AAR Billing Code

AAR Billing Code: Unique for each owner. First position is zero for railroads, and non-zero for non-railroads. Next four positions are standard AAR 260 billing codes for railroads and unique substitutes for non-railroads.

Site ID

Site ID. Unique site ID for each owner.

Event Start Date

Event Start Date (YYMMDD)

Event Start Time

Event Start Time (HHMM) (local time)

Event Stop Time

Event Stop Time (HHMM)

Time Zone

Time Zone, hours offset from GMT (##.#, decimal assumed) 5=Eastern 6=Central 7=Mountain 8=Pacific

Daylight Savings Time Indicator

Daylight Savings Time Indicator (Y/N) Y=Daylight Savings time is in effect. N=Daylight Savings time is not in effect.

Data Format Version Number

Data Format Version Number (#.## with . assumed) First digit = Major change (May not be backwards compatible.) Second digit = Major enhancement (Is backwards compatible.) Third Digit = Processing upgrade.

Train Sequence Number

Train Sequence Number. A unique number that is incremented after each train is recorded. Range: 1-9999. Number wraps back to 1 after sequence 9999. Zero is an invalid train sequence number.

Locomotive Conversion Status

Locomotive Conversion Status, Consist Confidence Level G= Good (No signifcant problems) A= At least one questionable axle pattern was found D= Excessive disqualifiers (inconsistencies between tag and axle pattern) M= Multiple inconsistencies (both A and D) ?= Other

Railcar Conversion Status

Railcar Conversion Status, Consist Confidence Level G= Good (No signifcant problems) A= At least one questionable axle pattern was found D= Excessive disqualifiers (inconsistencies between tag and axle pattern) M= Multiple inconsistencies (both A and D) ?= Other

Direction of Travel

Direction of Travel Valid Values: N, S, E, W

Switch/Direction Indicator

Switch/Direction Indicator. (0-9) Owner-defined. Indicates the current position of local track switches (as reported by external switch point controllers or similar devices). This allows the host to identify the route the train is traveling (when more than one route exists).

Units of Measure

Units of Measure. English or metric units (E/M) for the entire report.

Maximum Speed

Maximum Speed (mph or kph)

Minimum Speed

Minimum Speed (mph or kph)

Average Speed

Average Speed (mph or kph)

Movement Status

Movement Status. Type of train movement. A= Through movement, over 5mph B= Through movement, under 5mph C= Through movement, stop and go D= Through movement, switching (direction changes detected) E= Simulation (software generated train) F= Reverse exit (pull by) R= Arrival Listing ?=Other

Termination Status

Termination Status. Indicates completion state of the train. N= Normal T= Time-out (Train did not move for a specified period of time.) Partial train will be reported. When train resumes movement, the train will be reported again with the new cars appended (same sequence and start time/date as original train). See appended trainsmission type below.

Transmission Type

Transmission Type R= Retransmission S= Summary F= First transmission A= Appended. Reported train replaces previous train fragment. Previous train was terminated by time-out. (See Termination Status aboe.)

Adjacent Track Occupied

Adjacent Track Occupied (Y/N) Y= Train was reported on adjacent track during the train. N= No activity on adjacent track.

Train Length

Train Length. Total distance from end to end (in feet or decimeters).

Equipment Status Code

Equipment Status Code. Reflects any abnormal site activity that occurred during or prior to the reported train. Details of reported event can be found in the maintenance report. A= Antenna warning. System is reading an unexpectedly low number of tags on at least one antenna. B= Antenna fatal. At least one antenna is no longer reading tags. C= Communication error with external components. E= Intertrack communication warning. Problem was detected, but not recovered. F= Intertrack communication fatal. Cannot communicate with external processor. G= Good. No problems detected. H= Power supply warning. Battery charger temporarily lost power. I= Power supply fatal. Battery charger lost power. K= Software setup failure. Software has detected an inaccurately set parameter. M= Multiple (More than one problem). P= Presence circuit warning. Problem was detected, but recovered. Q= Presence circuit fatal. Presence ciruit is no longer functional. R= Reader/RF warning. Problem was detected, but recovered. S= Reader/RF fatal. At least one reader is no longer functional. T= Wheel transudcer warning. Problem was detected, but recovered. U= Wheel transducer fatal. Transducer is no longer functional. V= No wheel transducer input. W= External detector trigger. IO device (such as a hut door switch or thermocouple) went active. W= External processor communications warning. Problem was detected with external processor (such as a scale or defect detector), but recovered. Y= External processor communications fatal. (External processor unit is no longer functional.) Z= Security. Excessive number of failed user logon attempts. ?= Other
