The Jura Foot Line or Jura South Foot Line, is a railway line in Switzerland. It runs from Olten along the foot of the southern Jura range through Solothurn, Grenchen, Biel/Bienne, Neuchâtel, Yverdon-les-Bains and Morges to Lausanne. It is one of two routes used by intercity trains between Geneva and Zürich. The other is the Midland line which connects Olten via Langenthal, Burgdorf, Bern, Fribourg, Lausanne to Morges. The line was built by five railway companies, which after several mergers were absorbed into the Swiss Federal Railways in 1903.
