# Commission Decision of 14 November 2012 concerning the technical specification for interoperability relating to the ‘operation and traffic management’ subsystem of the rail system in the European Union and amending Decision 2007/756/EC (notified under document C(2012) 8075) (Text with EEA relevance) (2012/757/EU), Division 4.2.2.6.2: Braking performance and maximum speed allowed

Extent: E+W+S+N.I.

(1) The infrastructure manager shall provide the railway undertaking with all relevant line characteristics for each route:
signalling distances (warning, stopping) containing their inherent safety margins,
gradients,
maximum permitted speeds, and
conditions of use of braking systems possibly affecting the infrastructure such as magnetic, regenerative and eddy-current brake.
(2) Additionally, the infrastructure manager may provide the following information:
(i) for trains able to run at a maximum speed higher than 200 km/h, deceleration profile and equivalent response time on level track;
(ii) for trainsets or for fixed train compositions, unable to run at a maximum speed higher than 200 km/h, deceleration (as above in (i)) or brake weight percentage;
(iii) for other trains (variable compositions of trains unable to run at a maximum speed higher than 200 km/h): brake weight percentage.
If the infrastructure manager provides the abovementioned information, it shall be made available to all RUs who intend to operate trains on its network. The braking tables already in use and accepted for the existing lines at the date of entry into force of the present regulation shall also be made available.
(3) The railway undertaking shall, in the planning stage, determine the braking capability of the train and corresponding maximum speed taking into account:
the relevant line characteristics as expressed in point (1) above or, if available, the information provided by the infrastructure manager in accordance to point (2) above. If the infrastructure manager has provided the information of point (2), the railway undertaking has to express the braking capability by using the same information, and
the rolling-stock-related margins derived from reliability and availability of the braking system.
Furthermore, the railway undertaking shall ensure that during operation each train achieves at least the necessary braking performance. The railway undertaking shall set up and implement corresponding rules and shall manage them within its safety management system.
In particular the railway undertaking has to set up rules to be used if a train does not reach the necessary braking performance during operation. In this case, the railway undertaking must immediately inform the infrastructure manager. The infrastructure manager may take appropriate measures to reduce the impact on the overall traffic on its network.
