Great Western Main Line Route Structures Gazetteer

The purpose of this document is to provide a baseline description and assessment of the significance of every railway structure and building along the lines affected by the Great Western Main Line Electrification Project.

The Gazetteer is intended to be used in conjunction with the its companion volume, the History and Significance of the Great Western Main Line. That document provides important context for readers of this Gazetteer by explaining the historic development of the lines, the main phases of alteration, the types of structures found on them, and the significance of the structures in the context of other railway engineering. It is particularly useful for understanding more about the standard and generic types of structure which are a characteristic of the lines (for example, Brunel’s triple-arch overbridges).
