The Secretary of State at the Department for Transport approved the Capacity Scheme in February 2018 and Network Rail have received tenders for a Design and Build contract that they hope to have confirmed by the Department for Transport before the end of 2020 when the contract can be let. Construction should start in early 2022 with an intention to have it complete by autumn 2023. Any new train services are not expected to be able to operate before the December timetable changes, and possibly later.
