Network Rail, Govia Thameslink Railway and Southern are working together to improve performance on one of the most congested railways in the country.
More than 3,000 trains a day run on the railway linking London and the Sussex Coast and in recent years, as demand has grown, performance has declined. This also affects Thameslink services north of London.
The rebuilding of London Bridge as part of the Thameslink Programme, which will ultimately bring vitally needed extra capacity to the route, has added an additional strain with fewer routes into and out of the station.
More than a million people use London Bridge every week, and keeping them moving whilst rebuilding the station has been a huge challenge.
RJ Power Group has been involved with the upgrade of HV and DC Power to London Bridge, Sussex route and more recently the traction power supply at Three Bridges Depot.
