  "text": "To conform Directive 96/48/EC, and finally move towards a unified system, interoperable trainsets shall be compatible with the ERTMS system (Commission Decision 2001/260/EC). Compatibility with existing systems will be achieved using adaptive modules installed on the trainsets. In practical terms it would be impossible to install all the modules required on board a train set. The choice of modules shall be based on the routes for which the trainset is intended.\nThe interface characteristics between the rolling stock and the control command subsystem are included in Section 4.2.1.2 of the TSI for that subsystem, and are notably:\nthe minimum braking characteristics for the train covered in Section 4.1.5 of the present document,\ncompatibility between the ground-based train detection systems and the rolling stock, dealt with Section 4.1.9.1 of the present document,\ncompatibility between the detectors fixed under vehicles and the dynamic clearances of those vehicles,\nthe environmental conditions for the on-board equipment are dealt with in Section 4.3.12 of the present document,\nelectromagnetic compatibility with on-board control command equipment are dealt with in Section 4.1.9.4 of the present document,\ntrain data concerning braking, train integrity and train length,\nelectromagnetic compatibility with the ground-based systems covered in Section 4.1.9.3 of the present document.\nIn addition, the following functions are directly linked with parameters defined by the control-command subsystem.\noperation in degraded mode conditions\nmonitoring to ensure that the train speed is at all times less than or at most equal to the maximum permitted speed in the operating environment.\nInformation about the characteristics of these interfaces is given in Tables 5.1 A, 5.1 B and 6.1 in the control-command TSI. In addition, reference to European standards and specifications to be used as part of the assessment procedure for conformity are indicated, for each characteristic, in Annex A to the control-command TSI.",
