If the MTB is part of the emergency braking performance then it is subject to specific safety and reliability requirements with respect to its availability to be applied. In this situation the retardation rate can be included in the braked weight value/overall retardation of the vehicle. b) Brake application under low adhesion conditions or steep slopes: The MTB may be actuated at the driver’s discretion independently of the wheel/rail adhesion dependent brake.

qx = lateral clearance + The distance between the centre lines of the magnets shall be 1 510 mm for standard gauge (1 435 mm), see Annex C. When intended for use on different gauges the distance between the centre lines shall be adjusted accordingly. A bogie shall always comprise two magnets with pole shoes of identical construction. Appropriate devices (e. g. tie bars) shall be provided to maintain the pole shoes in a parallel position to each other. When the rail head is interrupted (switches, crossings), guidance of the magnet along the longitudinal axis of the rail head and its geometrical position, in relation to the vertical axis, shall be ensured in an optimum way to achieve a retardation rate that is as uniform as possible and to make sure that the MTB guiding elements in the running gear be subjected to the least possible mechanical load. The working MTB shall be capable of passing over switches and crossings (incorporating fixed crossings). A reference switch where the tangent of the crossing angle is tg . ≥ 0,034 is able to verify the capable function. 5.4 Rest position of the magnet above the rail surface The MTB when in its rest position with the vehicle in working order, with fully worn wheels and taking into account static deflection of the running gear shall: — remain within the space "b", as defined in EN 15273-1:2013, Figure C.4; — be 40 mm to 100 mm above the rail surface. It may be assumed that the stationary parts in the switch and crossing environment do not exceed a height of 80 mm above the rail surface. 5.5 Magnet elements 5.5.1 End pieces The end pieces of a magnet have several tasks: — they protect the magnet pole shoes transmitting the braking force from mechanical damage; — they assist the passage of the magnet over switches and crossings when the magnets are in working position, to reduce the risk of derailment; — they contribute to the overall retardation generated by the magnet.

To permit the use of wheel skates, it shall be possible to remove the magnets or their end pieces without damage. 5.7 Strength requirements The MTB (magnets, actuators, tie bar, brake reaction bracket – see Figure 1) should be designed so that: — no resonant vibrations are exerted on the bogie frame and the parts of the MTB; SIST EN 16207:2014

Key 1 magnet with segmented or rigid pole shoes 2 actuator 3 centring device to restrict lateral movement in the rest position 4 tie bar Figure 3 — Designations In its high suspension type the MTB is held in its rest position by spring force and is fastened to the running gear by means of centring devices. In this rest position the MTB is engaged with the bogie frame and is subject to a series of forces exerted on the latter, originating from elastic variations of the bogie frame. To permit a comparable assessment to be made, independently of the real design, a square horizontal level with a lateral length of about 1 000 mm is defined as a „reference surface“.
