IC 2020: 8 - 14 May 2019 Testing phase

From 8 to 14 May 2019, modernised cars carried out test runs from Olten to Eastern Switzerland, Central Switzerland and French-speaking Switzerland.

These test runs made it possible to carry out a vast battery of tests including the new intelligent retractable step equipping the cars of type AD. The smart retractable step covers the space between the platform edge and the vehicle to allow autonomous access to the vehicle as required by the Equality Act for Persons with Disabilities. Controls were carried out in different stations, directly on the platforms, to ensure that all standards are respected.

Other tests were carried out on newly-installed systems and on modernised systems:
- the operation of the new fire detection system was tested both in the passenger compartment and in the toilets;
- the transmission of the alarm to train support personnel and the locomotive engineer;
- the new customer information system;
- the new window glazing allowing mobile phone signal to pass.
