offices open either part-time or full-time, whereas others do not have open ones. Additionally, some stations that lack station houses used to have them; these station houses were razed. Station house designs The LIRR has an amalgam of different station house designs across its system. Many station houses built during the same time period (e.g., Mineola and Manhasset; 1920s), or as part of the same project (e.g., Central Islip and Deer Park; 1987 Hicksville–Ronkonkoma electrification project), share similar or identical designs. Platform lengths Platform lengths across the system vary from anywhere between train cars (only found at a handful of stations in diesel territory) to 14 cars; most stations in the system feature platforms long enough for 10-12 railcars (C3, M3, M7, or M9), each of which are about long. Below are a sample of various stations with different platform lengths throughout the system: Glen Street, located on the Oyster Bay Branch, has two side platforms, each -cars-long. Pinelawn, located on the Ronkonkoma Branch, has two side platforms, each 2-cars-long. Westwood, located on the West Hempstead Branch, has one side platform, which is 4-cars-long. Hampton Bays, located on the Montauk Branch, has one side platform, which is 6-cars-long. Hempstead, the terminus of the Hempstead Branch, has two sets of island platforms, each 8-cars-long. Woodmere, located on the Far Rockaway Branch, has two side platforms, each 10-cars-long. Northport, located on the Port Jefferson Branch, has one side platform, which is 12-cars-long. Bellmore, located on the Babylon Branch, has one island platform, which is 14-cars-long.
