CIF Schedule Records

Overview

Schedule records are contained within the SCHEDULE data feed, and provide information about the possible schedules available for trains. For a given train service, there may be multiple schedules listed - the date of the train service and any short / very-short term plans will affect which schedule is current.

A schedule record comprises of a header containing a schedule UID, data about the schedule (including whether it is a train, bus or ship) and validity dates, and an ordered list of locations and times at which a particular service should arrive, depart or pass.

• Originating locations will always have a WTT departure time and optionally a public departure time
• Intermediate locations in a schedule will have a passing time if they are a mandatory timing point, or an arrival and departure time if the train carries out an activity at that location
• Terminating locations will always have a WTT arrival time and optionally a public arrival time, which may be some minutes later than the WTT time
• A location may have one or more activities associated with it - for example, U for locations where the train calls to pick up passengers (i.e. not available for alighting), D for locations where the train calls to set down passengers (i.e. not available for boarding).
• A location may have engineering, pathing or performance allowances

Record Format

A schedule comprises a BS (Basic Schedule) record. For actions other than 'delete', there will be a BX (Basic Schedule Extended) record, and a group comprising LO/LI/CR/LT records:

• Exactly one Location Origin (LO) record
• Zero or more Location Intermediate (LI) records
• Zero or more Change en Route (CR) records
• Exactly one Location Terminate (LT) record.

For BS records with a type of 'delete', this will be the only record, as schedules to be deleted are identified only by a truncated record.
