On the rise for years, new MTA numbers show there has been some improvement when it comes to cutting the number of delays that plague the system.

Data reveals nearly 58,500 weekday delays in September.

That's close to 10,000 fewer delays than when subway service was at its worst in May and June.

The MTA says the dip in delays points to the impact of the "Subway Action Plan" that went into effect in July.  That's when crews began inspecting signals and subway cars more frequently, along with clearing garbage from the tracks.

Agency numbers show major signal problems and debris-related track fires are also down by more than 20%.

But weekday delays are still up by close to double what they were in 2012.
