Babylon station originally opened as a South Side Railroad of Long Island depot on October 28, 1867.From that point on the original SSRLI depot contained the name "Babylon & Fire Island" posted on one side.[6] It was razed in 1963 as part of the grade crossing elimination project that was taking place along the entire Babylon Branch during the post-war era.[8][9] In June 2010, the Long Island Rail Road broke ground on a new environmentally friendly train wash canopy, as at the time, the Mid-Suffolk Yard adjacent to the Ronkonkoma station had the only train wash on the east end.Additions include new canopies, escalators & elevators, and the replacement of bathrooms, stairs, platforms, and waiting rooms.
