Train service resumes at NYC's Penn Station

Trains are running again in and out of New York City's Penn Station, but not without a few delays.

Wednesday's slow morning commute came a day after two cars of a New Jersey-bound train derailed in a Hudson River tunnel near Penn Station. No one was injured.

The derailment forced authorities to shut down one of the two Hudson River rail tunnels between Manhattan and New Jersey but service was restored early Wednesday.

Some trains coming to the city from New Jersey experienced up to 60 minutes delays due to continued repair work on the damaged track. Amtrak says that work was finished at 8:15 a.m., and full service has been restored between Boston and Washington. Residual delays are possible.

Long Island Rail Road trains are running normally.
