A pro-Palestinian demonstration gathered inside Penn Station's Moynihan Train Hall in midtown Manhattan on Monday evening.
The group came from the Port Authority Bus Terminal, and earlier marched down 42nd Street from Grand Central Terminal where the MTA earlier warned commuters about travel restrictions.
Police could be seen barricading and blocking entrances to Penn Station around 5 p.m., including a NJ TRANSIT entrance on 7th Avenue, but the group appeared able to enter the building on 33rd Street.

In a social post on X, formerly Twitter, a Long Island Rail Road account said passengers should "expect possible access restrictions to/from Grand Central due to demonstrations in the area." A short time later, a follow-up post said there were restrictions in place.
The MTA recommended travelers allow extra travel time through Grand Central Monday afternoon.
Demonstrators could be seen in the main hall at Grand Central shortly after 3 p.m. Police closed some of the entrances to the terminal.
