ALSN (автоматическая локомотивная сигнализация непрерывная, in Latin - avtomaticheskaya lokomotivnaya signalizatsiya nepreryvnaya, meaning Continuous Automatic Train Signalling) is a train control system used widely on the main lines of the ex-Soviet states (Russian Federation, Ukraine, Belarus, Latvia, Lithuania, Estonia). It uses modulated pulses inducted into rails similar to the Italian RS4 Codici and American Pulse Code Cab Signaling. On high-speed lines the variant ALS-EN (АЛС-ЕН) is used which takes advantage of a double phase difference modulation of the carrier wave. thumb The name ALSN (АЛСН - автоматическая локомотивная сигнализация непрерывного действия) is composed of ALS, literally "Automatic Locomotive Signalling" (АЛС - автоматическая локомотивная сигнализация) and the variant designation N "Continuous Effect" (Н - Непрерывного действия). Other variants are built according to the same scheme like ALST (АЛСТ) for "Fixed Point Automatic Train Signalling" (АЛС точечного действия) and ALSR (АЛСР) for "Radio-Based Automatic Train Signalling" (АЛС с использованием радиоканала). The term ALS-ARS (АЛС-АРС) refers to "Automatic Train Signalling with Automatic Speed Regulation" (автоматическая локомотивная сигнализация с автоматическим регулированием скорости) used in subways which is a form of an automatic train control system.
