          Images representing the O.B.M.C.S.Features:

OBMCS uses Controller Area Network (CAN) technology to achieve a modular architecture in which sensors and actuators can easily be integrated into the system in a "Plug and Play" fashion
	Sensors and actuators in the OBMCS are interconnected on a CAN bus communication network, which uses an open standard communication protocolThe OBMCS System Includes:

Temperature sensors to monitor bearing temperature
	Accelerometers to monitor bearing and wheel defects and derailments
	Tri-axial accelerometers on the main sill above the bolster bowl to monitor truck hunting, vertical pitch and bounce and logitudinal impacts
	Proximity sensors to monitor brake piston stroke for excess travel and proper retraction
	Wireless intra-train communications and telemetry
	A bearing generator (one per car) provides power for OBMCS
	The third generation OBMCS integrates the on-board monitoring system with remote control of the advanced components from the locomotive
