The invention relates to a rail transit magnetic track brake provided with horizontal magnet exciting coils and applied to rail transit vehicles. A magnet exciting coil assembly of the magnetic track brake is transversely and horizontally arranged in an iron core unit. The magnet exciting coils are totally arranged in the iron core unit. The magnetic flux generated by the magnet exciting coil is almost completely closed in an iron core. Large brake force is provided by means of a few magnet exciting coils or low exciting current. The utilization rate of the magnetic flux of the magnet exciting coils is increased, and the conversion rate of brake force is increased. The magnet exciting coils are completely arranged in the iron core. Two end assemblies and the iron core unit form an inner cavity wrapping the magnet exciting coil assembly together, and it is guaranteed that the magnet exciting coils can be fully protected; and the reliability of the magnetic track brake is improved. When the rail transit magnet track brake acts, the lower end face of a barrier clearing plate is in contact with the upper end face of a track prior to the iron core unit, and foreign matter possibly existing on the surface of the track is removed; and it is guaranteed that pole shoes are in good contact with the surface of the track, and large brake force is obtained.
