Train timetable for Xian to Hanzhong. Any overnight train availabe?

Well, no train runs between these two places currently. As I know, the overnight trains only run when the cole flowers blossom in spring.
You have to take the coach. South Bus Station and West Bus Station both have schedules to Hanzhong. But the last bus schedules respectively are 19:20 and 17:40. So no public transportation can take you to Hanzhong at late night.
