This document provides an overview of the modernization of the Glasgow Subway system in Scotland. It discusses the origins and construction history of the subway, describes the 1970s modernization program, and outlines the current modernization program that began in 2015. The current program involves introducing new rolling stock and control systems, including communications-based train control to allow for unattended train operation, installing platform screen doors, upgrading stations and other infrastructure, and replacing the operational control center. The document provides status updates on the progress of the modernization work.
