I am proceeding with train booking for Greek train to travel to/from Athens~Thessaloniki from trainose site. [ Greek train site ]
I saw Coach A till coach B2 are big coaches.
Coach B3 onwards seats are small.
Does that mean the bigger coach are sleeper coach & the smaller coach/seats are just for sitting?
I am taking over night train to/from that's why want to make sure I book sleeper coach.
Thanks & Regards,
