A world of knowledge
Hong Kong Airport Express, China
The Airport Express is one of the lines of the Hong Kong MTR system. It links the principal urban areas with the Hong Kong International Airport and the AsiaWorld–Expo exhibition and convention centre. The track work comprises a complex variety of trackforms constructed with Pandrol’s e-clip fastening. The turnouts were designed with an adaption of the VIPA DRS. The Depot ballasted track is constructed with Pandrol PR fastenings.
One of the most dramatic features of the railway are the Tsing Ma Bridge, which carries two tracks in an all steel box with a six lane highway on the surface, and the Ma Wang viaduct. The Tsing Ma Bridge spans a 2km gap with a shipping navigation clearance of 62 metres. Pandrol worked with VAE to develop the Rail Movement Joint for the bridge using a Pandrol zero long restraint system to optimise reliability and ease of maintenance.
Klang Valley MRT
In Kuala Lumpur, the Klang Valley MRT system forms the first part of the capital’s new integrated transport system. Line 1 begins from Sungai Buloh, located to the north-west of Kuala Lumpur, and runs through the city centre of Malaysia’s capital city before ending in Kajang, a fast developing town to the south-east of the city. The three new lines of KVMRT comprise more than 140 km of track, serving a corridor with an estimated population of 1.2 million people.
Working in close partnership with Mitsubishi Heavy Industries (MHI) to understand the railway requirements, Pandrol proposed their VIPA DRS fastening system for the mainline areas, while recommending the VANGUARD system for the high attenuation areas. A version of the Vanguard system was designed which will retrofit onto the VIPA DRS baseplate while maintaining the same rail position and inclination. This means that in the future, if areas on the metro route become developed and the track needs to be upgraded to provide more protection, this can be done speedily, easily and economically.
