RailAcoustic® which is designed and manufactured by Enekom, apart from all other broken rail sensing methods, works on the principle of applying a specific frequency of vibration at a certain point and then sensing this vibration both from a sensor located near to the signal injection point and from another sensor which is located at a far away point.

Basic characteristics of the RailAcoustic® are as follows;

  • It can be used satisfactorily at the rail systems which are rendered continuous mechanically and electrically by a welded joint,
  • It can work independently from the ballast resistor value,
  • The system works completely isolated from the electrical properties of the track and it can sense the broken segments on any AC, DC or unelectrified tracks,
  • The system modules can be easily be installed or dismantled without any damage to the rails,
  • Performance testing has been done satisfactorily on an existing high-speed railway track which is in compliance with UIC60 standards,

It works reliably and responsively under all weather conditions.

Already, the most commonly used rail crack sensing method is the use of track circuits that work with the basic principle of electrical continuity of the rails.

However, this method mostly may induce misdetection as a consequence of using the track as a line of return flow concurrently.

RailAcoustic® (RKAS-V1 model) Broken Rail Detection System which is being developed and manufactured by Enekom is working on the basis of sensing the resonance with a significant frequency generated on track from a point at far location. With this recent and unique system which the application for 2 patents have also been done and the first system testings on a high-speed railway line are accomplished, a fracture or a crack on the rail section lying betwee the resonance applied point and the detector at far location can easily be perceived and this information is conveyed to control and data center via a fiber optical communication line.

RailAcoustic® has already been introduced into the national and international markets.

On the field, one RAG100, the signal application unitand one RAR100, the signal sensing unit are mounted on to the exterior surface of the track on every 2 kilometers. RAG100 is designed as to be easily installed and demounted on the trackmechanically. Both the installation and the long-term usage of this module does not require any mechanical intervention such as punching or welding and also a damage on the static structure of the track with long-term use can not be discussed. A sensor is installed on track at a distance of 1 meter to each signal application unit, which are connected on the same electronic control cabinet.

On the rail equipped with these modules, the signal applied at a certain point on the rail is immediately measured by the sensor which is just next to the signal application unit.If the signal is at the reference level and if this is perceived by the system then the relevant system board in the control cabinet conveys this respecting informationto the sensors which are positioned at 2 kilometers on the right and on the left of the signal application point through the fiber optical network communication system.

Two neigbouring sensors, which retrieve the information regarding the applied signal and the exact application time via the fiber optic networking system and which are at a distance of 2 kilometers, start to work for signal processing. The detectors which obtain the signals at the predicted time frame decide if there is a damage on the track by comparing the related signal information with the reference level and transmit the consequent information to host computer of the central control station again through the same fiber optic network.The system modules are also capable of processing the reflected signal coming from the faulty areas and retrieve a highly detailed crack and fracture information regarding the rail segment which is under test.


RAG-100 : RailAcoustic signal Generator
RAR-100 : RailAcoustic signal Receiver
RASP-100 : RailAcoustic System Process
CCSM-100: Control Center Software Module

RailAcoustic signal Generator (RAG100): This signal generator module is an electromechanical unit which operates with the commands coming from the central control room computer thru the track-side fiberoptical communication system. Its main task is to apply a mechanical signal on to the rails at certain times.

Rail Acoustic Receiver (RAR100): This signal sensing module is attached to the rail for sensing the mechanical signals generated by RAG100 It first catches and processes the signal and communicates with the track-side electronic boards for additional signal processing and communication.

RailAcoustic System Process (RASP100): This electrical control cabin is located along the track at each 2 Kms distance to each other for housing the electronic boards, power supply and the fiberoptic network communication controller. It is made of stainless steel and IP65 rated.

19” Rack Mount Enclosure: System’s electronic boards are housed in this aluminum enclosure. It is located inside the electrical control cabin.

Electronic Circuit Boards: A number of electronic circuit boards for signal processing, driving the electromechanical system units, supplying power to the system components and IP based network communication boards.

Control Center Software Module (CCSM-100): A central command and monitoring program for operating the system under the supervision of a system operator. The system consists of a computer with a multi screen display, a program running in this computer, a data base operation for controling, monitoring and remote accessing to each system module in real time.

Why RailAcoustic ?
We can summarize the major characteristics of RailAcoustic® technology with a number of shortcut features:

It works purely on acoustic principle.

It performs reliably under all weather conditions.

It is suitable to use with continuously welded or insulated railway tracks.

No possibility of interfering with any signalling equipment.

It is easy for installation and removal from the rails.

It detects the rail breaks very early. It is the most reliable and effective method of detecting rail breaks in time, because the signal is picked up directly from the rails.

It detects rail breaks continuously. It is real time. It operates remotely and automatic.

Self Learning and Adapting Algorithm For All Conditions

The most distinct characteristic features are:

Generates an acoustic signal with a very special characteristic.

It is exempt from all climatic conditions.

It is a self learning and adaptive system to all conditions.
