CIF File Format
The Common Interface File (CIF) format is the industry standard for transfer of schedules electronically from Network Rail's Integrated Train Planning System (ITPS) to downstream operational and information systems.
The CIF file is a text file containing one record per row. Each record has a fixed length of 80 characters. The first two characters of a row identify the Record Type.
Record Types
- HD - Header record
- TI - TIPLOC Insert record
- TA - TIPLOC Amend record
- TD - TIPLOC Delete record
- AA - Association record
- BS - Basic schedule record
- BX - Basic schedule extra details record
- TN - Train specific note (unused)
- LO - Origin location record
- LI - Intermediate location record
- CR - Change en Route
- LT - Terminating location record
- LN - Location specific note (unused)
- ZZ - Trailer record (End of File)
The CIF End User Specification is also available from ATOC's website, which details the format of the CIF file and the fields within.
