No. You change trains once, in Bangkok, and book each train as a separate ticket.
Take RP174 at 16:30, change in Bangkok and continue on EX75. The whole trip takes about 24h 25m, including 2h to change trains.
From about 446 THB per adult in total, on RP174 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.
