The Elizabeth line is an underground railway line operating east to west through London and its surrounding areas. It connects stations in the western part of London, such as Reading Station and Heathrow Airport terminals, with Abbey Wood Station or Shenfield Station in the east. Originally consisting of only the Great Western Main Line and the Great Eastern Main Line, a new section was constructed in central London to directly connect these lines as part of the “Crossrail” project. After the opening of this new section, the line was renamed the “Elizabeth line” as a collective name. This report details the findings from an inspection of the line that the author conducted.
