a programme of works carried out to enable the Class 320 units to work through the station in passenger service. The class 320 and 318 units between them now provide the majority of Argyle Line services, with most 334s having moved to operate the Airdrie-Bathgate Rail Link. Flooding of the Low-Level line Over the Christmas festive period of 1994, on 11 December, torrential rain caused the River Kelvin to burst its banks at the closed Kelvinbridge station, with the water making its way through the disused tunnels to and the Low-Level station, which was completely submerged by the resultant flash flood. It was closed until 24 September 1995 while repairs were made. In August 2002, torrential rain flooded out the low-level stations from through to for a number of weeks. Most services were routed to the high-level platforms, or to Queen Street station. The 2002 Glasgow floods had a number of other effects, causing a cryptospiridium outbreak in Glasgow's water supply. 1980s redevelopment The high-level station's facilities were substantially redeveloped in the mid-1980s. The old ticket office / train information building was replaced in 1985 by an all-new Travel Centre adjacent to the Gordon Street entrance. By 1986 a large electro-mechanical destination board at the end of the platforms, with a smaller repeater board at the western side of the concourse, had replaced the former manually operated train-information boards. The old booking office / train information building was retained and redeveloped into shops, eateries and an upstairs bar/restaurant, and the station was re-floored in marble. During this redevelopment the staffed ticket barriers at Platforms 1 to 8 were removed and the yellow ticket automatic barriers were removed from Platforms 9 to 13 (now 15). 1998–2005 refurbishment In 1998, a five-year renovation programme was initiated by Railtrack, which saw the trainshed completely re-roofed and internally refurbished by Bovis Lend Lease – which also included the restoration of Hielanman's Umbrella. The 1980s vintage mechanical pixel-style destination boards were later replaced around 2005 with an array of LED-style destination boards. The final improvement, the upgrading of the upstairs restaurant area, was completed in 2005. 21st century developments Layout Platform 1 is at the east end and platform 15 is located at the west end of the station with platforms 16 and 17 being directly underneath the station's high level platforms. Platforms 1 and 2 are usually used by longer distance cross-border services operated
