Adding to this, self driving trains tend to run on restricted tracks that are isolated from roads, walking paths and other trains. For example, a metro. So it doesn’t need to do things like look out for manual drivers and pedestrians. Also, automatic train control, ATC, is already widely implemented for manually driven trains and a very manture technology, and full self driving is simply an extension of that as opposed to a brand new technology.
Less degrees of freedom so the decision-making process is a lot easier for the onboard systems.

Oh god I meant to write the opposite 😑: why aren’t autonomous trains more common since they are easier to implement.
Sorry, I was not sure whether your comment was sarcastic or not so I answered it seriously. :|
