Here are some facts you may not know about Queen Street Station.
It is believed that the quarry was established during the medieval period but it was in-filled during the 1840s and Queen Street Station built on the site.
Artist William Simpson grew up in North Frederick Street and knew the area well. He particularly remembered that the mound at the edge of Bell's Quarry was a favourite spot for flying kites, and also for stone-throwing battles between local boys.
Originally named Dundas Street Station, Queen Street Station opened in 1842 as the Glasgow terminus of the Edinburgh and Glasgow Railway.
A major obstacle was the Cowlairs Incline, a steep slope with a gradient of 1 in 46 which required early trains to be hauled from the station by means of a steam-driven winding cable.
In 1928 there was a railway accident causing three fatalities when a train leaving the station slipped to a standstill and rolled back into another train. Modern diesel trains have no difficulty with the climb.
In 1953, an average of 8345 passengers a day used Queen Street high level station, while 15,120 passengers used the low level station.
Services for Helensburgh, the West Highland Line, Edinburgh and England via the east coast departed from the station. During the winter months Buchanan Street Station was closed on Sundays and its traffic was re-routed to Queen Street.
Although the station had been described as a "fairy palace" when it opened in 1842, by the 1950s "many passengers saw Queen Street as a dismal dirty place to begin a journey". The station was modernised in 1965.
