on the Lexington Avenue Line
Monday, September 9, 2013
For the third time this year, MTA New York City Transit’s highly-successful FASTRACK program came to the only subway line on the East Side of Manhattan. This was the first of four weeknights of our intensive maintenance and repair effort on the Lexington Avenue Line between Grand Central-42 St and 125 St. Local service on the four-mile long line segment was shut down from 10 p.m. until 5 a.m., and will be suspended for the next three nights through early Friday, September 13. During the closure, and service runs express in both directions between Grand Central-42 St and 125 St and service ends early.
Stopping all local train service on a subway segment, on four consecutive nights for seven continuous hours, gives maintenance crews the chance to perform many tasks on or near the tracks without having to stop work every few minutes while a train moves through the area. The section of the Lexington Avenue Line between the 51 St station and the 96 St station is bi-level. Local trains are on the upper level and express trains are on the lower level. This track arrangement allows maintenance crews to work on the lower level while trains are running on the express tracks above.
With no trains running along the local tracks between Grand Central-42 St and 125 St of the 95-year old Lexington Avenue Line, hundreds of maintenance workers were able to inspect signals and switches, repair and replace track rails and cross ties, clean track floors, perform elevator and escalator repair work, repair water damage, clear drains, and clean stations. Maintenance crews were also able to clear the track-bed of debris and paint areas that are not reachable during normal train operation. In addition to high-intensity station cleaning, work crews were able to clean lighting fixtures, change bulbs, and repair platform edges providing a visible improvement to the station environment.
Achievement by the Numbers
Major accomplishments from last night’s maintenance blitz include servicing six signals, testing seven signals, installing nine track tie blocks, and 191 track tie plates. Keeping the subway’s physical structure in good condition and clearing the track of debris is critical to service reliability as workers scraped 7,485 linear feet of track, removed 2,440 bags (30,300 pounds) of scrap and debris and cleaned 600 feet of track drain.
Work teams also repaired or replaced 30 feet of handrail, sealed ten leaks, repaired damaged concrete and inspected 8,020 linear feet of subway structure. With a goal of eliminating defects to the direct current power supply, crews corrected 125 third rail defects, scraped and cleaned 4,700 linear feet of track bed under and around the third rail.
With an eye on customer and employee safety as well as having an aesthetically-pleasing station environment, workers replaced 90 tunnel light bulbs, 11 station light bulbs, repaired or replaced 15 square feet of floor tile and repair 85 linear feet of rubbing board, the fiberglass extension attached to the platform edge. In addition, workers scraped 2,200 square feet of paintable surface, primed 900 square feet and painted eight K-A rails and 16 stairway copings. K-A rail is the street level railing, usually painted green, that surrounds the station entrance/exit stairway and stairway coping is the concrete base below the K-A rail. Stairway coping is usually painted black.
The FASTRACK project environment, introduced in 2012, experiences a significantly lower accident rate by participating employees. During FASTRACK events last year, the Lost Time Accident (LTA) rate per 100 Employees was 1.38 versus a rate of 2.42 during all other operations. An LTA is a job-related incident that results in the inability of an employee to perform their duties for at least one working day beyond the day of the incident.
How this Impacts Service
Reliable service - service you can depend on to get you to where you need to go when you need to get there - requires regularly scheduled maintenance to the critical components you never see. FASTRACK is having a positive impact on service reliability as train delays on subway lines that have undergone FASTRACK maintenance have dropped 4.4% and track fires have declined by 50%. FASTRACK is improving employee safety and service reliability.
