FIELD: transport engineering; high-speed vehicles.
SUBSTANCE: proposed air lock contains compartment with ramp-gate and tube-pass made for arrangement of train with cars. Length of cars is equal to length of span between supports designed for mounting air lock and main tube-passes. Three-dimensional frame is made on support located at air lock-to-main tube-pass border. Unit of separating air lock paraboloid gate is mounted on horizontal guides of frame for displacement by means of telescopic hydraulic cylinders. Said unit is provided with opening to pass vehicle from air lock tube-pass into main tube-pass and back. Springy plate seals are mounted on end faces of main and air lock tube-passes.
EFFECT: provision of ecologically clean safe and cheap transport system at multiple increase of speed of running.
