Explanation of Delays during Wednesday's AM Rush, Sept. 11, 2013
Just before 7 AM on September 11, a track condition involving a switch was detected east of Queens Village on one of two Main Line tracks. This section of track was taken out of service as track workers were dispatched to assess the problem. Without use of one of the two tracks in this area, three westbound morning rush trains had to be canceled and other westbound trains experienced initial delays of 5-10 minutes.
About an hour later, a second switch – this one located between Mineola and Merillon Avenue – developed an unrelated problem, that adversely affected our ability to route trains from one track to another. The combination of the two separate switch problems increased the delay range up to 20 minutes for both east and westbound trains on the Port Jefferson, Ronkonkoma and Oyster Bay branches. Additionally, customers on three westbound trains affected by the second switch problem experienced lengthier delays when these trains had to make reverse moves to East Williston in order to switch to an alternate track.
With only a single track in service between Mineola and Queens Village, AM peak delays eventually increased up to 60 minutes. This loss of capacity required the cancellation of an additional westbound train and two eastbound trains. To accommodate customers affected by the cancellations, stops were added to other trains.
In all, four westbound AM peak trains were canceled, and a total of 24 westbound trains were delayed -- a few in excess of 60 minutes.
We apologize for the inconvenience our customers experienced during the morning rush. Wide temperature swings, as we recently experienced, can sometimes affect our track.
One of the two switch problems was corrected at 8:52 AM. Repair work is continuing on the switching point east of Queens Village, and our goal is to have these repairs completed in time for the evening rush hour. We advise customers to check service status on our website at www.mta.info for updates on the evening rush.
