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).
Olten–Bern railway
On 12 December 2004, a new high-speed rail line was opened between Mattstetten and Rothrist as part of the comprehensive Rail 2000 project. It is almost long, with one branch to Solothurn and the Jura foot railway line to Neuchâtel, Yverdon and Geneva. The line has a maximum speed of 200 kilometers per hour and reduced the travel time between major Swiss hubs of Bern, Basel and Zurich to under an hour allowing the regular interval timetable (German: "Taktfahrplan") to be put into effect, where both express and stopping trains on all lines arrive and leave on the hour at Bern and Zurich stations, allowing a great number of convenient connections. The line was the longest new line built in Switzerland since 1926. Construction began in April 1996 and was planned to be completed date in 2005. On 30 April 2004, the last piece of rail was put into place at the Bern-Solothurn canton border at Inkwil on the connection to Solothurn.
