Would that Belsize Park Overground station be the only underground station with regular freight trains passing through?  |

Seven Sisters chord being rewired today. Presumably this ties in with the planned energisation of the east end of the wired GOBLIN from tomorrow. |

Another NR tweet - this time about testing the live overhead on the GOBLIN, more specifically at S Tottenham if you look at the tweets linked to that one. |

Confirmation that the Crouch Hill bridge raising works start in the New Year. |

Interesting - works appear to have started already, temp traffic lights are already in position.
The road closure will be interesting especially with the W7 bus being so frequent and well used - any tiny delay results in buses being missed owing to overcrowding, and the diversion route I imagine they will adopt (via Hornsey Rise) is slower.

Courtesy of another forum I've found Network Rail's most recent "Enhancements Delivery Plan". cdn.networkrail.co.uk/wp-content/uploads/2017/12/Enhancements-Delivery-Plan.pdfGOBLIN electrification is on page 149. Looks like the work is very nearly complete. Key date listed are :- 2 Jan 2018 - Entry into service for testing and driver training 5 Mar 2018 - Authorisation for entry into passenger service (I assume this a regulatory sign off) 2 April 2018 - First timetabled use of the new infrastructure (I take this to mean a class 710 in passenger service) |

It is now expected that the first two units that will carry out route proving will be available on the 6th March. |

Possibly up to 2 months late given the first one should really have turned up by now (if I recall the contract delivery schedule correctly). |

When are the 710s due to be delivered?

From Barking Flyover to the Platform 1 becomes electrified on Boxing Day

From Barking Flyover to the Platform 1 becomes electrified on Boxing Day Really? I thought it was energised *ages* ago given it is surrounded by other live wired infrastructure. I clearly misunderstood an old tweet from NR GOBE team. |

When are the 710s due to be delivered? One or two should have been here by now *if* the production schedule had been adhered to. I wonder if they are late because they have software and other systems in common with the 345s which are struggling to get into service / achieve reliaiblity / keep having software updates. No point sending 710s to TfL / Arriva if they haven't got the latest (more reliable?) software in them. The implication from Dazz's earlier post is that the 710s may be a couple of months late. |

The reason for much of the delay to the programme is now centred around the TCMS software. For the 710's it is a bespoke programme currently being developed by two companies in Sweden and India and it seems that collaboration is not working to the original timescales. |

Possibly up to 2 months late given the first one should really have turned up by now (if I recall the contract delivery schedule correctly). The contract 'allows' for delivery of up to three units during December, but the actual deadline date for first deliveries is in mid-late February 2018. |

Is any test running planned on the GOBLIN before it reopens next week? ISTR that a few refamiliarisation runs were done prior to previous blockades finishing. Note I am not talking about EMUs running, just the class 172s.

They have to wait for ORR to sign off the overhead so by that time (March?), there will be at least 3 possibly even 4 class 710s available. |

There is a converted carriage known as MENTOR:  I believe there is also a similar MK3 based vehicle which can be added to the HST based measurement train. |

I was thinking that but then wondered if it was wise to use something relatively untested itself on new infrastructure. Edit: The wizard seems to have found what it is (above).  |

If that is the case, then processes are already in action as a train with electrical equipment has been given a test path to run in the early hours of Friday 12th Jan from Gospel Oak to Seven Sisters via South Tottenham and Tottenham West Junction and back to Gospel Oak. It is an unclassified slot (FRGT) , that's usually a test train with electrified equipment which as rincew1nd says is the MENTOR. |

I might be wrong but I thought they also "stress tested" the electrical infrastructure by running a freight loco or even a Pendolino which will draw a large current. I've seen that suggested on another forum. I assume something similar would have to be done, no doubt in eng hours, as part of achieving sign off of the GOBLIN wiring / sub stations / power feed. Happy to be corrected / educated. |

www.traintesting.com/Loadbank.htm says that Class 90s were used prior to that (including to Heathrow Terminal 4). The same website indicates that the 86/9s are currently in store, so what is used these days I don't know. One is being raided for parts having been rescued from Rotherham, the other was stored in Rotherham for a longer period of time, with inevitable consequences!The Liverpool - Manchester scheme used 390s, but as noted in the link from traintesting that you've provided, it's mainly to do with return currents and the effects of them on the infrastructure, or more pertinently with modern AC motored traction, if the return currents will interfere with any of the trackside electronics. That's why the 390s saw use on the Liverpool - Manchester route, because they were/are occasionally diverting along that route to get to Liverpool if engineering works are preventing the usual route from being taken. From what I understand, there is no need to Stress Test the supply Similarly with Great Western, no special load bank vehicles were used, just the trains that'll be operating along it, namely some 387s and some 800s, which did highlight some issues with the 800s and the signalling systems, but that's all been resolved, for now. I'd expect that the GOBLIN will simply just be tested by MENTOR (to check that the overhead is in the right place, the right tension, etc) and then some 710s |
