Station refurbishment
engineering, to design an air-handling unit installation and removal system (Airs). The Airs would be attached to a standard maintenance wagon and, along with the air-handling unit, transported to a station where it would be used to lift and install the air-handling units onto the support structures attached to the tunnel ceilings. Follow-up work included analysis of the vibration that the air-handling unit would experience during transportation, as well as the assessment of tunnel size clearances. Stability of the system during installation of the air-handling units was a key issue, as the heavy mass is positioned over the platform while being lifted into the roof of the tunnel ceiling. The Airs was designed so that the station platform was not used to support any weight during installation and removal, saving considerable time in not having to protect the platform and eliminating the risk from damage, which could affect train operations.
‘LU knew that the PAHUs would provide the cooling needed, but how to get the units into the right position had to be carefully thought through. By taking this project forward, a cooler environment is now becoming a reality for both passengers and staff on the London Underground network,’ Wilson adds.
SHOP UNTIL YOU DROP! M
ulti-million pound investments in station redevelopment are bringing new opportunities for stations to generate income by leasing retail space. Network Rail figures show that trading figures for station retailers have outstripped the high street
throughout the recession and consider to see growth. King’s Cross opened its new concourse to the public earlier this year, transforming the
passenger experience by bringing two dozen retail outlets to a station that only had a handful of shops and food kiosks before. Passengers at King’s Cross can now while away their time eating and drinking in Prezzo, relaxing in Starbucks, shopping in Watermark or revisiting old favourites such as M&S or WH Smith. Ian Fry, Network Rail’s King’s Cross
programme director, says: ‘Research tells us that passengers consistently rate high-quality facilities alongside convenient retail and catering as important station priorities. The new concourse at King’s Cross is designed to provide those facilities which will make journeys easier for passengers as well as appealing to those who like to combine their travel with a bit of shopping, eating or drinking.’ King’s Cross is not the only big station to begin rivalling local shopping centres with its
retail opportunities, St Pancras was transformed five years ago, while Waterloo has just had a new balcony added with an extra 20,000 sq ft of retail space. New retailers at Waterloo include Yo! Sushi, Fat Face, Hotel Chocolat, Oliver Bonas, Links of London, Thomas Pink and Joules. Further additions will include Italian eatery, Carluccio’s, Kiehl’s Sports Bar & Grill, Benugo and new concept bar The Cabin, which will be opening soon. Once all the new units are open, the retail capacity within the station will total 55,000 sq ft incorporating 38 stores.
