Legacy hardware and operating systems are battle tested, having been extensively probed and patched during their heyday. The same can be said for software written for these platforms – they have been refined to the point that they can execute their intended tasks without incident. If it is ain't broke, don't fix it. One could also argue that dated platforms are less likely to be targeted by modern cybercriminals. Learning the ins and outs of a legacy system does not make sense when there are so few targets still using them. A hacker would be far better off to master something newer that millions of systems still use.

Tell me you know nothing about cybersecurity without telling me you know nothing about cybersecurity. Wtf is this drivel?

Cybersecurity != Safety Critical

It is when safety-critical systems are the target of a cyberattack.

Doesn't sound like this system is safety critical. You should be more worried if some hacker can change train signs from stop to go. If you ever ride on a train and see steel boxes by the side of the track, those are control systems and they run up and down the line. They might be locked, or possibly alarmed but that's about the extent of their protection. A simple attack would be to just take an axe to one, or set fire to it. A more sophisticated attack could snoop on the profinet traffic and do something evil.
