Theoretical research of influencing of mine railtrack muddiness on the joint-joined locomotive in the mode of braking by devices realizing brake force in the point of contact of a wheel with a rail is carried out. The terms of locking the wheels by the brake moment during the move along rails with different strength of muddiness are ascertained. Maximum and minimum coefficients of rolling friction differ 2,63 times but maximally possible moments differ only 2,40 times.
