Hello.

Now we are using rollingstock scheme for the exchanging
among train management systems at switchyards and terminals.
(only for urban commuter passengers' cars)

We have some suggestions(requests) for the rollingstock
scheme depended on characteristic of our trains.

1. We have no engine cars. (like tram or metro in Europe.)
So we use "wagon" and "passenger" elements for all rollingstocks.
We would like to add 3 attributes of technical specifications
to the "passenger" element.
'maxTractEffort','resistFactor' and 'rotMassFactor'

2. And we have some services for 1 rollingstock. Now we have
1 attribute 'service' for 1 rollingstock, it is useful for
us if it is repeatable.

3. We hope "rs" element have a key index attribute like
'rsType' because all rollingstocks have their unique
ID numbers in our systems.

4. Our trains are composed fixed some rollingstocks, so
we manage them by unit of train compositions called
formations, not by unit of rollingstocks.
So we hope the elements for the formations. Now we
are planning the "formations" element which is at the
same level to "rollingstocks" element. Our draft
files are at
https://www.jrsi.co.jp/railml/trainFormationJ/
which are included over 1 to 3 items.
trainFormationJ.xsd.xml --- scheme difinition file
please get it and rename to trainFormation.xsd
trainFormationJ.xml --- example data file
trainFormationJ.txt --- an explanation file

Comments or questions are welcome.

Best regards from Tokyo

Hallo.

I am worked on the rolling stock scheme the last months incorporating
several new elements according suggestions. I hope to be able to publish
the scheme in a couple of days. Here some remarks on your suggestions:

'resistFactor' and 'rotMassFactor' has been added to element 'wagon', thus
it can be used for passenger and freight wagons. However, the
'maxTractEffort' is characteristic for motored cars only, therefore it is
not sensible to appear for trailor cars.

> 3. We hope "rs" element have a key index attribute like

Yes, the 'rs' element comprises a 'rsID' to have a unique identifier for
reference.

According your proposal I have enhanced to scheme:
- 'class' element (general data of vehicle) now optional
reference via 'rsID' attribute of 'rs' element
- two branches under 'railml': 'rollingstock' & 'formations'
'formations' contains all data related to a train as a set of 'rs'
elements
- 'trainResistance' element has been moved into 'formation' branch as it is
train related
- attribute 'tunnelFactor' has been moved from 'rs' to 'trainResistance'
- for all elements containing a 'math' element the 'valueTable' element was
added as alternative, i.e. both possibilities are optional
- consequent use of attribute type decimal for any floating point value
- attribute 'rotMass' at 'rs' deleted, but 'rotMassFactor' at 'wagon'
added
(rotating mass for non-motored axles)
- attribute 'resistFactor' at 'wagon' added
'rotMassFactor' and 'resistFactor' can now be used for motored cars
('propulsion') and non-motored cars ('wagon').
