Systems like trains need a reliable monitoring network that helps engineers to have access to all forms of vital information such as speed, pre-departure tests, brake gauges, alarms, schematics of the train and options that give the status of any system in any part of the train to any level of detail desired. Including the activate-menus to obtain instantaneous information critical for safe and efficient operation, even when entering a tunnel. Interaction with passengers, Before and after boarding the train, with basic train information such as the destination etc is included as well which is needed for efficient transportation. Trains fall into a network management scenario known as continuous installation. There is no set time when it is safe to assume that the topology of the train is fixed. Train cars get added, removed or swapped at any time.
