table stakes, but people still mess up on it constantly. The "yeah, but that's only a problem if you're an idiot" approach to this kind of thing hasn't served us very well so it's good to see something actually being done.
Trains shouldn't collide if the driver is correctly observing the signals, that's table stakes too. But rather than exclusively focussing on improving track to reduce derailments we also install train protection systems that automatically intervene when the driver does miss a signal. Cause that happens a lot more than a derailment. Even though "pay attention, see red signal? stop!" is conceptually super easy.
