Most L.I.R.R. branches will have at least one Penn Station-bound train rerouted to Brooklyn or Queens. The good news is your L.I.R.R. ticket will get you onto the subway at no cost during the morning rush.

One important note: The route that takes you to work may not be the same one to take you home. Be sure to check the Metropolitan Transportation Authority’s website to find how your evening commute will change.

Babylon, Long Beach and West Hempstead Branches

Some Penn Station-bound trains will be rerouted to the Hunters Point Avenue station in Queens. From there, a 7 train will take you to Manhattan.

Babylon and Port Jefferson Branches

Some Penn Station-bound trains will end at Atlantic Terminal in Brooklyn. From there, you have a number of options to take you to work: The 2, 3, 4, 5, B, D, N, Q and R trains all go to Manhattan.

(Yes, the Babylon branch will have trains diverted to both Queens and Brooklyn. Be sure to check the schedule to see where yours will end up.)
