Mandatory braking in front of a steep gradient (de: Betriebsbremung)

Description

During the last railML conference (2013-03-06) in Berlin the discussion came to this aspect of the current speedChange implementation: If a goods train driver has not used its train brakes during a specified time (e.g. last hour) it should do an "operational braking" - not until standstill, but to check, if the brakes work properly.

This operation is indicated at the drivers timetable.

It seems, that the scenario is a very special German one, that is covered by the German operational rules. Brake tests are done very differently across other countries. It is not a general infrastructure specific issue, but more an operational one.

Therefore the implementation of mandatoryBraking in the element speedChange should be removed.

railML partners should use an "any"-Attribute as a short-term solution.

For re-inventing this feature it should be modeled in another way. There were no further proposals.

Proposed solution in railML 2.4

There is no need for a specific new attribute or element within . Interested users should for the beginning use an own extension in and come up with a proposal for railML 3.x implementation if required.

For clarification, the result of the discussion about mandatory braking points has been added as note on the railML wiki page about of the .
