  "heading": "Classes of Control-Command Systems",
  "text": "Within the Control-Command Subsystem two classes of train protection, radio communication, HABD and train detection systems are defined:\nClass A: The unified Control-Command system.\nClass B: Control-Command systems and applications existing before entry into force of the Directive 96/48/EC, limited to those described in Annex B.\nIn order to achieve Interoperability, the trains’ On-board Control-Command Assembly will provide:\nthe Class A radio and data communication interfaces to the infrastructure, in case of operation with Class A infrastructure,\nthe Class B radio and data communication interfaces to the infrastructure, in case of operation with Class B infrastructure. For signalling data, this can be achieved with the use of a Specific Transmission Module (STM) that allows a Class A On-board system to operate on lines fitted with Class B Track-side system using the Class B data. The interface between the Class A On-board system and STM’s is defined in this TSI.\nMember States have the responsibility to ensure that Class B systems are managed during their lifetime; in particular any changes to these specifications must not prejudice interoperability.",
