Well, you’ve not specified what shoot down incident you’re talking about but I’d argue the fault probably lies with the trigger happy air defenders not IDing their targets.
VFR pilots aren’t even allowed to use GPS for primary navigation. Those don’t fly bigger airplanes but visual flight is still taught and used to this day
“GPS” would mean GNSS satellite systems like GPS, as well as terrestrial systems like AGPS and base-station-based triangulation. Given that modern train control systems involve transponders alongside the railway line, these can be used as well. Railway lines running through tunnels in particular would rely on non-satellite systems.
Trains don’t need gps, do they?
I mean, neither do cars or planes.
Planes don’t? That plane flying off course and getting shot down lead to GPS signals being made accessible to the public.
It helps a lot, but planes were navigating the world long before the invention of GPS.
They also used to go off course and get shot down.

My guess is he means Korean Air Lines Flight 007, which was caused by a mistake the Pilots made and a trigger happy/incompetent sovjet Airforce.

Rail lines use multiple redundant navigation and safety systems. GPS is one of them.
