There's no doubt that railway systems represent one of the most dynamic segments of embedded computing design. There's a lot for embedded systems to do aboard trains—ensuring both safety and precise control for the train, but also for the increasingly sophisticated entertainment systems installed on today's modern trains. Meanwhile, trains are evolving into moving Internet-of-Things (IoT) platforms, as system developers strive to leverage the many benefits of data collection and passenger monitoring. Even embedded artificial intelligence (AI) is finding its way into the mindshare of railway system developers. Exemplifying these trends, MEN Micro is a leading example of an embedded computer vendor deeply immersed in railway system technology development. Among its offerings are its line of EN 50155, ISO 7637-2 and IRIS certified electronics that are embedded into trains (and buses) for control, supervision, communication, passenger information, security and testing. Figure 1 shows an overview of the MEN's solutions along those lines. EN 50155 is one of a handful of standards targeted specifically for railway systems. Table 1 shows of summary of these standards.
