The upgrade and improvement of existing railway lines across the UK has been and still is a priority of the existing administration, as they carry 50% more passengers than they did 10 years ago. In Scotland, the latest figures estimate a total investment of around £1 billion of enhancements within Control Period 5, which includes the Edinburgh–Glasgow Improvement Programme (Egip). This paper focuses on the design and construction of a number of interfaces within Egip, from platform extensions to bridge reconstructions and changes to existing tunnels, with the goal of having the main line between Edinburgh and Glasgow electrified and with train capacity significantly enhanced. In order to minimise any negative impact that the proposed electrification could have on biodiversity, as well as from a suitability point of view, an attempt was made in the design, whenever possible, to accommodate and reuse existing structures as opposed to rendering the existing infrastructure completely obsolete.

保留铁路升级的基础系统

整个英国现有铁路线的升级和改善一直是并且仍然是现任政府的首要任务，因为与10年前相比，其载客量增加了50％。在苏格兰，最新数据估计在控制期5内，包括爱丁堡-格拉斯哥改善计划（Egip）在内的总投资约为10亿英镑。本文着重于Egip内许多接口的设计和构建，从平台扩展到桥梁改造以及对现有隧道的更改，目的是使爱丁堡和格拉斯哥之间的干线电气化，并显着提高列车的通行能力。为了最大程度地减少拟议的电气化对生物多样性的负面影响，以及从适用性的角度，
