Introduction of Planning and Development Department

We are performing the development of a supporting system to ensure the safety on the railway.
We have performed broad developments including an inspection device of wheel and a rail flaw detector with ultrasonic wave.
In addition we have developed a machine which attracts a driver's attention to prevent excessive speed or the false passage of a stop station and a railway location indicator of the train.
We are also performing the development of the labor saving machine.
We intend to continue developing the system aiming at the safe and comfortable transportation on the railway.

Introduction of technology

Introduction of technology

Wheel Flat Detector
If a damage of wheel surface (wheel flat) which was produced by a skid of the wheel or fever at the time of braking is neglected, it makes noise and vibration at running to cause uncomfortable riding and scatter a noise around the region along the railway.
In addition, it causes bad influence on rolling stocks and tracks, which in turn threaten safety. Therefore we have developed a device which can automatically detect rolling stocks where a wheel flat was produced.
This device, composed of several vibration accelerometers fixed to the rail, separates a flat vibration from a normal vibration at running to detect it accurately.
This device is introduced into many railway operators such as East Japan Railway Company, Central Japan Railway Company (Shinkansen), Kyushu Railway Company (Shinkansen) and Korean National Railways. The basic theory of measurement is becoming standard to detect the defection in the railway industry.

GPS Train Navi(Driver Support System)

GPS Train Navi(Driver Support System)
We have developed a driver support system using GPS technology to prevent interference with driving caused by a driver’s mistakes such as a false passage of a stop station.
This system was introduced into all the lines in Kintetsu Corporation on March 17, 2008, and into Nara line and Fukuchiyama line in West Japan Railway Company in the spring of 2010.
In addition, this system has been gradually introduced into other lines of West Japan Railway Company.

Train Traffic Rescheduling Support System

Train Traffic Rescheduling Support System
When a confusion of the train operation occurs at the complex structural station with many railways crossing at the same level or at the terminal station where departure and arrival of the trains are frequent, this system offers the images of the approaching car and information of the train set to a signal operator in advance. In this way this system can support the swift rescheduling of the train traffic.

Rail Profile Measuring Equipment

Rail Profile Measuring Equipment
Since this device measures the profiles of rails with reference to their upper fillets, all measurement data are represented on the same coordinate system. Rail profile change can be judged accurately by simply superposing the measured rail profile on a reference profile.
Inputting the measured profile data into the rail grinding support system makes it possible to establish an efficient rail grinding program.

Compact Rail Grinding Equipment

Compact Rail Grinding Equipment
Removing steps at insulated joints, welded joints and other joints by grinding in short time ensures low-noise and smooth traveling.
A portable, compact rail grinding device is more maneuverable and economical than a conventional rail grinding machine when grinding local sections of rails such as rail joints. In line with this standpoint, we have developed a grindstone that fits a rail and then developed a compact rail grinding device equipped with this grindstone.
