PROBLEM TO BE SOLVED: To provide a railroad crossing control system and a railway control system which can detect approach and passage of a train and intrusion of an obstacle without causing a great cost increase, and have high lightning resistance and high resistance against electromagnetic noise.SOLUTION: A railroad crossing control system includes an optical cable 11 laid along a railway track 12, light detection means 21 which detects scattered light in a light source that is connected to the optical cable and emits a laser beam to the optical cable, and in the optical cable, frequency analysis means 22 which frequency-analyzes an optical signal detected by a photodetector, and control means 23 which detects a train position based on a signal from the frequency analysis means and controls the railroad crossing equipment, where the optical cable is disposed at a train passage point intended to start an operation of the railroad crossing equipment in the railway track and a train passage point intended to end the operation of the railroad crossing equipment so that any section determined related to resolving power of an optical device cross the track.SELECTED DRAWING: Figure 2
