Several colleagues have pointed out to me, dull knife in the drawer that I am, that 1086 hours is about 6 months work for a single person. The brings to my mind a disturbing implication.
Has FRA has not produced monthly analysis of PTC performance-- trains scheduled to operate with PTC engaged and operable; actual trains operated with PTC engaged and operable; runs completed by trains with PTC engaged and operable; number of PTC initiated enforcements as a percentage of runs completed with PTC engaged and operable; number of false enforcements as a percentage of runs completed, etc. etc. -- aggregating and processing the data by type of PTC system deployed (I-ETMS/ETMS, ITCS, ACSES II) rather than by railroad?
To date, has FRA produced no trend analysis reflecting the improvement or lack thereof, in PTC reliability, i.e. an increase in the number of PTC runs completed with PTC operable and engaged, by type rather than railroad?
Has FRA not produced a trend analysis of the reduction over time, if any, of PTC initiated enforcements, and the decline of false enforcements, by type rather than railroad?
Certainly such analysis would have to take note of new properties or new territories being brought into the RSD or PTC operation, as we might expect "more bumps" in the initial roll-outs.
If FRA has developed such analysis, that is precisely what I am requesting.
Thank you,
And if FRA hasn't produced that analysis? Then why not?
