Dear all,

if I want to export in railML 3.1 the schematic of a station that has several "real" bufferstops, and also some "fake" bufferstops representing the line borders (see image below), how can I export the fake ones?

/forum/index.php?t=getfile&id=48&private=0

I need to export them beacuse they define the borders of the tvdSection for the interlocking schema.

Any ideas?

Thanks in advance,
f.

Hi,

from interlocking point of view I think the tvdSection is delimited by the trainDetectionElement. A bufferstop would be
no active element for an interlocking.

I have added some detection points and names to your example:
tvdSection "R1" is delimited by "dp01" and "dp02"

tvdSection "R4" is delimited by "bs01" and "dp03"

The infrastructure limits shall be marked by border elements.

Dear Joerg,
thanks for the quick answer.
I get your point, but I have another question then: what kind of "trainDetectionElement" could a line border be?

From the 3.1 railML documentation the possible values are:

<xs:enumeration value="axleCounter"/>
<xs:enumeration value="axleCountingCircuit"/>
<xs:enumeration value="clearancePoint"/>
<xs:enumeration value="insulatedRailJoint"/>
<xs:enumeration value="trackCircuit"/>
<xs:enumeration value="virtualClearancePoint"/

Any suggestion?

Thanks again in advance,

f.

Dear Fabiana,

1) "border" element of type="rail3:Border" is a separate functionalInfrastructure element

2) a "trainDetectionElement" delimiting a tvdSection can be only of type "axleCounter" or "insulatedRailJoint". You may
consider "insulatedRailJoint" also for locations limiting an audio frequency track circuit without having a physical
insulation in the rails.

A "trackCircuit" would be already an equivalent to "tvdSection", i.e. not representing a spotLocation.
A "clearancePoint" or "virtualClearancePoint" is not really a mean to detect the presence of a train on the track -
explanation for use is missing.
For "axleCountingCircuit" I have no clue what it stands for, but it seems also not representing a spotLocation.
