Track Info • Tracks also have additional properties, such as: • Category • Use • Year Built • Condition Information
Track Location Referencing • Each track has a station location referencing system applied. • RAILER uses a “track-feet” stationing system. • Tracks generally begin at station 0+00 • Location referencing system serves to locate inventory features and defects along the length of track.
Track Segments • Because some tracks can be very long, Segments can divide Tracks into smaller management units • Inspection, condition assessment, and maintenance planning is performed individually on each Segment • Tracks are usually segmented at Point-of-Switch locations • Segments have a begin and end location, and a length.
