Fully automated train systems? https://en.wikipedia.org/wiki/List_of_automated_train_system...

Not nearly as complex a problem as self driving cars, but I'd still rather not get hit by a train

Yes, not nearly. Not anywhere close to the complexity needed for self driving cars. Trains run on closed, limited, well-signaled infrastructure, which (comparably) makes it fairly easy to "avoid other trains" (as long as the signaling, coordinated externally, works--if it doesn't the train is likely programmed to just stop until it does again).

My understanding of trains is that most of the safety advances have come from better signaling, not the automation of the trains themselves.
