There are some lines equipped with PZB and additional systems like LZB
or even ETCS.
How do you define multiple active train protection systems on a track?
<!-- PZB -->
<rail:trainProtectionChange id="tpc0" pos="0"
monitoring="intermittent" medium="inductive"/>
<!-- LZB -->
<rail:trainProtectionChange id="tpc1" pos="500"
monitoring="continuous" medium="cable"/>
Normally, the new *Change entry stops the previous similar entry.
That means, from pos=500 upwards there is _only_ LZB, no PZB.
How do you define this issue?
Any comments would be appreciated.
Kind regards,
Susanne

Dear all,
more than eight years ago we took notice of the problem that we cannot
model overlapping / multiple train protection systems along a track:

With upcoming railML 3.x, we finally can solve this problem: Each
<trainProtectionElement> instance has its own (linear) location and
these locations may overlap. So, if you want to define a track being
equipped with PZB and LZB (see example above), just define two
<trainProtectionElement> instances with overlapping locations.
Consequently, Trac ticket #80 [1] can finally be closed.
