The Swiss Federal Railways SBB set itself a target in the mid-nineties, to reduce the journey time on the major intercity connections. However indications showed that the necessary improvements on these curvaceous lines would require a substantial investment. A more cost effective solution was finally selected, using tilt-train-technology, which enables higher average speeds to be attained on existing lines. Therefore since 2001, on the two main lines of the Swiss Railways, 24 ICN Tilting Trains, have been in regular service operations.
In June 2001, based upon the successful performance of the existing ICN fleet, the SBB awarded the consortium Bombardier Transportation, consortium leader, and Alstom a further order for 10 additional ICN trainsets.These trainsets are now in service on the two passenger lines Geneva-Lausanne-Biel-Delémont-Basel and Biel-Zürich.
