, the LIRR has 8 active control towers. All movements on the LIRR are under the control of the Movement Bureau in Jamaica, which gives orders to the towers that control a specific portion of the railroad. Movements in Amtrak territory are controlled by Penn Station Control Center or PSCC, run jointly by the LIRR and Amtrak. The PSCC controls as far east as Harold Interlocking, in Sunnyside, Queens. The PSCC replaced several towers. The Jamaica Control Center, operational since the third quarter of 2010, controls the area around Jamaica terminal by direct control of interlockings. This replaced several towers in Jamaica including Jay and Hall towers at the west and east ends of Jamaica station respectively. At additional locations, line side towers control the various switches and signals in accordance with the timetable and under the direction of the Movement Bureau in Jamaica.
