Dear all,
we were recently discussing the different types of OCP in our railML 3.x
Schematic Track Plan use case working group. Therefore, I would like to
come back to this forum post opened by Torben Brand from
Jernbanedirektoratet:
>>> The attribute @operationalType is extended with the value
>>> "siding". In Norway a "siding" is an additional track on the
>>> path (section of line between stations). It is not a station
>>> according to Norwegian definition as it does not have a

>>> blocked during the operation of entering and leaving the
>>> siding. PS. There is a trackType under track with value
>>> "sidingTrack" This is described in the Wiki as: "This is a
>>> siding"

In order to complete the modelling, I suggest to follow Torben's
proposal and add the enumeration value "siding" for attribute
<ocp><propOperational>@operationalType.
If you agree, we may bring this as last minute change into railML 2.4.
Best regards
