Metro-North Railroad reopened its New Haven Line service around 8 a.m. Wednesday morning after “extensive damage” from Tropical Storm Isaias forced it to shut down.

Officials said service between Stamford and Grand Central will resume on weekend schedule.

Riders “may experience delays up to 45 minutes and train cancellations due to repair efforts and power issues,” officials said in a post on Twitter Wednesday afternoon.

Officials also reported that New Canaan Branch service has been suspended from New Canaan to Stamford due to extensive damage to our infrastructure as a result of the storm and many road detours and closures which hindered busing efforts.

“Crews are working to make repairs and restore service,” they said.

The railroad announced early Wednesday morning that the New Haven Line service would be “suspended” as crews worked to clear debris from tracks around the state.

“We are clearing trees and repairing power and signal outages to restore service ASAP, we will provide that information as soon as it becomes available,” Metro-North said in its statement.

There is no timetable for the New Haven Line’s reopening.
