Travellers headed to Penn Station faced a rough commute after Monday's derailment of a New Jersey Transit train.

There's almost no room for error in the overcrowded Penn Station schedule, so all three rail services using the station are affected.

The MTA says 10 rush hour Long Island Rail Road (LIRR) trains are canceled for Wednesday morning, while 24 trains were either canceled or rerouted Tuesday evening.

Four more were being diverted to Jamaica, Queens, and one is being re-routed to Hunterspoint Avenue in Queens.

New Jersey Transit trains ran on a holiday schedule all day Tuesday.

NJ Transit buses, private carriers, PATH, and NY Waterway Ferries have been cross-honoring tickets.

Transit authorities say Amtrak crews are working around the clock to get the damaged track and switch up and running.

The repairs could take several days, but some commuters are staying hopeful.

Metro-North riders on the Port Jervis and Pascack Valley Lines are urged to stay on their trains until they reach Hoboken, where they can take the PATH into Manhattan. 

Amtrak will operate on a modified schedule between New York and Washington D.C.

Customers may see delays of up to 60 minutes during rush hours and 30 minutes or less during non-rush hours.

Five people suffered minor injuries Monday when a New Jersey Transit train from Trenton derailed as it pulled into Penn Station.

Crews are still working to repair the damage.

The derailment led to dozens of train cancellations, and delays that lasted into the evening rush.

This is the second train derailment at Penn Station in less than two weeks.

An Amtrak train clipped a New Jersey Transit train at low speed back on March 24.
