I went from St Louis to KC Mo and it was only 36 dollars per ticket, one way.
Ticket prices often vary, depending on the date of travel. Prices may vary by a lot. To find a ticket price, go to Amtrak.com and put in the trip information. If you qualify for a discount, put that in. The websites will show you available trains and the cost for the trip you have chosen on a given day. If your trip day can be any day, try other days of travel to see if you can find a cheaper fare. On my recent trip from Boston to San Diego, the price varied $400, depending on the day of travel. Good luck.
