Sentinel Hill Station
Sentinel Hill Station is the third oldest and most strategic station of the CRS. It is the only station in Colonia that connects four railways - the Piccadilly Line, Jubilee Line, Metro Line and Cambridge Line. The station was originally built in December 2016 as an additional stop to the south on the Piccadilly Line from Dark Oak Mountain Fortress (DOMF). The station became the first hub station when the Jubilee Line was added as the second railway line. It was at this time that the railways were given unique names to differentiate and identify them. The original station was built just slightly west of Sentinel Hill Tower but was moved further to the west in 2017 to accommodate both the rerouting of the Piccadilly Line and the new Metro Line, which would share the same platform. In 2019 the Cambridge Line was added underground to the station. Currently, four railways branch out of Sentinel Hill Station in 8 different directions.
