The Northern ITT was published in February 2015. At that time the Network Rail CP5 Enhancements Delivery Plan, December 2014 version, had the GRIP 6 complete milestones for the Oxford Road and Piccadilly schemes as December 2018, as part of the North of England Programmes (LNW) project. They were annotated "Configuration State 7 - Delivers the interventions to enable the operation of the proposed timetable in December 2018". The Ordsall Chord had a GRIP 6 complete milestone of December 2016, as had electrification from Manchester to Preston and Victoria to Stalybridge. These were annotated "Configuration State 5 - Delivers the interventions to enable the operation of the proposed timetable in December 2016".
The TSRs attached to ITT specified service enhancements in two stages, for December 2017 and December 2019. Most of the changes related to the Ordsall Chord were in the 2017 TSRs, but the Bradford - Manchester Airport service, via the Chord, was not required until December 2019. It is a reasonable deduction that this service was considered dependent on the capacity enhancement provided by Oxford Road and Piccadilly schemes.
The Northern franchise award to Arriva
was announced on 09 December 2015 and signature of the contract
was confirmed on 23 December 2015. The franchise agreement
was dated 22 December 2015. The TSRs attached to it included all the Northern Hub service enhancements from the ITT, with the same introduction dates.
The Hendy report
was published on 25 November 2015. It did not specifically reference the Oxford Road and Piccadilly schemes, but the Northern Hub project as a whole remained in CP5 with completion shown as December 2019. The CP5 Enhancements Delivery Plan was not updated until March 2016 to show the Hendy changes; at that time the Oxford Road and Piccadilly schemes (now designated "Package C") were still included but with the milestones changed to "Subject to TWAO".
It is not credible that, in the short time available between Hendy publication and contract signature, the Arriva bid was reworked. It can be deduced that the redacted Infrastructure Assumptions Document (IAD) included Oxford Road and Piccadilly completion by December 2019, evidenced by the lack of change between the ITT and franchise agreement TSRs.
In December 2016, Northern and Porterbrook announced the conversion of 8 of Northern's Class 319 EMUs to Class 769 bi-modes, with the support of the Rail North Partnership (i.e. DfT). These were to be used on services from Wigan to Stalybridge and Alderley Edge. From this it can be deduced that the IAD included Lostock to Wigan and Victoria to Stalybridge electrification by December 2017, to enable Northern to use the 319s included in the original fleet plan. The 769s are still not in service, forcing Northern to use DMUs on these routes and causing the DMU fleet to be overstretched.
In July 2017 DfT announced cancellation of the project to electrify the Windermere branch. In December 2018 Northern ordered an additional three Class 195 DMUs to operate Windermere services. From this it can be deduced that the IAD included Windermere electrification, which would have enabled Northern to use Class 331 EMUs per its original fleet plan.
