In September 2005 the Federal Office of Transport instructs the SBB to introduce the new European Train Control System (ETCS). Instead of relying on external visual signals, the Level 2 version of the ETCS transmits movement commands via a digital radio network to a screen in the driver's cab. The system continuously monitors the train's movements and the driver's reactions, allowing trains to travel at higher speeds and closer together. It is introduced on the Lötschberg and Gotthard base lines.

an hour can use the Gotthard Base Tunnel in each direction, thanks to the state-of-the-art communication technology of the ETCS (Level 2).
train drivers cannot see signals at this speed – they are radioed to the driver's cab.
