A government report scrutinising scheme鈥檚 business case will be handed down next month

A crucial report probing Crossrail 2鈥檚 business case is set to be unveiled next month, according to documents published by Transport for London (TfL).

Papers published ahead of next week鈥檚 TfL board meeting reveal the Infrastructure and Project Authority (IPA), which is based in the Cabinet Office, is reviewing several features of the Crossrail 2鈥檚 outline business case.

TfL commissioner Mike Brown said the review is the 鈥渘ext step鈥 for the scheme following the submission of Crossrail 2鈥檚 strategic outline business case (SOBC) to the government in June.

The process is being carried out by the IPA鈥檚 Project Assessment Review (PAR) team, according to Brown. 

Brown said: 鈥淭he purpose of the PAR is to advise the Department for Transport鈥檚 Board Investment and Commercial Committee, TfL鈥檚 Programmes and Investment Committee and HM Treasury鈥檚 Major Projects Review Group on the quality and strength of 2019 SOBC.

鈥淒uring the review, the PAR team will be looking at a number of lines of inquiry, including funding and finance, benefits, deliverability, assurance and governance. A report on the review鈥檚 findings will be produced in early October.鈥

Brown also revealed that TfL鈥檚 Independent Investment Programme Advisory Group had carried out an independent review of the proposed 鈥渁ssurance framework鈥 for the project over the summer.

He said this report would feed into the work of the Independent Assurance Panel, which provides independent assurance to the Crossrail 2 sponsors. 

Earlier this year, Crossrail 2 managing director Mich猫le Dix revealed that her team had been targeting an opening date in 2033 鈥 but that delays to Crossrail 1 may now make this unachievable.

She said: 鈥淚deally, we wanted it to be operational by the time HS2 phase 2 came down from Manchester to Euston.

鈥淎 date we were aiming for was 2033, but I think it鈥檚 more realistic to believe it might have gone back a bit simply because of Crossrail 1鈥檚 delay.鈥 

The proposed Crossrail 2 route would see trains run from nine stations in Surrey to three in Hertfordshire, providing a new north-south rail link across London.
