There are all kinds of isolated systems that trigger warnings but the thing that seems to be missing everywhere is a centralized simulation with all the data in it. Or perhaps a series of simulations each slightly further in the future. If any variable changes run it again until it reaches its time stamp.
For example, it shouldn't be possible in 2026 for a vehicle to get stuck on the crossing (with cameras) without the train driver getting a notification. You can even power down an entire track if it's obstructed. You might not want self driving, self breaking seems quite desirable.
Depending on where, there can be lots and lots of small crossings. The cameras themselves might not be that expensive, but keeping them in working order is very nontrivial.
Just pay for it? Look, the camera here works just fine:

If you can prevent just one of those (and if we ignore injury, trauma and death) it should cover expenses for quite some time.
