NJ Transit has resumed limited service on Monday in and out of New York's Penn Station after a derailed NJ Transit train impacted commuters' morning routines.

According to the NJ Transit website, limited service on the NEC and NJCL lines has been restored in and out of Penn Station, with estimated delays of at least 30 minutes. The RVL line is operating to and from Newark Penn Station (NPS).

The train, which was arriving from Trenton, was traveling at a slow speed when it derailed, causing a minor injury to one person, NJ Transit said.

The derailment comes just 1.5 weeks after an Amtrak Acela train derailed at Penn Station on March 24, causing some service disruptions. No injuries were reported. Both derailments occurred during rush hour, disrupting the morning commute for a busy route between New York and New Jersey.

NJ Transit is continuing to cross-honor tickets system wide, and MidTown Direct trains have been diverted to Hoboken.

Amtrak said on Twitter that it is monitoring the situation and will give updates.
