The invention provides a railway condition monitoring sensor device attached to a railway bearing of a railway vehicle including at least one vibration sensor; means for detecting movement of the railway vehicle; a control unit for processing at least the signals obtained by the vibration sensor to determine a health parameter indicating the bearings state of health. The control unit triggers measurements based on at least one predetermined condition; and a wireless communication device for communicating the health parameter to a monitoring and control server. The control unit configured to be operated in an energy-saving sleep mode and in at an activated mode. The control unit is configured to switch from the sleep mode to the activated mode upon detecting that a predetermined set of conditions is met. The predetermined set of conditions includes the condition that the means for detecting the movement detects that the railway vehicle is moving.

A system continuously monitors bearing temperature and wheel surface condition. The system may include a button contact sensor for sensing wheel bearing temperature and a measuring laser for detecting wheel breakage. The system may also include a vibration sensor, sound sensor, and a load sensor. Each sensor is in communication with a receiver/transmitter and may be mounted to the railcar by way of a friction lock magnetic mounting. Computer means may be used to store, analyze, and present the collected information for use in deciding whether, for example, the train should be slowed or stopped. A solar panel may provide power to the components.
