A train consists of “one or more railway vehicles capable of being moved. It may consist of a locomotive (sometimes more than one) to provide power with various unpowered vehicles attached to it. It may consist of a multiple unit, i.e. several vehicles formed into a fixed formation or set, which carry their own power and do not require a locomotive. A train may be only a locomotive running light (deadheading) to a point elsewhere on the railway. A train may carry passengers, freight or, rarely nowadays, both” (source: RNE glossary). In the Smart-Rail project passenger trains are out of the scope.
Relationships:
• A train consists of vehicles (and has a count of number of vehicles)
• A train has a train identification, type, weight, length, speed, axle weight, brake type, number of axles and gives an indication if it carries dangerous goods.
