Digital Train Control System for Frankfurt’s Subway and Tram Systems
The authority for public transport in the city of Frankfurt, Verkehrsgesellschaft Frankfurt (VGF), will replace its conventional train control system previously used in the subway and tram sector with a new, modern and digital system. The “Digital Train Control System Frankfurt” (DTC) project is one of VGF’s most important projects for the future.
Systems such as the “Digital Train Control System Frankfurt” are referred to in the industry as “Communication Based Train Control” (CBTC). CBTC is a complex system of digital signals and messages that permanently exchange information between vehicles and track in real time. Various components on the track and in the vehicles make this radio-based, bidirectional data communication between train and infrastructure possible, in which track information is transmitted to the trains via radio system.
