The Swiss railways sends all information about delays and obstructions in the rail network direct to Viasuisse. There is even close co-operation with the large Swiss cities. Especially in a case of disruption it is important that the passengers should be informed as quickly as possible via as many channels as possible. In addition to the SBB information channels, Viasuisse helps with the 163 number and other output channels to supply travellers with up-to-date rail information. Since 1st November 2007 Viasuisse has also been operating the phone number 166 for SBB. This number can be used to obtain comprehensive information about rail travel.
