$120M was budgeted in the American Recovery and Reinvestment Act (ARRA) grant for the Mainline Grade Separation Project. That $120M needed to pay for the following:
a 3,400' long trench w/ a single CSXT track, but wide enough to accommodate a second mainline track---trench needed to be deep enough to accommodate double stack containers
temporary realignment of the CSXT SF-Line to maintain CSXT traffic during construction
temporary realignment of the NS Mainline ( which would have had to be two tracks) and a new temporary interlocking with the SF-Line
new connections from NS and CSXT to the ADM flour mill
O-Line bridge over the trench and two additional roadway bridges over the trench.......
a new flour load out facility for ADM----which requires extensive modifications to the existing ADM flour mill
All of this for $120M!!!
The biggest challenge was that you had a project that impacted three Fortune 500 companies, ADM, CSXT, and NS-----but none of them wanted it. The project would have required agreements with all three corporations. ADM wanted a brand new flour mill.....NS didn't need the project b/c the controlled the interlocking.....CSXT wanted a double track trench---but really didn't need the project. Even with the expected growth of freight traffic, additional passenger trains through Graham due to relocating the passenger station to the Gateway Station site, and future commuter trains, there are still at-grade rail crossings in Chicago, Fort Worth, and Colton, CA (now grade separated) that see waaaay more trains. The Mainline Grade Separation was a great project, but the finances, corporate challenges, and ARRA grant timeline requirements made it a difficult project to carry through design, right of way acquisition and construction.
