The European Rail Traffic Management System (ERTMS) was introduced to establish a uniform railway management and control system on Europe's busiest lines. It revolves around the European Train Control System (ETCS). Most of Switzerland's standard-gauge network has been equipped with this system since 2018. The FOT's current ERTMS strategy is to continue optimising the ETCS and its associated systems, such as the railway mobile radio (GSM-R). This is aimed at further facilitating cross-border traffic.
