An analysis by a commuter advocacy group has found that the Nos. 2 and 5 subway lines had the most number of incidents that led to delays in 2011.
The NYPIRG Straphangers Campaign says those lines each accounted for 8 percent of "MTA alerts'' issued that year.
The G line had the fewest number with only 45 service alerts.
The MTA issues the alerts via email and text messages to warn riders of possible delays "expected to last 8 to 10 minutes or more.''
The Straphangers Campaign didn't include in its analysis delays that were out of the MTA's control, such as police activity or sick passengers.
