Grand Central Terminal concourse. Exits and entrances are located at the center, west and east ends of the platform. There is an ADA-accessible elevator toward the west end. A newsstand/snack shop is located on the platform towards the east end. Two sections of the old Steinway Tunnel loop remain intact and are accessible to MTA personnel via the southbound track approximately beyond the station. The third is between the tracks and is a pump room. Parts of the loop were converted into CBTC circuit breaker rooms. The light and signage fixture that runs along the length of the platform is an art installation, entitled V-Beam, designed by Christopher Sproat. Image gallery IRT Third Avenue Line transfers For over a decade, free transfers were provided between the subway station and 42nd Street on the elevated IRT Third Avenue Line. This started on June 14, 1942, the day after the IRT Second Avenue Line, which provided access to Queensboro Plaza and the IRT Flushing Line, was closed. The Third Avenue Line closed on May 12, 1955, rendering the transfer obsolete.
