train was delayed by an hour, and they only informed on the boarding timing.
the cabin was filled with locals, the people behind kept talking in Vietnamese very loudly. seat was decent (if you're not a clean freak), but the toilet was horrible and stunk quite badly, could smell from the cabin away actually, thankfully we had masks on.
after alighting, we realised there were the better cabins (with better seats). advice not to take the lowest grade one
