No. You change trains once, in Bangkok, and book each train as a separate ticket.
Take RP170 at 18:20, change in Bangkok and continue on SP25. The whole trip takes about 35h 19m, including 9h 25m to change trains.
From about 462 THB per adult in total, on RP170 and RP133 in the cheapest available class.
At least one hour at the same station. Long-distance trains, especially from the south, are often late, so a wait of 2–3 hours is safer. If you change between Hua Lamphong and Krung Thep Aphiwat in Bangkok, allow extra time to cross the city.
