Overhead line electrification of existing railway lines is an essential contribution to sustainable, low-emissions public transport. Civil engineering enables a programme of electrification through clearance of the route and the protection of the public from live overhead wires. This paper considers the key civil engineering works carried out as part of the £3 billion Great Western railway electrification programme between 2012 and 2019, and explains the primary interfacing considerations civil engineers had to address. Lessons learned from the programme include the logistical, stakeholder, safety and reliability factors addressed by the civil engineering teams that delivered the works.

英国大西部铁路电气化：土木工程

现有铁路线的架空线电气化对可持续，低排放的公共交通至关重要。土木工程通过清除路线和保护公众免受带电架空电线的影响，实现电气化计划。本文考虑了2012年至2019年30亿英镑的Great Western铁路电气化计划的一部分所进行的关键土木工程，并解释了土木工程师必须解决的主要接口问题。从该计划中学到的教训包括交付工程的土木工程团队所解决的后勤，利益相关者，安全性和可靠性因素。
