A new study shows city straphangers' morning commute has been getting longer due to subway problems.

According to the study by the city's Independent Budget Office (IBO), there have been fewer trains running on time and more frequent gaps in between, with the most common cause for delays being overcrowding.

The IBO reports each year since 2012, riders on every train line on the morning commute lost more hours of their day to subway delays. 

It says for the 1.5 million morning commuters riding the subway from May 2012 to May 2017, there has been a 45 percent increase in lost hours when traveling to work on a typical weekday.

The study was named after the subway phrase, "We are being held momentarily." 
      
The data comes after Joe Lhota returned back to run the MTA.  He says his $836 million plan to fix the transit system is showing improvements in month-to-month data over the summer.
