FROM THE MAILBAG:

Dear Gridlock Sam,

Is it true that on Metro-North from Connecticut, you'll be able to get to Secaucus, N.J., directly? How is this possible? I thought the train has to come through Grand Central.Jets Fan, New Haven

Dear Jets Fan,

There's a first time for everything, and Sunday marks the first time that a Metro-North train crew will come into Penn Station. Here's the scoop: Three trains on the New Haven Line will travel straight to Secaucus through Penn Station for all 1 p.m. Jets and Giants games, departing from New Haven at 8:05 a.m., 9:05 a.m. and 9:50 a.m. and postgame from Secaucus at 4:28 p.m., 5:28 p.m. and 6:28 p.m. At New Rochelle, the westbound Metro-North train will divert onto tracks operated by Amtrak, leading into Penn Station before proceeding to Secaucus. Here, fans can transfer to a Meadowlands-bound train for the 10-minute ride right to the stadium's front door. Therefore, these direct trains will not stop at Grand Central Terminal.
