The MTA is moving forward with a long-term plan to bring Metro-North to Penn Station.
The agency is conducting an environmental study of how best to provide direct train service from its Hudson and New Haven lines to Penn Station.
The proposal includes daily Hudson Line service using Amtrak's Empire Connection with two new stations near West 125th and the Upper West Side.
Daily New Haven line service via the Hell Gate line would also undergo some changes including three new stations in Co-op City, Parkchester and Hunts Point.
While the plan is still in the early stages, the environmental assessment is expected to be complete by 2011.
