How to book a first-class sleeper train from Bangkok to Chiang Mai?

Hi everyone, I can't seem to book a first-class sleeper from Bangkok to Chiang Mai on February 2nd using the train company's official website. At first, I thought it was because I was searching too early. But now (December 3rd), it should be working. No trains show up for that date.



Is there another way to book this train ticket? Thanks so much.

Use Krungthep Aphiwat instead of Bangkok as your departure station.

Yeah, thanks—I did that. It worked, but too late, everything’s booked! Waitlist
