The need to ensure compliance with emissions standards led to the development of an engine control unit with remote condition monitoring. Because train engines spend most of their time away from their home base of operations, Pennsylvania based Brookville Equipment Corp pairs a TMV TECU with Opengear’s ACM5000 line of remote data center monitoring equipment, with built-in 3G cellular connectivity, OpenVPN support, & GPS location for as close to real-time condition monitoring and data gathering of engine emissions status for an entire fleet regardless of location, leading to a drastic reduction in the time between when a problem arises and when the operators or maintenance staff become aware of it, enabling them to deal with the issue in a timely manner.
