If the Tube's history happened in Zürich: - Metropolitan Line: Built to connect the Hauptbahnhof with the main city destinations, later extended far north to Dübendorf - District Line: Built to complete a loop between all railwaysstations in the city. During construction there wasn't much money, thus the line built ceveral extenstions to basically everywhere - Stauffacher and City Line: Provides a slight alternative to the routes of the District and Metropolitan - Circle: Runs a circular service around the Metropolitan, District and Stauffacher and City Lines - Central Line: Straight, deep-underground connection through the heart of the city, later extended on both ends to include suburban services - Piccadilly Line: Built as a new line serving underused parts of the city, later extended to serve the airport - Northern Line: Mess of different lines built at different elevations, all cobbeled together to provide an extensive east-west service - Bakerloo Line: Runs through lesser populated parts of the city and supports the Northern Line in the east-west corridor - Victoria Line: Modern, well-thought-out east-west connection trough the heart of the city, now overcrowded - Bahnhof and Bellvue Line: Cross-Limmat connection between the two main hubs of the city - Jubliäum Line: Modern line built to serve new hip places like Europaallee - Overground: Collection of railwaylines through the city providing a loop service - Trams: Serve an underground-less area in the north of the city - Cabelcar: Connects the two sides of the lake but is slower than just taking the train - Spyri Line: Top Modern connection from Baden in Aargau all the way to Winterthur through the heart of the city, providing interchange with the rest of the Underground
