One of the more complex stations being built by Crossrail is at Whitechapel where they not only had to build a new station above existing running railways but also tunnel underneath them as well.

Whitechapel station is of course, also the answer to the famous pub-quiz question, of which station has the Underground pass over the Overground. The Overground runs north-south in a deep cutting, while the Underground runs above in a shallow cutting in an East-West orientation.

Thanks to the area’s heritage of different lines, lots of lost freight sidings and rebuilds, we’re left with a lot of Victorian engineering, in a very tight space squashed in behind shops and homes, and in a very busy area. For any construction site that would be a difficult site to build on, but having a live railway in the middle of it also massively complicated things.

The project can almost be seen as two separate building sites – the tunnels deep underground, and the huge redevelopment above ground to tie three lines into one station.

Having just a few hours each night to do works over the railway lines was a serious, but known impediment. Less helpful, they were only granted one significant blockade of the line, when the Overground tunnels were closed for 9-days in August 2016.

Very unhelpful though was the totally unexpected arrival of the night tube on the London Overground wiped out two nights a week of work time

Maybe unsurprisingly, this particular Crossrail station is now over budget and late. Although the specifics of the delays are still being reported on, initial reports across the entire Crossrail project have generally laid the blame at the lack of project management downwards by senior Crossrail staff, and the lack of reporting upwards of problems by contractors.

A new team are in charge at Crossrail, and one of the things they have now are weekly briefings. For example, the Whitechapel staff hold a meeting on Monday to discuss issues, then that’s fed up to Crossrail on Tuesday, and to the boss, Mark Wild on Thursday — with the intention that Crossrail can look across its suppliers and contractors for a solution that might not have been available at the contractor concerned.

There’s also a level of awareness now that maybe the early contractors were treating the project as a construction site in a difficult location, and didn’t take into account the relationship building, the complexities, and bureaucracy that comes from building next to four live railway lines.

A lot of last-minute hold-ups due to the necessary permissions for works over the railway lines arriving very late in the day, which might have been less of a problem had they spent more time liaising with the railway side of the building site. That’s in the past – new reporting methods and project management is in place to get the site finished, and to support the testing of the Elizabeth line trains which now pass through the station platforms.

The design of the new station is complicated at first glance, but actually fairly simple when looked at carefully.

The Underground section used to be two separate platforms, with four railway tracks, but is now one very wide platform with tracks on either side. The exit used to be via some narrow stairs up to a narrow corridor to the ticket hall. That concept will remain but now going up a very wide set of steps (and lifts) to a new much larger corridor.

Where the old narrow corridor skirted around the Overground tracks below, the new corridor sits right on top of the Overground and is, in fact, the dominant feature of the new station design.

A huge curving roof and corridor will run above the full length of the Overground platforms, and at the northern end, will be the new escalators down to the Elizabeth line. This image shows the site in profile, with the London Overground tracks running beneath the new curving corridor. The Underground tracks are at right angles to this image, under the apex of the curved roof.

To build this has not been easy

For the tunnels underground, it was almost a routine task. A shaft dug down in the former Sainsbury’s car park allowed access deep underground to start digging out the station tunnels.

Two more shafts were dug at the far ends of the Crossrail platforms, one for ventilation and emergency services, and one for the escalator box to be used by passengers.

The escalator box was a delicate task though, as it sits right next to the Overground tracks, and they needed to ensure that as they dug down, that the Overground tracks didn’t end up offering an unexpected diversion down into the Crossrail tunnels.

A three escalator barrel has now been fitted out, with a very dramatic profile for people heading downstairs. At the moment it’s quite dark but does have a glass roof which will be revealed later.

Down in the platforms, they have the large curved concrete walls we’ve seen elsewhere on the project.

Floor to ceiling glass screens with digital displays for arriving trains, provide protection from the wind as trains approach, but more importantly, as these are mainline trains powered by overhead cables — they need a barrier to stop accidents happening. The upper area also houses the ventilation, and in case of fire, the smoke extraction fans.

A design that looks good has been born out of safety.

Along the length of the platforms are black boxes — and their locations reveal something interesting about the length of Crossrail platforms.

They’re a bit too long for fire hoses.

So the black boxes that house local electrics and supplies, also house a fire hydrant that the firemen can plug into, should the worst ever happen, and they are specifically located at the distance that fire hoses can reach.

This side passage used to be at the bottom of that original huge shaft dug down to start constructing the platform tunnels. It’s been filled in since then as it’s not needed for the station operations.

It’s above ground where the most work needs to be completed before the station can be handed over.

The original ticket hall has had all its internal walls removed to create the much larger space needed, and that will lead up to the new corridor and the ticket barriers.

The amount of scaffolding though is slightly misleading. That side is next to the running railway, and they can only use mobile cherry pickers to get up to the roof next to the railway at night — but scaffolding allows work during the daytime. If the railway wasn’t there, they wouldn’t have needed all that scaffolding.

The physical structure is largely complete, with fresh tiles and ticket barrier machines covered up in wooden cladding — the works are fitting out the electrics and system equipment.

The whole structure sits on top of the Overground tracks, and during the 2016 blockade, they filled the Overground tracks with massive blocks of polystyrene to protect the track as they drilled down for piles and build the new concourse above.

At the moment the Overground platforms are very dark, but when completed, light will flood down from above when all the covers are lifted from windows running the full length of the corridor.

Also running the length of the corridor will be a public pathway linking north and south so people can avoid a detour around the side streets.

There are a number of key deadlines coming up to prepare the station for the public to use.

By the end of October they need to have the station about to allow modest evacuations from the tunnels and the fire bridge down, as that’s required for the Elizabeth line testing.

Later this year, full-scale testing of the railway should be able to start, with potential for hundreds of people to be test-evacuated from the station. Then follows several months of familiarisation for London Underground staff, and it’s likely that the public will be able to start using the new station from next June.

The Elizabeth line will arrive somewhat later, but Whitechapel Station will be open for business.


Thanks to Crossrail and the staff at Whitechapel station for the site access.

This website has been running now for just over a decade, and while advertising revenue contributes to funding the website, but doesn't cover the costs. That is why I have set up a facility with DonorBox where you can contribute to the costs of the website and time invested in writing and research for the news articles.

It's very similar to the way The Guardian and many smaller websites are now seeking to generate an income in the face of rising costs and declining advertising.

Whether its a one-off donation or a regular giver, every additional support goes a long way to covering the running costs of this website, and keeping you regularly topped up doses of Londony news and facts.

    Project Management appears to have gone backwards since I was writing Artemis in the mid-1970s.

    The reporting structures used by companies like Bechtel, BP and Shell in the North Sea were much better. In those days, BP, Shell and other companies insisted that all companies used the same software. As it was Artemis, I didn’t complain.

    If it all went pear-shaped, this enabled the companies to send in their experts to find all the dirt under the carpet.

    Did Crossrail insist on a common Project Management software system?

    I think not and this has led to a lot of problems!

    • Rog Laker says:

      The unasked, never mind unanswered, question remains: where was the new TfL Board, under its new Chair, since May 2016? That is about the same time before Crossrail’s problems were publicised as the revised opening ‘window’ is after it. That is no mere coincidence.

    • Alistair Twiname says:

      You say that you developed Artemis every time crossrail is mentioned. Crossrail seems to have used a custom built management (or at least compliance/approvals system) mentioned here

      I don’t think working in the north sea is exactly comparable, much of the work needed to be done for crossrail was not under its direct control (eg road closures, work on national rail lines, national grid works, local councils etc etc etc) these are not subbies who can be told what to do and how to operate.

    • Paul says:

      @Rog Laker
      I see you’re alluding to a Mayoral election that took place in May 2016.

      I’m not sure it’s justified to try to politicise the Crossrail delays in this way. The extent of the delays seen on the project demonstrate a management – and political leadership if you like – that was consistently out of touch with the reality on the ground for considerably longer than 2 years.

      The idea that a new “Chair of Tfl” – ie Mayor – took over in 2016, and that only from that point did everything go wrong, is bereft of any evidence or understanding about how large construction projects function.

    Not entirely sure what they are, but an eye tooth or two would I gladly have given for the access afforded by the contractors. The relatively low number of images only serves to whet the appetite.
    Thanks to all concerned. Bonus thanks for the shot of the cable to bar transition which I’d been wondering about on and off. As it were.

  3. Nick Howe says:

    Hi, I was wondering if you knew if an entrance has been planned to access the station from Durward Street at the eastern end of the district line concourse? Or is the “temporary” entrance to Whitechapel station going to remain, so if you are approaching the station along Durward street from the east you would need to walk all the way to the western temporary entrance via Durward street?

  4. Barend Köbben says:

    “as these are mainline trains powered by overhead cables — they need a barrier to stop accidents happening” — surely, with third rail power this is just as, if not more, a concern…?
