Hello everybody,
since I'm new to RailML community I'll briefly introduce myself: I'm Fabiana Diotallevi from NEAT (www.neat.it), an Italian design and development company, with solid experience in creating HW&SW solutions for mission and safety critical applications.
At the moment we are developing a tool for drawing and visualizing fully equipped railway track plans, and for easily editing, checking and importing and/or exporting the relative objects properties in different formats (among which, of course, railML).
I have read the documentation regarding the Infrastructure and the Interlocking Scheme, and I have some doubts on how to link the trackCircuit xml representation between the Infrastructure and Interlocking Scheme.
Consider for example the situation depicted in the attached figure: my goal is to find the correct representation of the netElements, the tracks, the trainDetectionElements (Infrastructure Scheme) and the TvDSection (Interlocking Scheme) of this very unrealistic case study.
In the figure there are 6 trackcircuits, delimited by 5 joints. The trackcircuits (in the real world) are composed by the the following segments:
• TC01 = a
• TC02 = b+c+e
• TC03 = d
• TC04= f+h+i
• TC05 = g
• TC06 = l
According to what I understood reading the railML documentation, the 6 trackcircuits correspond the 6 TvdSections in the Interlocking Scheme, is this correct?
Another point I would like you to confirm me, is that, if I have only one operational point, in the Infrastructure scheme the netElement representation corresponds to the Track representation.
In particular, I would say that the netElements and tracks representation of this case study should be the following:
• trc01 = ne_01 = a+b
• trc02 = ne_02 = c+d
• trc03 = ne_03 = e+f
• trc04 = ne_04 = g+h
• trc05 = ne_05 = i+l
For what concerns the limiting joints , they should be represented in the following way as trainDetectionElements:
• J1 = tde01 => netElementRef="ne_a01"
• J2 = tde02 => netElementRef="ne_a02"
• J3 = tde03 => netElementRef="ne_a03"
• J4 = tde04 => netElementRef="ne_a04"
• J5 = tde05 => netElementRef="ne_a05"
Finally, for the TvdSection we should have:
• Tvd01 = TC01 -> DemarcatingTraindetector ="j1"
• Tvd02 = TC02-> DemarcatingTraindetector ="j1", "j2", "j3"
• Tvd03 = TC03-> DemarcatingTraindetector ="j2"
• Tvd04= TC04-> DemarcatingTraindetector ="j3","j4","j5"
• Tvd05 = TC05-> DemarcatingTraindetector ="j4"
• Tvd06 = TC06-> DemarcatingTraindetector ="j5"
Is all of this correct?
Thanks in advance for your feedback,
Fabiana
