If you think you've been losing time because of subway delays, it's not your imagination.

According to the MTA, there were more than 58,000 delays in September. That's up nearly 4.5 percent from the nearly 56,000 the same time last year.

The agency says overcrowding is to blame for more than 40 percent of the weekday delays, and the MTA says track equipment and planned shutdowns caused nearly 30 percent of the weekend delays.

Depite this, subway ridership is still lower than last year.

To help keep things moving, the MTA is adding more roun-dtrip trains to several lines next June, including the 2, 3, 7, N/W, and Q.
