It would really help if people would stop calling this 'real-time', just because it creates the illusion. Real-time means: physical train slows down, communicates with all interested parties within a limited amount of time (for example: 20 milliseconds). Because of CAP, interested parties either show real-time update within 20 milliseconds, or display 'missing data', or sth. Generally, the latter situation is a failure condition (fails the RT condition).
