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.
The VIPA DRS offers low vertical stiffness and is ideally suited to applications where this level of track support resilience is required. It combines the proven technology of the Pandrol e-Clip in a baseplated system that offers adjustments and is easy to maintain.
In tandem with the delivery of the VIPA DRS is Pandrol’s Vanguard fastening system. The significant reduction of vibration and secondary noise makes it ideal for applications in the most sensitive areas to these environmental concerns. As this was the first deployment of the Vanguard in Malaysia, Pandrol supported the local team with on-site demonstrations on how to install and maintain the fastening system.
A version of Vanguard was designed which would 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.
