TRA Cruise Style Train Travel

I see some advertising but TRA and travel agents are not selling tickets. Are there cruise style train trips available in Taiwan?

Kind of false advertising. A cruise includes a room on the boat to sleep and unpack. Nothing like that in Taiwan. Minimally need to stay in hotel at each stop.

Kind of fun to have a room on a train where it would stop for day then move to next town but always have hotel room on train and food if possible.
