Track renewals don’t mean the platform has to stay out of gauge.
Seven Sisters is a National Rail, London Overground and London Underground Victoria line station in the Seven Sisters area of the London Borough of Haringey, north London. After essential track renewal work to keep services running safely and reliably, the platforms were out of gauge.
Our adjustable platform upgrade system put to the test.
Having previously installed the Dura Platform 40 in 2019 with interim offsets, Principal Contractor Hammond was able to utilise their flexible Mountbridge™ design featuring Dura Platform GRP panels by raising the platform to meet the new track PTI requirements. Keeping passenger disruption to a minimum whilst maintaining safety, this combination of GRP Dura Platforms and Mountbridge™ System is the only solution of achieving these kinds of developments.
X and Y movement by +90 and -60
In a perfect scenario, station platforms would be uniformly straight, featuring consistent heights and offsets, accommodating a single train type, and eliminating the need to account for dynamic gauge requirements. However, the reality is that the majority of stations don’t meet these conditions, so allowance for adjustability and the ability to actually perform it in a real world scenario are paramount. At Seven Sister, the X and Y of both platforms were moved by +90 and -60, bringing them back into gauge in just 24 hours, keeping passenger disruption to an absolute minimum.
