Can i get to lga in nyc by train?

Yes, you can reach LaGuardia Airport (LGA) by train, but it requires a combination of train and bus or subway services. You can take a train to either Penn Station or Grand Central Terminal, and then transfer to a bus (like the Q70 SBS) that goes directly to LGA. Alternatively, you can take the subway to Astoria and then catch a bus to the airport.
