FIELD: railway transport.
SUBSTANCE: invention relates to organization and control of traffic on railways, particularly to track devices interacting with train and it can be used for recording passage of wheel. Proposed detector has wheel passage signal pickup. Field and receiving inductance coils of detector are installed along rail. Coil is connected through transformer to series-connected rectifier, filter, analog summer and comparator. Moreover, wheel passage detector is provided with compensating signal shaper. Summer provides correction of initial voltage level drift owing to control signal from shaper output.
EFFECT: improved reliability of recording of wheel passage.
