Dear all,
please note the view from interlocking side:
<TrainDetectionElement>
It is an element on the track with a definitive position but without length. It
can be a axle counter detection point, a wheel sensor or an insulated rail
joint. It is NOT an entire track circuit.
<TrainDetectionElementSection>
First it seems to be a duplicate to the functional item <TvdSection> we have in
the interlocking part.
A TVD section is a part of a track (with length) used to detect whether there is
any rail vehicle in it. It is clearly delimited by detection elements or end of
tracks (buffer stop).
Best regards,
