The 44 SBB Intercity tilting trains "ICN", built between 1999 and 2005, will undergo a major overhaul at the Yverdon-les-Bains plant over the next few years in order to be fit for their second half of life. The prototype of the rebuild is RABDe 500 # 004, which has already been undergoing treatment for some time. Here the train, together with RABDe 500 # 015 in multiple control, is on a test run as train 97331 from Biel to Solothurn, between Bettlach and Selzach on the Jura-Südfuss main line.
