NEWARK, N.J. — Statistics compiled by NJ TRANSIT found that the train, bus and light rail fleet are traveling fewer miles than just two years ago before breaking down, resulting in delays for commuters and snarled traffic when buses are disabled, NJ Advance Media reports.

NJ TRANSIT’s bus fleet traveled 11,668 miles between breakdowns so far this year, a decline from 12,325 miles in 2015 and from 12,525 miles in 2014. Meanwhile, trains hit a high of 120,591 miles between breakdowns in October 2012. That number slid to 103,813 miles in October 2013 and further to 87,750 in October 2014. The fleet saw some improvement, finishing 2015 with 89,655 miles traveled between failures, according NJ TRANSIT’s statistics.

Reliability is measured by mean distance between failures, which is the average mileage that NJ TRANSIT's rail and bus fleets travel before breaking down. The more miles traveled indicates that the fleet is more reliable. For the full story, click here.
