The Argyle Line is a suburban railway located in West Central Scotland. The line serves the commercial and shopping districts of Glasgow's central area, and connects towns from West Dunbartonshire to South Lanarkshire. Named for Glasgow's Argyle Street, the line uses the earlier cut-and-cover tunnel running beneath that thoroughfare.
