I've never encountered a train on these tracks, but I still haven't quite shaken my fear of them. There are several tracks in this area all rather close to each other and all in (infrequent) use, so sometimes while taking a few pictures along these I will hear a train and freeze. That moment is quickly followed by scrambling to collect my things and move to the side, only to realize the train isn't anywhere near these tracks. Still, better safe than sorry. I do always pick a spot where I can see quite far off in either direction, so if one does approach there will be plenty of time to remove myself and my tripod from the scene.
