Unipart Dorman supports Sheffield’s new dual voltage SuperTram Network

with iLS

Tags: iLS Infrastructure Value - Innovation Unipart Dorman

The project includes the electrification of the line between Sheffield and Rotherham to 750 V, new tram-train platforms at Rotherham Central and Parkgate, re-profiling of the Supertram network and the construction of the Tinsley Chord – a 160-metre section of track linking the light rail network to the main line network.

New dual voltage tram-train vehicles have been sourced from Vossloh and are able to operate under both the 750 V Supertram catenary and the standard 25 kV used on the national rail network. Unlike a typical tram, the new vehicles also feature main line signalling and protection systems, such as TPWS and GSM-R.

Unipart Dorman has been working with Carillion and have supplied 5 iLS (integrated Lightweight Signals) to the network.  This represents a key milestone for Unipart Dorman as this is the first installation of our iLS on a ‘light railway network’.

By selecting the iLS the Sheffield SuperTram Network will share the same benefits as the mainline network, where our highly reliable LED signals have delivered over 48million fault free operational hours over the last decade.

Network Rail has also recently declared our iLS self cleaning, thus generating further savings which the Sheffield SuperTram Network will also benefit from.  The iLS can be installed in as little as 20 minutes, generating further essential installation time savings. 

LED signals from Unipart Dorman are designed with safety in mind. The combination of time saved during installation and the fact that they are maintenance free, plays a major role in increasing worker safety.
