Oklahoma Passenger Rail Association (OPRA, no currently working website), newsletter for Summer 2011:

Oklahoma Governor Mary Fallin signed a bill into law which creates a board to study passenger train service between the state's two largest cities, Tulsa and Oklahoma City. Funding to construct or operate the route has not yet been identified. Both conventional and high speed technologies will be considered.

Voters in Oklahoma City approved the MAPS-3 intermodal hub plan. A list of suitable locations was narrowed to 3, and then an area around the current Santa Fe Station used by Amtrak's Heartland Flyer was chosen. Besides that train, the facility could also serve a downtown streetcar circulator, commuter rail to Norman, Edmond, and Midwest City, bus rapid transit, and some local bus routes. Interestingly, ridership projections assume that there will be 2 frequencies on the Heartland Flyer to Fort Worth, 2 on a new route to Wichita, and 6 daily high speed trains to Tulsa. Preliminary design shows one Amtrak track, 2 through mains for freight trains, one track for commuter trains, and one for Tulsa high speed trains. Provisions would be available to widen the elevated structure to the east to built yet another platform if needed.

Meanwhile, the aforementioned streetcar line in downtown Oklahoma City would be built in two phases. One would be constructed along with a new Convention Center, and open in late 2016. The second streetcar phase would open sometime in 2020.

Construction has begun on a new multimodal bridge project near Tulsa that will handle vehicular traffic as well as freight and possibly passenger trains. The bridge over the Arkansas River would be an expansion of the existing I-244 westbound bridge. The bridge would be closed (with traffic diverted to the eastbound span) while it is retrofitted for trains. Increased freight activity has rendered the existing plate girder bridge obsolete. For potential passenger trains, the bridge could carry light rail or streetcars to West Tulsa, regional rail to Bixby, or even a high speed rail corridor.
