It seems, the rail can't be placed due to the cliff not beeing marked as to be exploded. This only happens sometimes, maybe because the problematic cliff part is between two properly marked cliffs, that sometimes take the middle piece with them upon boom.
I can reproduce this when loading a certain save with the cliffline intact, and having the placement done by the stations bots (not my personal ones).
I use Alien Biomes (which has two parts for size reasons, both of them I have running), auto-deconstruct, qucikbar import/export, and text plates.
Log file is attached, I failed to upload the save, maybe it's to big (22mb). I tried to walk to the offending cliff in a smaller (earlier) save, but it seems, the map looks different there. Both the version of factorio and alien biomes have changed since, so that sounds plausible. If needed, we can maybe find a way around this (like my googledrive).
