“It’s called Positive Train Control”
—
I’m thinking more along the line of GPS, such as you have in cars. Except it’s overlaid by train tracks instead of streets. So you know where you are and whats coming up, something independent of just human sight and memory.
Make sense or no?
The FRED units at the end of a train and the trackside sensors perform much of that function, but only to relay the condition of the train to the conductor and the dispatcher. Positive Train Control is the real answer to these kinds of operator errors.
