AR doesn't have money available to subsidize any train. TN would think Memphis already had train service and would rather spend their own money on trains servicing other cities without any services today, like Nashville, Knoxville, and Chattanooga. Likewise, MO wouldn't be interested spending more than they already do for a train to Memphis when there are cities within the state without services, like Springfield and Joplin.
Obviously there's enough interstate traffic that could support a train along I-40, but much of that traffic extends beyond Little Rock to Memphis. For a train to work, it'll have to be a much longer train, at least from Raleigh all the way to Albuquerque. A train that long would be long enough to not require any state subsidies. Additionally, the Sunset Limited follows I-10 a great distance, yet it doesn't attract sufficient ridership to warrant a train more than thrice a week even with the nation's 4 largest city, I'm afraid a train along I-40 would see worse ridership.
