| Why do we need a Light Rail Solution ?
|
|
| Light Rail offers a new opportunity to progress public transport
systems into congested urban areas. These areas are expensive to build into
because of the prohibitive cost of moving the infrastructure beneath the roads.
Light Rail with its revolutionary rail profile, LR55, offers a solution to this problem by avoiding the need to reconstuct the road prior to laying rail.
|
|
| LR55 is a revolutionary system of laying light rail track using 2 separate prefabricated foundation troughs, 380mm wide and 180mm deep sitting in
trenches only 400mm wide and 200mm deep. Special road reinforcement is NOT required allowing rapid installation of 500 metres per week and allowing Utilities ready access to pipework and cables underneath.

The rails are weldable low profile rail grade steel weighing 55kg per metre delivered in
18 metre lengths with a 12m radius curve and Switchings and Crossings to match.
The rails are bonded using polyurethane, a two pack polymer that is mixed and injected to bond the rails into the foundation troughs and to provide the resilience for load spreading and vibration reduction.
The troughs are precast, pre-stressed concrete and are delivered in lengths of up to 6 metres.
This robust structure can take up to 80 tonne axles weight and has been proved in Sheffield since 1996.
