Challenges: Administration
• Jointly funded by USDOT/Federal Railroad Administration, TxDOT,
City of Fort Worth, North Central Texas Council of Governments
and two railroads
• Public funding changed the processes regarding Permitting, ROW
Acquisitions, Utility Adjustments, and Design Review Process
• Coordinating design AND construction w/ various Stakeholders
which included the City of Fort Worth, TxDOT, multiple developers,
Utility Companies, and Neighborhood Associations
• FRA/TxDOT required a “Flow-down Agreement” to be developed by
the BNSF and Union Pacific, which was incorporated into
Contract Documents
• Infrastructure which was designed and constructed by the BNSF
on behalf of the City of Fort Worth required the development of a
Community Facilities Agreement (CFA) which appropriated
funding by the BNSF versus the CoFW

So, why is this important?
• Nationwide Freight network
impacts
• Improved Commerce and
Mobility (just-in-time
inventory)
• One bottleneck affects the
whole rail corridor
• Large impact of multiparty
TIGER projects and PPP’s
• Importance of long range
transportation planning and
cooperative design
