Gospel Oak to Barking Line (GOBLIN) electrification

[Roast Veg]

A gratifying site -so obviously not auto-transformer.

Correct me if I'm wrong, but isn't all of the supply for GOBLIN is coming from existing sources rather than new substations?

Upthread a way was a link to a NR update which states:

Electricity will be provided by three new power switching stations along the route and one of these is already in place at Gospel Oak. A second near South Tottenham is almost complete and a third will be installed close to Barking station in the coming months. Each switching station links to two power supplies at Acton and West Ham, so if one supply breaks down engineers can switch to the other, minimising disruption for passengers.

So no new substations as far as I can work out.

Extra power feeds were provided at Acton for Crossrail so probably have the capacity to deal with GOBLIN too.

I see what looks like return conductors in traji00s picture but no traction bonding off the steelwork yet.

Those look like Earth wires not Traction return as there are no signs of the small insulators used on return conductors but solid bolting to the stanchions

Just passed over the GOB on the ECML at Harringay. The Down Line now has a wire run on it passing under the ECML bridge.

I imagine GOBLIN will be a rounding error on the power supply when compared to Crossrail operations....

Exactly - I totally agree

Not quite, once electric-hauled freights with Class 92 start along there.

What 92-hauled freights would those be?? :?

What freight loco traction is likely to begin seeing use on the line when it's electrified?

 

[Freightmaster]

Exactly the same as before the line was electrified, I would expect!

Even if the 92-hauled GB Dagenham car train (which curently runs via the NLL)
was rerouted to use the GOBLIN next year, it runs late at night in both directions,
so shouldn't create an unmanageable power drain.

The line is open today for driver training trips and freight paths only.

Is the electricity on?

Just a little update. Went along Ferry Lane in Walthamstow today which is beside the GOBLIN. Wires now fully installed on both eastbound and westbound tracks. Obviously I am not an electrification engineer but the contact wire, hangers and upper wire are all in place. Not sure how far east they have got - possibly as far as Queens Road but I'd need to go and check. Pleasing to see after such a long wait.

 

[reddragon]

Looks like my dates were close. Work should finish at Queens Road for now, phase 2 in the next possessions.

Had a look at the line from Selborne Road, near Queens Rd stn today. No wires have got that far yet which suggests they've terminated the wiring work near Blackhorse Rd for now. This section is one with tight clearances even with the lowered track. and then we're on to the viaduct section where mast installation has lagged. Not sure if the masts are all now in place on this section as haven't been along it for a while.

 

[332 > 444]

Haven't been further east in a while but is the wires still up Woodgrange Park to where it joins the LTS line? Up the front on an ECS to Letchworth, i see the Harringay Park Jn hasn't been wired as yet either. The viaduct after Queen's Road have registry arms no, and up to about a week and a half ago, they haven't reached Wanstead Park.

 

[450.emu]

I saw the engineering teams this afternoon working on the line between South Tottenham and Blackhorse Road, seemed to be looking at the droppers and contact wire. Looks pretty much done on this section but at Wanstead Park (near Forest Gate) no wires, but masts up.

Second phase of the blockade has now been confirmed by Network Rail - 18/11/17 to 14/1/18. Diesel trains run again from 15th Jan. Work will be concentrated on the eastern end of the line in this second blockade.

https://www.networkrailmediacentre....ack-with-confirmation-of-winter-closure-dates

The line is currently closed with weekday services resuming on Monday 23 October. Weekend closures will continue and the line will fully close again from 6.30pm on Saturday 18 November 2017 until Sunday 14 January 2018 inclusive.

This project is on track for the introduction of new double-length electric trains from spring 2018. The new electric trains will carry twice as many passengers and improve air quality for people living near the railway.

By the end of the current closure 90% of the line between Gospel Oak and South Tottenham will be wired. From Saturday 18 November 2017 until Sunday 14 January 2018 Network Rail’s orange army will shift focus to largely working between South Tottenham and Barking, installing the remaining structures, wires and testing the new infrastructure. The whole line will need to remain closed as we work to towards connecting the new electrical infrastructure into the wider surrounding rail network and switching on the power.

Ahead of this upcoming closure another series of public information sessions will take place at six stations along the Gospel Oak to Barking line from Tuesday 31 October until Thursday 2 November. Staff from Network Rail, Transport for London and Arriva Rail London, the operator of London Overground, will be available to answer questions at the following stations from 4.30pm to 6.30pm:

* Tuesday 31 October, Gospel Oak and Crouch Hill

* Wednesday 1 November, Blackhorse Road and Walthamstow Queen’s Road

* Thursday 2 November, Leytonstone High Road and Barking

Meliha Duymaz, Network Rail’s route managing director for Anglia, said: “I’d like to thank our railway neighbours and passengers for their continued patience while we work round the clock to electrify this popular route.

“The Gospel Oak to Barking line is set to benefit from a transformational, once in a generation upgrade with a new fleet of longer, electric trains so that twice as many people can travel comfortably. Our teams will be on hand at station events to explain the work and answer any questions passengers and neighbours may have.”

Two-car diesel trains will return on Monday 15 January 2018. Testing of the new electrical infrastructure and new trains will take place in-between passenger services and at night with new trains entering passenger service from spring 2018.

Passengers should check before they travel and plan their journey in advance at tfl.gov.uk

I took a ride from Barking to Gospel Oak & back to Blackhorse Road on Oct. 26th.
The OHLE from Gospel Oak to 1/2 way between Blackhorse Rd & Walthamstow Queens Road seems to be almost complete, with a few snagging items needing attention. At South Tottenham the connections between the existing OHLE towards Tottenham South Jct & Seven Sisters aren't complete yet.
The Holloway bank junction is wired but not the bank itself, as the west-bound loop after Upper Holloway. The overbridge at Crouch End is wired, with the contact & catenary wires side-by-side.

From Walthamstow eastwards most of the steel-work structures are in place but not much more.

HTH, David C.

Like Delticdave I took a little spin along the GOBLIN today. Nothing much to add to the detail he has provided but I did take some photos. I believe some forum members have expressed a desire to see some snaps. The link below is to my London Overground Flickr album but the most recent shots are of the current state of electrification at Blackhorse Rd and Upper Holloway. I will add two more shots from Wanstead Park later on but they just show the state of mast installation, not wiring.

Seems about as glacial as all the rest of the current OHLE schemes though at least its not been cancelled midway through. Thats a thought I just had, what have the 172s been doing while the line has been closed all this time? I am presuming just stored at the depot?

To be fair the pace has picked up noticeably in recent weeks. That doesn't excuse the past mess and the fact we're into a second lot of blockades but at least we are heading towards completion all being well.

During the first blockade months ago a number of the 172s had works done to them by Bombardier. That was planned work. I've heard but not seen any photo evidence that some of the 172s did occasionally work in mutiple to cover some extra peak slots on the NLL and also the WLL. Otherwise yes you are correct that they were sat in the depot. They'll soon be having another 8 week break and then they'll be into their last few weeks of service assuming the class 710s are on time and get into service quickly and reliably.

Yes, a little pot of HP sauce told me all meetings cancelled, big commissioning works on OLE planned 8-10th weekend. Fingers crossed eh!

 

[332 > 444]

Wires now up on the line going from Leytonstone Cann Hall area towards Blackhorse Road, probably further but I've not gone that further.
For my info, is that known as the UP Gospel Oak line?

 

[greatkingrat]

The official names are Up Tottenham and Hampstead line (going towards Gospel Oak) and Down Tottenham and Hampstead line (going towards Barking).

Prior to this latest blockade the wires had got as far as Palmerston Road in Walthamstow from Gospel Oak. The wiring train has clearly been busy this week as it's been reported at Leyton Midland Road and has now reached Cann Hall. I assume teams have been along in advance filling in the few gaps there were lacking vertical drops / hangers from the transverse masts. Almost all the side mounted masts had their "hangers" (sorry for non official term) in place.

 

[332 > 444]

Registration arm is the name for them. The part that connects to the contact wire? Also the arms are in place (not in position) on the Harringay Park junction but no catenary wire yet, only the return wires.

 

[Skimpot flyer]

Passing over the GOBLIN on a Great Northern service today, I noticed the connecting line down to Harringay Park Junction has the hangers (registration arms) attached to the masts now, but turned through ninety degrees, so that they are not directly above the track. No catenary wire yet, obviously
