Hello, I'm new to this group, so forgive me if I'm doing this wrong. I'm going to be flying into Porto in late Oct and then need to travel by train to Santiago (and then eventually Sarria). I've been hearing that there may be issues with train strikes/lines. What does this mean in terms of reliability? I'd rather not take the bus as I can be prone to car sickness. Would Renfe be the best option or the Portuguese interregional one (can't recall the name)? Thanks for any advice.
