Thursday morning, all 11 branches of the Long Island Rail Road are back in service for the first time since the storm struck.
Also, Metro-North will expand bus service for the Port Jervis line, which is suspended indefinitely because of track damage and flooding that has been described as "catastrophic."
It could take months to fix.
The LIRR restored service between Ronkonkoma and Greenport just in time for Thursday's a.m. rush. That was the last of the lines to experience a service disruption.
Customers should monitor the MTA website, MTA.info, listen to the latest traffic reports and sign up for free E-Alerts for updates on service.
