ESSO-M Axle Counting System

ESSO-M is a new generation axle counting system. It complies with the world trends in railway signalling sector.

ESSO-M controls vacancy/occupancy of a track of any configuration and length. It is an alternative to track circuits. ESSO-M integrates with upper level systems via relay-contact interface.

ESSO-M is applied on stations and interstation lines of public and non-public railways, in metro and high-speed light rails. The system can be used for backup of track circuits and detection of tail end of a train at pedestrian crossings.

Set of Equipment

Outdoor Units

  • DKU/DKU-M/SKM Wheel Sensors with Sensor Clamps.

SKM Wheel Sensor is a functional alternative to DKU-M Wheel Sensor and has an improved construction. SKM Sensor processes data on vibration, speed, movement direction and wheel location. The Sensor has an advanced immunity to traction current noises, SKM Sensor is applied in various climatic conditions. 

Indoor Units

  • KBR Evaluator Unit, PLR Counting Board and PLI Communication Board.
  • UPSP Axle Counter Adapter.
  • USKS and USKS-E Interfacing Unit.

USKS-E Interfacing Unit ensures link with remote counting posts via redundant serial Ethernet Interface. Remote wheel sensors could be connected with ESSO-M and ESSO-M-2 systems.

  • USSO Counting Posts Expansion Unit.

USSO allows enables ESSO-M and ESSO-M-2 systems to control switch sections of any size. In case of large switch sections the equipment cost is reduced for 15 %.

Diagnostics and Monitoring


DS Diagnostic System comprised as software and hardware complex allows live tracking of system condition, transmits diagnostic information to upper level systems and log events. Information gathered by DS streamlines maintenance and troubleshooting as well as enables additional functions: tracking of a train movement along the station, maintenance of trackside equipment as per actual wear condition.

ESSO-M Work Station is designed for live monitoring of system status of the station, logging and viewing of information and troubleshooting. On booting ESSO-M Work Station displays the list of stations available for monitoring with their miniaturized layouts. Scale of the selected layout can be adjusted. Clicking on section displays detailed information on its status.

Customer reviews about the ESSO-M system

  • ESSO-M
    Privolzhsk Railway Infrastructure Department - branch of JSC "RZD"
    Privolzhsk Railway Infrastructure Department thanks Promelecronica for reliable cooperation and partnership on the Russian Railways project implemented in 2015. The project was aimed to prevent people injury in train movement area. Promelectronica equipped seven pedestrian crossings on one- to five-track lines with ESSO-M Axle Counting System at Privolzhsk Railway.
