Metro says its rail system is changing into extra dependable and bettering after years of decline, in response to paperwork introduced to the company’s Board of Administrators on Could 10. Metro hopes to make use of these improved reliability numbers to indicate misplaced riders that the system is getting higher and so they can return.

Metrorail reveals efficiency enhancements, however nonetheless removed from good
Metro’s MyTripTime metric, which debuted in Fiscal 12 months 2016, tracks how lengthy every particular person journey within the system ought to take. It components in strolling time from the fare gates to the platform, the utmost anticipated wait time for a practice, most switch waits, and the precise journey time.
The company says that 87% of journeys have been on time to date within the present fiscal yr to this point (2018). Solely 67% of journeys had been on time final yr when vital parts of the system had been shut down for SafeTrack, and 74% of journeys had been on time the yr earlier than that in FY 2016.
Metro’s practice on-time efficiency metric, which tracks how evenly spaced trains stay plus or minus two minutes, says the company has averaged 90% to date in FY 2018. Metro doesn’t report on-time efficiency evaluating practice station arrivals to the company’s printed schedules.
Railcar information launched by the company say that 559 offloads occurred within the first 9 months of the fiscal yr, in comparison with 883 and 1,298 in FY 2017 and FY 2016 to this point, respectively. Fewer Metrorail trains run this yr after a 25% service minimize carried out July 2017 precipitated trains to run solely each eight minutes as an alternative of each six.
The company attributes extra dependable trains to the continued acceptance of recent 7000-series trains and having been in a position to retire the 1000- and 4000-series automobiles. The 4000-series railcars have usually been the worst-performers within the Metrorail fleet, and the 7000-series automobiles have develop into the brand new ‘star’ performer, working extra reliably on common than even the 6000s.

Two measures Metro makes use of to trace how dependable railcars are Imply Distance Between Delays (MDBD) and Imply Distance Between Failure (MDBF). The later usually is a extra “true” measure of reliability of the railcar, whereas the MDBD metric measures reliability that may range based mostly on operator and rail visitors controller expertise.
Railcar MDBD has been on the rise over the past three fiscal years. It averaged 55,000 miles in FY 2016 whereas reliability elevated to 73,000 miles in FY 2017, and is to date averaging 86,800 miles within the first 9 months of FY 2018. Metro’s objective is 85,000 miles.
Railcar MDBF equally elevated over the previous three years from 5,000 to five,900 and now 9,700 miles in FY 2016, 2017, and 2018 respectively. The 7000-series automobiles have averaged 17,300 miles MDBF to date in FY 2018 and leads the fleet. The following-highest dependable sequence is the 2000s, averaging 10,400 miles MDBF this yr.
Observe issues have begun to return down
The variety of instances trains ran previous a purple observe sign decreased from 14 in 2017 in comparison with seven to date in 2018. There have been eight reported purple sign violations in 2016. The company attributes the decline to upgrading indicators from common bulbs to LEDs so that they’re simpler to see, improved upkeep, and improved communications.
Fires on the tracks have barely declined from 66 in each FY to this point 2016 and 2017 to 61 to date in 2018. Probably the most fires this yr had been attributed to arcing (27) adopted carefully by “non-electrical” fires (26). 5 of the 61 fires this fiscal yr have been cable fires, just like these which contributed to a system-wide Metrorail shutdown again in 2016 and the dying of a passenger in 2015.
As well as, 11% of the system’s tracks have been below pace restrictions that restrict how briskly trains can run. Pace restrictions are positioned on tracks when inspectors determine defects, and restrictions can sluggish trains right down to ‘medium’ speeds round 35 mph, sluggish speeds under 15 mph, or utterly halt practice visitors in an space.
Metro’s objective is to have under 2.2% of tracks below pace restrictions when the metric is measured at 9 am on the primary Wednesday of each month. A pace restriction on the Pink and Orange/Silver/Blue traces limiting trains to 35 mph might be lifted as quickly as this summer time, in response to company paperwork. The restriction was carried out resulting from a Federal Transit Administration directive instructing the company to scale back the facility draw of its trains.
Metro’s tracks had been in dangerous sufficient form in 2015 that an empty Orange Line practice derailed between Federal Triangle and Smithsonian stations resulting from tracks that had been too vast. Metro staff discovered the difficulty a month earlier, however didn’t act on the data and it went unaddressed. Inspectors had been ordered to judge each different curve within the Metrorail system afterwards to search out different crucial points.
