The concourse at Hoboken Terminal reopened ahead of schedule on Sunday.
The temporary green wall that restricted access has come down, New Jersey Transit said. That will give riders more room to walk and easier access to track 7.
The concourse was scheduled to open in June. It has been closed since a Sept. 29 commuter train crash that killed one woman and injured 100 others.
Track 6 will open reopen for service, New Jersey Transit announced, leaving only one track closed.
