Abstract: Network Rail's (formerly Railtrack's) Cross Country Route Modernisation (CCRM) Project was conceived to enhance existing railway infrastructure to enable the latest generation of trains to fulfil their performance potential. In order to achieve the desired line speed increases, many at grade pedestrian crossings needed to be replaced with footbridges or subways to comply with health and safety guidelines. Network Rail contracted the provision of new structures in Midlands Zone to Birse Rail Ltd via the Structures Framework Contract. When the CCRM Project is complete Birse will have installed 23 new footbridges and 3 new subways. The subject of this case study will be Rangeway subway, which now carries a public footpath under the Derby to Birmingham line near Kingsbury in North Warwickshire. The subway consists of a 3 metre wide reinforced concrete box with integral wing walls and approach slab. It was constructed 55 metres from the railway prior to the embankment being excavated and it being slid into position using the Brambles system during an Outside Rules Of The Route (OROR) possession. The slide path crossed the route of a medium pressure oil pipeline from the nearby Kingsbury Oil Depot. The case study will include the planning, design and construction aspects of the scheme. During the planning and design stages, possession and track removal/reinstatement requirements were established and Her Majesty's Railway Inspectorate (HMRI), Local Authority, oil pipeline owner's and Environment Agency requirements were all addressed. As the main possession approached, a contractual issue with one of the pipelines threatened to compromise the project. Birse Rail's construction management team therefore revised their programme to ensure the changes were accommodated without comprising safety, quality, the environment or the OROR possession.
