A pedestrian on the railroad tracks was hit and killed by a LIRR train just west of the Garden City station Monday afternoon, the commuter rail said.

Service on the Hempstead branch was suspended about 1:03 p.m. in both directions between Jamaica and Hempstead for more than an hour after the fatality, said Meredith Daniels, a spokeswoman for the Long Island Rail Road.
