back into another train. Modern diesel and electric trains have no difficulty with the climb. The adjacent station of the rival Caledonian Railway closed on 7 November 1966 as a result of the Beeching cuts and its services to Stirling, Perth, Inverness, Dundee and Aberdeen transferred to Queen Street. This caused difficulties with longer trains, as Queen Street is in a confined position between George Square and the tunnel. Buchanan Street was demolished the following year in 1967. In the 1980s, HSTs were used on Cross Country and East Coast services run by InterCity, having to use Platform 7 with the end of the train being close to the tunnel mouth. Minor refurbishments of the station took place throughout the 2000s, which saw the station internally repainted and paved with new flooring, and the CRT screens that displayed train timetables and passenger information replaced with new LED information boards similar to those in Glasgow Central Station but smaller, in January 2008. The station received new Eco LED screens provided by Infotec Displays in 2020. 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 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). Expansion 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. 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 alongside Henderson Group. This saw the 1970s hotel extension (which until recently fronted the George Square entrance of the station)
