Minor refurbishment of the station has taken place over in recent years, which has seen the station internally repainted and paved with new flooring, and the CRT screens that displayed train timetables and passenger information were replaced with new LED information boards similar to those in Glasgow Central Station but smaller, in January 2008.

In August 2006 Network Rail revealed that it intended to redevelop Queen Street substantially, making use of the Hanover Street car park area to provide more retail space, and to upgrade the station's entrances, and to provide escalators down to the lower-level platforms – at present there are only steep staircases at either end of Platforms 8/9, and lifts which have to be reached using a circuitous route via the main line platforms.
More plans were unveiled in September 2011 by Network Rail, along with an announcement that the owner of the Buchanan Galleries shopping mall – Land Securities had been chosen as development partner for the station.
This saw the 1970s hotel extension (which until recently fronted the George Square entrance of the station) 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.
 The redevelopment, which was initially scheduled for completion in June 2019, also includes an extension of the high level platforms to accommodate the longer trains that will be introduced as part of the Edinburgh Glasgow Improvement Programme (EGIP).

In 2009, the Scottish Government announced that the Glasgow to Edinburgh via Falkirk Line would be electrified by 2017.
Overhead line electrification lines have been installed on the high level platforms of Queen Street, with Class 380 trains now operating from the station as of December 2017, and Class 385 trains as of Autumn 2018.
As part of this work, the High Level station was closed for 20 weeks (from 20 March to 8 August 2016) to allow 1,800 m (5,900 ft) of track in Queen Street Tunnel (and all of the tracks and platforms in the station itself) to be replaced.
 Services were diverted over various routes during this period, with some trains running to/from the Low Level station and others to/from Glasgow Central station (via Cumbernauld, Coatbridge and Carmyle).

In August 2017, work began on the £120 million redevelopment of the station, which was due to be completed by December 2019, but has now been scheduled to 2020 due to delays in receiving power to go forward with the work.
