Abstract

Abstract: The Edinburgh Glasgow Improvement Programme (EGIP) is a major part of railway investment in Scotland to electrify the main line between the two cities, increase travel capacity and reduce journey times. This paper focusses on the design and construction of a number of components within EGIP, including bridge reconstructions, platform extensions, and changes to existing tunnels. Given the limited records and information on most of the existing structures, extensive ground investigations (GI) have been completed to facilitate the design. In most cases a comparison between the effects of the proposed changes and the existing configuration has been undertaken, based on the interpretation of the findings of the intrusive investigation and record drawings, as well as the proposed and existing loadings. As the structures, particularly the bridges, are generally not compliant with current standards, the design approach was based on the principle that the new arrangement will not have a significant detrimental effect on existing stability. This methodology has been confirmed and accepted by Network Rail as Asset Owner.
