Control system for mountain railway

The Matterhorn Gotthard Bahn (MGBahn) railway carries over eight million passengers a year, making it one of Switzerland’s largest transit companies. The 144 km long rail network climbs a total altitude difference of more than 2000 m. To ensure efficient operation of the network, MGBahn has replaced the existing control system used for the traction power supply complete with network infrastructure, and opted to use a modern Ruggedcom solution from Siemens instead. The redundant system ensures reliable operation even in the event of a failure, enables convenient remote maintenance, and provides simple traction power supply control and monitoring over the entire rail network. The MGBahn runs from the Canton of Graubünden up to Zermatt below the Matterhorn. As the previous network structure used to be relatively complex and fault-prone, the operators took the decision to modernise the entire system. The solution is based on the Ruggedcom RX1500 Layer 3 switch. The smart multi-service network component combines the functions of switch, router and firewall with WAN connectivity.
