Amtrak may reroute some of its trains to Grand Central Terminal while it does repairs to Penn Station this summer, sources said Wednesday.

Amtrak officials have floated the idea in some meetings, the sources said.

“It is definitely a possibility,” said the source.

The move would give more track space to Long Island Rail Road and New Jersey Transit when the repairs are done this summer. Only about 10 percent of the trains that currently use Penn Station are Amtrak.

State Assembly members John McDonald and Patricia Fahy and Senator Neil Breslin sent a letter to Amtrak head Wick Moorman last week asking him to consider the idea.

“In the interest of being solution oriented, we would suggest exploring the feasibility of re-routing trains to Grand Central Station in the interim, especially in light of the fact that 20 years ago most trains were routed to Grand Central rather than Penn Station,” they wrote.

Amtrak officials would only say on Wednesday that they are “reviewing all options.” MTA and NJ Transit spokespeople both said they are still working out the details with the company.

It’s been a series of mishaps at Penn Station in recent months, with two derailments in the last two months alone. One of the derailments led to a week of hellish delays, disrupting the commutes of hundreds of thousands of riders, as Amtrak struggled to make repairs.

A week ago, signal problems in an East River tunnel caused several LIRR lines to be canceled and delayed just before the start of rush hour.
