摘要： A railroad light signal fixture, either for railway/highway grade crossing application or right-of-way use, includes a housing (40 or 76), each having a signal light aperture (42). There is a lens structure (44,46 or 78,80) covering the aperture and there is a source of illumination within a housing opposite the lens structure. The source is provided using a laser (48,50,52,54,56 or 70) which provides for light within a specific colour spectrum as required for the specific application.

摘要： A railroad crossing gate electrical control system for moving a crossing gate in up and down directions and providing snubbing protection to gate movement in failure modes includes an electrical motor having two diametrically positioned permanent magnet poles (24, 26) and two series connected electromagnet poles (28,30). There is an armature (20) which rotates inside the poles. There is a motor and snub relay (46) which has contacts (F1-F4, B1-B4, H1-H4) connected to the armature (20) and the series connected electromagnet poles (28,30). A terminal board (32) has movable contacts which are connected to the motor and snub relay (46) and to a relay coil for moving the contacts of the motor and snub relay (46). A source of power is connected to the terminal board (32), with the movable terminal board contacts controlling the application of power to the motor snub relay coil (48) and the relay contacts for causing up and down movement and for providing snubbing of armature movement during up and down gate movement and gate failure modes. An overspeed control (50) is connected across the armature for limiting armature speed.

摘要： A system is disclosed for monitoring condition of a railways installation such as a points machine. The system includes a plurality of sensors (S1, S2, S3--SN) associated with elements of the installation for monitoring parameters indicative of operating capability of the installation. The system includes means (12, 23) for processing the monitored parameters to determine whether the parameters are changing relative to reference values and to determine whether the changes are indicative of an increased risk of malfunction in the installation. The processing means may include a digital computer programmed with condition monitoring and fault detection software. A method of monitoring condition of a railways installation is also disclosed.
