Abstract: A railway condition monitoring device includes an acquirer structured to be attached to a railway vehicle bogie and acquire state information on one or more state of vibration, speed, acceleration, sound, reflected light, image, temperature, humidity, and a wheel diameter, a determiner structured to be attached to a bogie, perform a determination of a state of a track on which the bogie travels or a state of the bogie based on the state information acquired by the acquirer, and provide the determination result, a transmitter structured to be attached to the bogie and transmit the determination result to an outside of the bogie, and a power supplier structured to be attached to the bogie and supply power to the acquirer and the transmitter.

Abstract: There is provided a foreign material removing device of a track turnout portion which can tightly attach and fix nozzles to a rail belly portion stably without machining a rail itself. A foreign material removing device of a track turnout portion which has point rails which can move to contact and move away from stock rails of the track turnout portion, and which removes a foreign material dropped between the stock rail and the point rail, includes a piping unit which includes a plurality of nozzle portions which spray compressed air to remove the foreign material, and the piping unit includes a close-contact arrangement structure in which the piping unit is arranged in close contact with a lateral surface of the stock rail opposed to the point rail.

Abstract: A foreign matter removing device Y1 for use in a turnout X1 is provided with a base rail 100 and a tongue rail 200. The foreign matter removing device Y1 is provided with an inlet member 4 including an inlet channel 44, the inlet member 4 extending in the width direction of the base rail 100 in a region lower than a bottom surface B1 of the base rail 100; and a connecting portion 22 including a communication channel 22c for communicating a nozzle portion 21 which injects a foreign matter removable medium to between the base rail 100 and the tongue rail 200, and the inlet channel 44. The connecting portion 22 is connected to one end portion 41 of the inlet member 4 in the region lower than the bottom surface B1 of the base rail 100.

Abstract: Provided is a foreign matter removing apparatus at a track branch, and a nozzle used in this apparatus that are capable of sufficiently securing foreign matter removing performance as well as significantly reducing generation of noises. In the nozzle for the foreign matter removing apparatus at a track branch, compressed air supplied from piping is injected from each nozzle element. Slits are formed in each nozzle element, a sloped portion is formed at a front end of the nozzle element, and this sloped portion opposes a tongue rail.
