Dear Christian,
How <openEnd> and <macroscopicNode> elements present in 2.3 version can be modeled within railML3?
Generally speaking, what are the allowed values for trackBegin and trackEnd elements: are switches, crossings and bufferStops the only allowed values?

Thanks

BR

Fabrizio

<track> child elements <trackBegin> and <trackEnd> provide reference to
demarcating infrastructure elements. At microscopic level, a <track> may
reference <bufferStop>, <switch> or <crossing> elements as begin and
end. At the aggregated mesoscopic or macroscopic level a <track> may
reference <operationalPoint> or <border> elements. If you want to model
a station track without knowing exactly about the underlying microscopic
topology network, a possible solution may look like this:

<operationalPoint id="opp01">
</operationalPoint>
....
<track id="trc01" type="sidingTrack" length="320">
<trackBegin ref="opp01"/>
<trackEnd ref="opp01"/>
</track>

This solution is very close to the implementation in railML 2.3, see
"Best Practices" in [1].

But how about the "open end"? Does anybody have a brilliant idea on how
to model them in railML v3?
