LONDON TRANSPORT OVERVIEW
German manufacturer Hering gives RTM its take on its work with Network Rail to extend platforms at Elstree & Borehamwood as part of the Thameslink upgrades, that took just 48 hours.
I
n collaboration with our client, Carillion Rail, and structural
Hering have designed, manufactured and installed a new precast platform extension at Elstree & Borehamwood station.
Passengers at Elstree & Borehamwood station can look forward to longer trains and more seats after two of the station’s platforms were extended by more than 70m each in a single weekend – work which would have taken up to six months using conventional methods.
Carillion was able to draw upon Hering’s vast experience, enabling installation during a very short time frame using our modular precast system. Installation engineers, working closely with a team from Volker Rail, lifted 22
pre-cast
platform sections – each measuring 6m by 3m and weighing 14 tonnes – into place along the Midland Main Line.
The units came to site with a completely fi nished surface, including ‘blacktop’, tactile and textured coping stone, all made from precast concrete. A video of the installation is available on request from the company’s UK offi ce.
The development of the modular precast platform modula®
in 1997 revolutionised
platform construction. The high degree of prefabrication, the factory’s quality guarantee, the diversity of the design and the construction variants permit individual and need-based new development, conversion or alterations to train stations.
All modular systems from Hering are noted for a high degree of prefabrication in the factory, thereby simplifying and speeding up the fi nal assembly at the installation location to a considerable degree. This is not limited to platform systems, since the company also offers modular station canopies and completed an architectural precast facade on Haggerston station, Hackney, in 2010.
The platforms were extended as part of the £6bn Thameslink Programme to improve services on the line from Bedford to Brighton via central London.
Platforms at stations along the Thameslink route are being extended by a combined 4km, ready for the introduction of 50%
engineers, Tata,
longer trains in December 2011 and the introduction of new trains in 2018.
The fi rst longer 12-carriage trains are expected to start calling at the station in December 2018 once a fl eet of new trains has been built and delivered into service.
This latest project adds to the growing portfolio of work Hering have completed in recent years, including at Baker Street station, seven DLR stations, Shepherd’s Bush station and others. All of these stations utilise the company’s bespoke pre-cast platform method and details are available.
As part of a new co-operation agreement with Aspin Foundations, Hering will also produce a ‘slab only’ platform capable of being installed directly onto a pile cap. This will add many advantages to the main contractor and client, including time and money.
It is hoped this new methodology will all but eradicate the need for ‘wet trades’ at future rail platform extensions or new builds. A mock-up of this platform is available upon request.
