Where Subway Service Improved in New York City

"Transit leaders say the subway is getting better as they work to overhaul the system, but riders are more likely to have felt the improvements on some lines than on others," reports Sergio Peçanha.

"Passengers of the E line saw their rides get faster by one minute and 14 seconds on average in May, compared with the same month last year. Riders of the L, J, Z and W lines, however, saw their average ride get a few seconds slower."

Peçanha is sharing the latest data from "additional train time" metric tracked by the Metropolitan Transportation Authority. To illustrate the findings described above, Peçanha presents a series of infographics.

The improvements are the result of hundreds of millions of dollars spent on repairs, "raising speed limits and fixing faulty signals." Subway officials also credit "changes in schedule, which the agency said allow trains to run more efficiently," for the improvements.
