Re: Trains DO NOT deserve a second glance . . .
. . . and for the very reason you cited. "... it’s fairly easy to screw up a train." Unless the entire run is going to be guarded 24/7, that is the way it's going to remain, too. European rail is a little different from U.S. rail.
* In the EU, much, though not all, is commuter traffic, and across populated/observed land.
* In the U.S., much, though not all, is freight traffic, and across unpopulated/unobserved land.
