Sources for the NAR DataFor this presentation, the sole source for incidents is PHMSA’s 5800.1-based data
Canadian Class 1s also are voluntarily providing data on incidents in Canada, but we haven’t included that for 2018 yetRailroads are voluntarily adding BOE Cause Codes to their 5800.1 reportsMore precision than PHMSA Cause Codes

Further Notes on NAR DataSome gaps
Cause Codes sometimes missingCanadian short line incidents (and mainlines for 2018 at the moment)Did not attempt to include Mexican incidents
2017-2018 data do include US short line incidents, while previous years’ presentations lacked many of those – there are some notations on the trend graphs for comparability with previous yearsThe graphs shown here are preliminary because there has not been a full review of the various counts

Further Notes on NAR Data2018 9-month dataset required clean-up
One major carrier shows only 3 NARsOn the other hand, 44 records show N/A as the carrierCause codes entered with variable formatThe 44 N/As prevent a good understanding of how many records are from short lines
182 out of 263 (69%) have BOE Cause Codes assigned in the proper fieldMany of these have the codes on 5800, but not in database
