Crossrail 2 map: Tottenham & Seven Sisters

Crossrail 2: trains exit tunnel at Markfield Park

The case for the Crossrail 2 north-south rail link gets stronger every day. This proposed project is vital to provide improved public transport in London, and the plans feature welcome improved links for Tottenham Hale and Seven Sisters including South Tottenham station. But there remain crucial questions on its impact on local residents, both during and after construction.

The latest plans were revealed this week and provide more detail in the form of a Crossrail 2 interactive consultation map.

They make the option of a tunnel portal at Copper Mill Junction on Walthamstow Marshes less likely. This had caused much disquiet at the impact on this marvellous open space and its wildlife. However the proposed tunnel still emerges above ground to the SOUTH of Tottenham Hale, in a strip of land running northwards from behind the Markfield Beam Engine to Tottenham Hale station itself.

Crossrail 2 and Markfield Park

It is unclear how great an impact this would have on the museum and Markfield Park itself – both during construction or after it.

Construction would last several years, with the work site hugging the top of Markfield Park. This clearly raises potential questions about both noise and air pollution, and what would be done to ameliorate effects on users of the park and its popular café.

Once built, the proposed train service includes a Crossrail 2 train every 4 minutes (or 15 trains an hour). These trains are big at over 200m long (two full-sized football pitches) and travel at up to 140 km/h (90 mph). If the tunnel does emerge here important questions are raised on reducing the impact of these trains hurtling by on both Markfield Park and residents of Jarrow Road and nearby.

One issue that may continue to be raised by local residents and groups is: what consideration has been given to the tunnel emerging to the north of Tottenham Hale? This is an area which is more industrial in nature and so may be more suited. Also a continuation of the tunnel further north would go some way to solving the problem with level crossings on the line towards Broxbourne.

Meanwhile to the south, there is a proposal to build a two storey ventilation shaft near to Stoke Newington station. Construction would take around six years from start to finish.This would be a major work in itself, and the worksite appears to involve the demolition of the large Morrisons.

Crossrail 2 consultation results in all options open

The results of the Crossrail 2 consultation have been published with opinion split on its Hackney route and concern over any possible tunnel entrance on Walthamstow Marshes being raised by several respondents. The option of the tunnels emerging north of Tottenham Hale was also raised by some.

As a reminder, the consultation states:
[The plans involve a] tunnel portal to the south of Tottenham Hale, although the exact location has yet to be determined. Further engineering feasibility work is being carried out to review options for the tunnel portal and the impact this would have on the area required.

A 2013 engineering feasibility study had placed this portal at Copper Mill Junction on Walthamstow Marshes. A detailed analysis of this and other possibilities is in our previous post, Crossrail 2 emerges on our doorsteps?

For now, it seems no option has been ruled out – or in – and local residents and users of Walthamstow Marshes, Markfield Park and the River Lea must wait and see.

In their response, LB Haringey notes “the potential for impact on regeneration around Tottenham Hale station through the use of land for a tunnel portal/worksite. Ensuring appropriate development platforms are provided following completion of the railway to maximise the benefits of the new route, and minimise the areas of working required to facilitate delivery must be the objective of all parties.”

Love the Lea festival

A free festival celebrating the Lea takes place next Sunday (17 August). The all-day event is just down the river, in the Walthamstow Marshes picnic area (opposite Springfield Park), and features live music, boat trips, sound walks and more.

The event also features #urbanflowevent (rivercities): a cross-arts, public participation project that forms part of series of works linking Sweden, Canada and our own Lea Valley. People are invited to come to a practice session and dress rehearsal on Saturday 16 August 4-6 p.m. (same place). Children aged 9-13 are also required to perform a dance in the festival and a dance workshop will take place on Friday 15 August at the Sea Cadets Building, Spring Hill, E5. Additionally people are invited to contribute river/marshes photography to Sirenscrossing’s new blog site and/or facebook page. Organisers Carolyn Deby and photographer AnnaCarin Isaksson are also inviting people to attend a creative workshop on Thursday 14 August either 10 a.m. to 12 noon or in the evening 6-8 (as agreed with participants). Find out more on their tumbler http://Sirenscrossing-rivercities.tumblr.com/ or contact Carolyn Deby on rivercities@sirenscrossing.com

Tour de France to whizz past

The Tour de France is coming to London next Monday (7 July) with the route including part of the Lea Bridge Road, a modest walk from South Tottenham.

The world’s most famous cycle race is primarily held in France, but this year includes some UK stages. Monday’s part of the race sees competitors cycling from Cambridge through Essex and then on to north, east and central London before finishing on The Mall.

This excellent interactive map of the whole day’s route also shows crucial details such as elevations. Last year’s winner Chris Froome is part of a multinational squad in “Team Sky”, although Bradley Wiggins did not make the cut.

Tour de France Lee Valley mapThe nearest point of the Tour de France to South Tottenham is a roughly 40 minute stroll down the River Lee and across Walthamstow Marshes.

The racers will come from the east, along Lea Bridge Road, before turning left down Orient Way to head to the Olympic Park. Many of the side roads along the route will be closed or restricted until the race has passed.

Crossrail 2 emerges on our doorsteps?

Crossrail 2 is a great idea – and a vital project to provide improved public transport in London. But the latest route announced this week still leaves local residents unclear about the threat to local marsh and parkland, and with crucial questions on its impact.

Crossrail-2-Route-Map-sidebarIf the line gets built, fast, frequent trains would reduce overcrowding and encourage people to leave their cars at home. Locally journeys from Seven Sisters to Euston, St Pancras or Tottenham Court Road would take only 15 minutes with trains running through to Victoria, Clapham Junction, Wimbledon and beyond.

London Mayor Boris Johnson has been pushing for the route to go ahead and earlier this week he announced a revised route that could see the line open by 2029.

Impact on South Tottenham?

Much of Crossrail 2 would be built underground. However one branch of the line would emerge from its tunnel somewhere “to the south of Tottenham Hale”. At the moment the exact location is undetermined. This week’s consultation says:

“This change would result in a new location for the tunnel portal to the south of Tottenham Hale, although the exact location has yet to be determined. Further engineering feasibility work is being carried out to review options for the tunnel portal and the impact this would have on the area required. Once the location has been agreed, further consultation with stakeholders and the public will be undertaken.”

crossrail2-tottenhamHale-satellite

The satellite view reveals there is not a lot of space for this “tunnel portal”. Is the small area north east of Markfield Beam Engine Museum a possibility? And what impact would this have on the museum, Pistachios in the Park and the park itself? Or will the tunnel emerge further south, on the edge of Walthamstow Marshes near Coppermill Stream? Remember this is a “high frequency, high capacity rail line”.

Some questions

What is the reasoning behind the line coming above ground south of Tottenham Hale? This area is predominantly residential interspersed with rare and valued open space.

Wouldn’t the tunnel portal be better situated in the predominantly industrial zone just to the north of Tottenham Hale?

More details on the overall plans can be read on the Crossrail 2 website. TfL is running a consultation until 25 July showing full details of the local route options. Question 7 of the accompanying online survey is a good place to raise concerns as it asks for “Comments about the route north of Angel”.

 

[UPDATE 14/7] Tunnel entrance at Coppermill Junction?

Research by southtottenham.org has revealed some interesting detail to these proposals. The document “Crossrail 2: Summary of Option Development” written in May 2013, specifies:

“… [Crossrail tracks] then surface to the south of Tottenham Hale close to Coppermill Junction.”

Coppermill Junction on Walthamstow Marsh

This is tantalising glimpse of what the plans may involve, in a document apparently written by infrastructure firm AECOM for TfL. The route south of Tottenham is still very much up for grabs in the consultation, but this suggests the plan is for a tunnel entrance on the edge of Walthamstow Marshes.

View over Walthamstow Marshes – under threat?

The document continues:

“The branch could then join the WAML at a grade separated junction.”

So the emerging tracks would join the existing main line (WAML) in a grade separated or flying junction, with tracks criss-crossing each other via an underpass or bridge. Then…

“The WAML may have been partially 4 tracked before Crossrail 2 is completed and the Crossrail 2 lines on leaving the portals would join the slow (suburban) lines”

This implies the track will be doubled from the existing two tracks running alongside Walthamstow Marsh, between the Warwick Reservoirs, past the corner of Markfield Park, over the River Lea, and up past Yarmouth Crescent and Jarrow Road into Tottenham Hale. Interestingly such tracks used to exist, and the remains of an old bridge can be seen over the Lea adjacent to the existing rail bridge.

Walthamstow Marshes

Bear in mind Walthamstow Marshes are a Site of Special Scientific Interest and “one of the last expanses of semi-natural marshland left in London. Extending to 88 acres, they are unique in the Lower Lea Valley” (read more via the view from the bridge)

This is an inheritance worth protecting.

Would the users of Walthamstow Marshes and Markfield Park – together with local residents – not be served by the tracks emerging above ground somewhere beyond Tottenham Hale? Perhaps some of the wasteland between the Victoria Line sidings and Northumberland Park station could be used? This would have far less impact on our green, open spaces.

Another more community-friendly point to bring the tracks above ground might be just to the south of Angel Road station, by the derelict gas cylinders next to the North Circular. This would also by-pass the Northumberland Park level crossing which saw a person hit only last year – and is already rated with the second highest “Collective Risk Rating” of an incident involving a person or vehicle. No doubt this option would be more expensive – requiring subterranean platforms at Tottenham Hale and an extra 4km of tunnel – but has it even been considered?

Why is the current consultation documentation stopping short of spelling out these consequences? Is the plan really to “plonk” the tunnel exit in an environmentally and residentially sensitive area rather than industrial zoned land a little further north?

[UPDATE 18/7]“A highly sensitive location”

I have just received the Lee Valley Regional Park Authority response to the Crossrail 2 Coppermill Junction plans:

The ‘Regional’ option implies works to the Coppermill junction which lies on the northern edge of Walthamstow Marshes which is part of a Site of Special Scientific Interest. This is a highly sensitive location and construction should avoid this area. The Authority could not support any scheme which would result in an incursion into this area.

So, is this plan off the table? TfL haven’t told us. As the millfields blog points out today:
“TfL say they will consult again after they have decided how the railway will travel through the Marshes towards Tottenham Hale. This is the wrong way round. Local people deserve to be consulted on the range of options and to fully understand and comment on the implications before a decision is made.”

 
The TfL consultation only runs until 25 July – you can read more on their website and respond online here, where question 7 asks for “Comments about the route north of Angel”. Time to get writing…
