Data Feeds

This section describes the numerous data feeds that acumen consumes.

POINTA CIF

A train service database (TSDB) is maintained within acumen; the TSDB is created from a full extract CIF file kept up to date by consumption of an incremental update which takes place each morning at 01:00.

Both the full CIF and incremental update CIF files are obtained via SFTP directly from Network Rail PPTE (Pre-production Test Environment).

As published by ITPS, the CIF contains limited train association data (AA records) however, prior to publication to PPTE for consumption, the CIF is parsed by a service known as POINTA. POINTA is a service which infers associations and enriches the CIF file, prior to publication.
