Syosset has two high-level side platforms, each 12 cars long. The station is on a curve, necessitating a wider than normal gap between the platform and train. At places where train doors open, most of the gaps span ten inches or more; some gaps measure 15 inches. Black ice may cause commuters to fall into the gap. On January 30, 1996, in separate incidents, three commuters in a 90-minute period fell into the gap at the station due to icy platform conditions.
