Can I travel together with my girlfriend / boyfriend in the same cabin?

Yes, you can travel in the same cabin.
Mixed gender is not a problem for the Thai trains.
In case you are booking a single seat at the 2-place VIP compartment, you will be placed together with the same gender person.

Please note:
"Ladies only" carriages are for ladies only
