The second minor train derailment at Penn Station in two weeks caused New Jersey Transit service to be suspended in and out of the Manhattan hub on Monday.

At least one person had minor injuries after the “slow speed derailment” at about 9 a.m. as a train pulled into Track 9 at Penn Station, said Nancy J. Snyder, a spokeswoman for New Jersey Transit. About 1,200 riders were on the train, which left Trenton at 7:31 a.m., she said.

Midtown Direct trains were being diverted to Hoboken, and cross honoring was in effect with New Jersey Transit bus, private carriers, New York Waterway and with PATH at the Newark, Hoboken and 33rd Street stations.
