and yes, it's quite early, but the thing is: - the night train leaves at 18:50 - the only train to Latour after this one would arrive at around 18:00 - this line is like, systematically about 1 hour late at the end of the line
for a return trip I might risk it (although in this case I'm certain I wouldn't make it), since it'd only mean I get back home later, but you know
in any case, I'm just going through this route to explore it. I'll probably go through Cerbère/Perpignan next times, it has a better schedule and is a more reliable line (and even AVE)
