HUGE demand for Glasgow Central Station's new behind-the-scenes tours has seen more than 1,000 tickets sold in less than two weeks.

Railway fans are being urged to move quickly if they want to snap up the nine remaining tickets before the tours are completely sold out.

The tickets which are left are for one person only on nine separate tours, so buyers would have to be willing to join up with tour groups on their own.

The available dates, mostly in the new year, are listed on the booking website. Otherwise all the tours are now completely booked out until the end of February.

Tickets costing £10 per person went on sale online on Wednesday November 5 with the first tours getting under way two days later. Around 290 people have already taken part.

They are being run six times a day, from 9am to 7pm, on selected weekdays and during weekends until February 26.

However, fans wanting to purchase more than one ticket will have to wait until March at the earliest, with organisers promising that new dates for March to May will be added to the booking website soon.

A spokesman for Network Rail, who own the station, said: "The tours are almost sold out. At its busiest point the ticket website was receiving 700 hits a minute." The 90-minute excursions are limited to ten people at a time and encompass a climb onto the station's historic glass roof, 40ft above the main concourse, and a tour of the eery catacombs of abandoned Victorian platforms and tunnels far beneath the station.

The tours are led by station staff and were organised after the huge success of a Doors Open Day event in 2013, which took participants onto the station roof. A decision was then taken to expand the tour into a full-time tourist attraction.

Network Rail said there were currently no plans to replicate the success of the tours at Edinburgh Waverley station.
