The SBB RABDe 500, also known as the ICN,[a] is a Swiss high speed passenger EMU, which was introduced in 2000, in time for Expo.02 held in western Switzerland in 2002.

Its maximum speed is 200 km/h (125 mph), and it employs tilting technology, which allows it to travel through curvy routes faster than non-tilting trains.

The RABDe 500 often run with two complete compositions, each with seven carriages and a seating capacity of 480,[3] both including a dining car.

[5] The trains were intended for use on the Jura Foot Line; adopting tilting technology allowed SBB to defer track upgrades over the route.

This practice ceased with the December 2017 timetable changes, in which all IC and IR services gained numbers and the ICN category was eliminated.

[16] All forty-four RABDe 500 trains are named, mostly after famous Swiss scholars, artists, writers, politicians, engineers, and architects.

Each train bears the portrait of its namesake, painted by Bernese painter Martin Fivian, in the third car (first class and restaurant).
