Network Rail to modernise signalling system

Earlier this year, Network Rail began the next phase of their much anticipated Railway Upgrade Plan, a project that involves modernising the current system by updating a number of signals across the Norwich, Yarmouth and Lowestoft network.

The ambitious £68 million investment programme includes the installation of 22 power operated points, a computer based signalling control system as well as 66 new colour-light LED signals.

UltraCrete offers a range of rail maintenance and installation products such as QC10 fast set rapid strength concrete, which is ideal for the installation of heavy duty signals, like the LED signals being used by Network Rail. Independently tested by an approved third party, QC10 is proven to provide a first time, permanent installation, can be applied from depths of 30 – 250mm and is trafficked in as little as 2 hours, allowing contractors to move on to another project quickly, increasing productivity and helping to meet tight deadlines.

The Railway Upgrade Plan also involves upgrading the current manual operated level crossings with a modern, remote controlled system. To guarantee an effortless and lasting installation, UltraCrete advises installing rail bolts with HF high flow precision grout.

Suitable for the infill of voids from 10 – 100mm, HF can be pumped or poured for ease of application and boasts an impressive compressive strength of 29N/mm² in just 24 hours. What’s more, HF’s formulation doesn’t contain any reactive materials which eliminates any possibility of corrosion, giving you peace of mind that rail bolts installed with HF are designed to last.

Should any concrete sleepers become damaged during signal improvements, UltraCrete QC10 F flowable fast set rapid strength concrete is on hand to carry out quick and permanent repairs. Fibre modified for added strength, QC10 F achieves a 20N/mm² compressive strength after just 90 minutes, is easy to mix and literally pours from the bucket facilitating a speedy application.

QC10 fast set rapid strength concrete, HF high flow precision grout and QC10 F flowable fast set rapid strength concrete are just three products in UltraCrete’s Rail Refurbishment Solutions range. Each product in the range can be found on the London Underground compliance register, have been independently tested and are proven to provide first time permanent, fast setting properties to minimise your possession time and save you money.
