 Part of the impetus for the project was the possibility of interconnecting with Amtrak’s Heartland Flyer at Oklahoma City for linking to Fort Worth and the rest of the Amtrak system.Concerns about the continuing viability of the Heartland Flyer have been voiced from time to time, as when in 2016 issues were raised centering on the subsidies paid by the states of Oklahoma and Texas for the service.However, the route has so far remained in operation.
