Characterizing Data / Charakterisierung der Daten

This section serves to specify the required data regarding certain aspects.

How often do the data change (update)?

• yearly for VLTP planning of frame contracts
• yearly for LTP planning the regular timetable
• regular changes for STP planning, e.g. for engineering infrastructure works, special event trains
• daily for VSTP planning, e.g. strike, ad hoc freight trains

How big are the data fragments to be exchanged (complexity)?

• Typically one train per order
• Maximum complexity is full timetable

Which views are represented by the data (focus)?

• Could be any of VLTP, LTP, STP, VSTP
• Covers the full train information, but for certain time periods

Which specific TT data do you expect to receive/send (elements)?

• Workflow information
  • Not part of the timetable data
• Trains
  • Identifier, e.g. <train>.trainNumber
• Operating periods
• Train run <trainPart>
  • Earliest arrival
  • Latest arrival
  • Earliest departure
  • Latest departure
  • Minimum stop time
  • Stop type, stop description
  • Commercial connections
• Infrastructure <ocpTT>
  • Ordered stops
• Rolling stock <formationTT>
  • Loco types
  • Weight
  • Length
  • Maximum speed
  • Infrastructure restrictions

Which specific IS data do you expect to receive/send (elements)?

As a minimum the <ocpTT> elements with commercially relevant stops have to be listed in a <trainPart>. The <infrastructure> has to provide the related {[tag|is|ocp}} elements.

Which specific RS data do you expect to receive/send (elements)?

There is no mandatory requirement for detailed <vehicle> information. The loco types may be used to identify performance characteristics and infrastructure restrictions by the Infrastructure Manager.
