* The national rail network is not TfLs plaything like the tube or DLR. It cannot go round demanding it gets priority or things are done when it suits them however much it wants to.
