Get ready for “Summer of Hell II.”

Amtrak on Tuesday announced a massive, multimillion-dollar repair project scheduled for this summer that will force changes on several commuter lines.

“Critical reconstruction” work will be performed on the Empire Tunnel, Spuyten Duyvil Bridge and Track 19 in New York Penn Station, Amtrak said.

As a result, Empire Service, Ethan Allen Express, Adirondack and Maple Leaf trains will be rerouted from New York Penn Station to Grand Central Terminal between May 26 and Sept. 4.

The Lake Shore Limited will only run between Boston and Chicago, with New York City and Hudson Valley travelers connecting from Empire Service trains at Albany-Rensselaer.

The repairs will cost between $45 million and $50 million.

“While the schedules have yet to be finalized, there will be fewer service impacts and schedule changes compared to Summer 2017,” Amtrak said, referring to the eight weeks of repairs that sparked a “Summer of Hell” at Penn Station.

The work on Track 19 will begin June 8 and last until July 20 and service will continue running on a modified schedule announced in January until the work is finished.

Specifically, Amtrak plans to replace the track in the Empire Tunnel, as well as replace cross ties, grade crossings and 8,000 feet of continuous rail between the tunnel and the Spuyten Duyvil Bridge.

On the bridge, Amtrak will be updating mechanical and electrical equipment that was corroded by Superstorm Sandy.

Three turnouts — which help train cars switch from one track to another — will be replaced along Track 19. Amtrak will also do a total replacement of the ballast and wood tie tracks.

Amtrak said it’s in the process of updating its schedule to reflect the changes in train service and that customers who’ve already reserved tickets will be “contacted and accommodated” on other scheduled services.
