Continental Train Platform

Continental Train Platform
Demonstrated System: Arches
Architect: Nicholas Grimshaw and Partners
Location: Waterloo Station, London
Date: 1993

Constructed alongside an existing Waterloo Station, this new platform accepts the old Windsor lines. It includes basement car parking and a new train shed roof. The roof consists of 37 prismatic, three pinned bow string arches covering approximately 400 meters, the entire length of the trains. The upper pin of the arches is where the external inverted truss with twin tie rods convert to an internal bow string truss with a single lower tie rod and twin large diameter steel tubes at the top. The roof effectively follows the stress diagram for the structure, and responds well to the movement in the supports.
