I rode this train about 27 years ago. I believe it was about 11 1/2 hrs. long ride. If using Amtrak, there is a bus/train combo, though the bus portion is negligible as it is extremely short, about 15 mins. The train ride is listed as 9 hours 7 minutes on the Amtrak schedule, which would make the total trip around 9 hours, 30 minutes. You can see the link before for more details.
