Division Essential requirement 2.4.1 Section 3:

‘The braking techniques and the stresses exerted must be compatible with the design of the tracks, engineering structures and signalling systems’.

For the present TSI, this requirement is dealt with by two basic parameters.

• the braking performances defined in Section 4.1.5,

• the maximum longitudinal force, defined in Section 4.1.1c, to be applied to the track without exceeding the maximum acceptable longitudinal force on the infrastructure.

Furthermore, the particular case of brake systems independent of wheel rail adhesion that use electromagnetic effects in the rail (eddy current brakes) rather than wheel/rail adhesion is tackled separately in Section 4.2.15 in order to evaluate the consequences of thermal effects in the rails.
