Winterthur railway station
Winterthur is Switzerland's fifth busiest station, and is a major node between Switzerland's largest railway nucleus in Zürich and places in Eastern Switzerland (such as St. Gallen and Schaffhausen), as well as Germany (Munich), and Austria (Vorarlberg). The station is served by trains on Zürich's suburban S-Bahn network, as well as by regional and intercity trains, with most through passenger trains making a stop. It is also connected with Zürich's airport railway station Zürich Flughafen, which can be reached in about 15 minutes about every 8 minutes. Zürich Hauptbahnhof can be reached with up to 16 direct connections per hour and the fastest connection takes only 22 minutes (S12). The station has 9 standard gauge platforms (numbered 1-9).
Australian railway signalling
Projected traffic density warranted the introduction of additional signal indications. One of these was a small green light under the two main red lights of a Stop signal, indicating Low Speed. The Low Speed indication was provided in the Underground City Railway from its opening on 28 February 1932. The standard speed restriction imposed by train stops with the Low Speed indication was originally 17 mph. However, at some locations, the maximum permissible speed is as low as 5 mph, subject to local conditions. In the Underground City and Eastern Suburbs railway lines, a speed restriction of 30 mph also applies to the Caution indication. The train stops can be seen dropping as the signals step-up to Medium. Closely spaced 'multi home signals', similar to those used on the London Underground, are also a feature of the Underground City and Eastern Suburbs lines. Speed control by intermediate train stops, based on Mr Byles' system, was introduced on the London Underground following the accident at Moorgate on 28 February 1975, in which 43 people were killed. These are spread out along the platform at major stations, mostly on the City Circle. When the signal at the end of platform is at stop, they will only drop when the train reaches a predetermined speed, which is lower as the train gets closer to the end of the platform. The last trip will only drop when the train is at around 5 km/h.
