Abstract The problem of locomotive traction formation remains as one of the most important problems of railway transport. This is due to a random component in the friction coefficient describing wage wheels adhesion with the rail surface. The coefficient of adhesion varies depending on several factors: weather conditions, railway surface quality, speed, etc. Formation of the traction are often performed by automatic systems with use of a linear dependences. Fall of adhesion is determined by the derivative of angular velocity of wage wheels rotation or by comparing rotation speeds of several wage wheels. The follow-up traction decrease is usually implemented as a corrective measure. This approach has some obvious disadvantages. In the paper we propose a system of adhesion moment estimation in contact point if "wheel–railway". As a means for observer design we use methods and principles of the synergetic control theory. In the theory of synergetic control the set of criteria for the control system is usually expressed in the form of an appropriate system of invariants. Invariants play the role of control objectives, they enforced a given technological problem, and the synergetic synthesis procedure reduces to process of finding control laws, which these given invariants are satisfied. The availability of information about current adhesion conditions will allow to construction a high-precision adaptive control systems for locomotive electrical drives to solve a number of problems: the problem of energy saving; the problem of maintaining the required or maximum a train velocity; the problem of maintaining the maximum of adhesion coefficient in contact "wheel–railway". The results of the simulation of synthesized evaluation system torque adhesion in contact "wheel-rail", which indicate the implementation of this goal; the transition process is about 0,3 s.
