How much is Crossrail going to cost? Building reveals what we know about the rail project’s delay 


While the original opening date of Crossrail has more than come and gone, the project's central section now finally has an opening date 24 May 2022.

But there are still plenty of questions around how the scheme fell so far behind.

As Transport for London (TfL), the Department for Transport (DfT) and Crossrail Ltd close in on completing the project, there are queries around how much it is all going to cost and what got the mega-project into this position in the first place.

Take a look at what we know so far.

When was the line due to open?

An update by Westminster council let slip online that the central section of Crossrail was scheduled to open on 9 December 2018, as part of its follow-up to the decision to reject the pedestrianisation of Oxford Street.

What is to blame for Crossrail’s delay?

When announcing the delay Crossrail said the schedule has been revised “to complete the final infrastructure and extensive testing required”.

Subsequently, the first chief executive of Crossrail Rob Holden blamed a decision to delay procurement of rolling stock for the scheme’s failure to hit its December 2018 opening date. A TfL spokesperson denied this saying: “The procurement of the trains has had no impact on the delayed opening of the central section.”

Mark Wild has previously blamed the tunnelling for delays at Bond Street and has said the original plan to get the scheme open was “fantasy”.

The delay to the summer 2021 opening date was at least partially blamed on the covid-19 pandemic.

Were there warning signs?

Nearly two months before the delay to Crossrail was confirmed, the Infrastructure Projects Authority flagged potential issues with the scheme.

In its 2018 Annual Report, the Infrastructure Projects Authority gave Crossrail an amber delivery confidence assessment meaning it was looking at a cost or schedule overrun if “significant issues” were not addressed. It was the first time the project has received a rating below a green category in the six years the report has been produced.

How much is Crossrail going to cost?

At the moment the official known cost has topped the £18.6bn-mark. 

While the 2020 bailout was confirmed to bring the total thus far to £18.6bn - though the project has maintained that it will need up to the £1.1bn it was asking for when it was handed £825m in December 2020.

The latest estimate on the funding shortfall is £174m.

On 10 December 2018 it was revealed that Crossrail was set to cost up to an additional £2bn with the Greater London Authority set to grant TfL a £1.4bn loan to finish off the scheme.

When is Crossrail now due to open?

Crossrail has confirmed that central section trains will start running on 24 May 2022. Full line services are expected to be within the next 12 months.

Crossrail confirmed it would miss its proposed central section opening date of summer 2021, blaming the covid-19 pandemic, among other factors, for the latest delays. It then said it would open in the first half of this year, which was narrowed to be between February and June late in 2021.

Bond Street will not open in line with the rest of the central London stations and is expected to do so three months later.

Back in April 2019 Crosrail boss Mark Wild saidd the scheme would open some time between October 2020 and March 2021. 

When the delay was first announched it was meant to open before the end of autumn 2019, but then the London Assembly put a cat among the pigeons suggesting Crossrail may not open until December 2019 – a full 12 months later than it was originally due to open.
