2.5.2 Mounting position
The transponder should be mounted in such a way that it fulfils the specified
distances between the antenna and the transponder.
distances between the antenna and the transponder.
It is not possible to set the mounting distances and tolerances for the
transponder without taking any consideration to the mounting distance and
tolerance for the antenna on the vehicles. The co-ordination between tolerances
for onboard and wayside equipment must be stated in the initialising phase of an
ATP-application.

2.5.2.1 Vertical position
The recommended distance from the transponder mounting plane to the top of
the rail (E), is TBD + 20 mm. In the tolerance, reduction for the height of the rail
according to rail wear must be considered. That means the rail wear must be
within the tolerance.
