Abstract. Theses are presented to the experimental data on the study of the speed of the creep wave propagating in a hundred-meter continuously welded rail containing a welded joint made by electrocontact welding, and defects such as vertical wear of the head formed due to insufficient durability. The speed of the creep wave decreases significantly at the junction of the rails and has a peak with distance from it. The speed of the creep wave in the area of defects has a maximum value in the center and dips at a distance of 100 mm from it to the left and to the right along the length of the rail. To excite the creep wave in the rails, a U-shaped ultrasonic transducer was used with an oppositely located emitter and receiver at a distance of 72 mm.
