demolished and replaced by a glass atrium. The previous plans of developing the airspace rights above the North Hanover Street car park into an expanded retail and restaurant area will be carried forward – and will form part of the proposed extension to the Buchanan Galleries, which will gain direct access to the station concourse. In August 2017, work began on the £120 million redevelopment of the station, which at the time was expected to be completed by December 2019, but was pushed back until 2020 due to delays in receiving power to go forward with the work. Platforms 2 through 5 were subsequently extended in 2019 to accommodate longer trains introduced as part of the Edinburgh to Glasgow Improvement Programme (EGIP). Demolition of surrounding buildings was completed in October 2018 to accommodate the lengthened platforms and expanded concourse. Following demolition of the surrounding Consort House buildings, the original Victorian era train shed (the large curved glass roof of the station) was uncovered after more than 40 years. The shed is a Category A Listed Structure, and subsequently work on the station was undertaken with care to integrate the historic structure into its new surroundings. The work was officially completed on 4 October 2021. This also marks the end of EGIP. In May 2021, a planning proposal was submitted to add a new plaza and mezzanine on the North Hanover Street side of the station. , the decision is still pending.
