The South Florida RTA struggled to interact with CSX Transportation in its efforts to complete its Commuter Rail Upgrades project. While CSX had sold the corridor to the State of Florida, the railroad essentially still controlled it as operator of freight rail and maintainer of the railroad. The project started with pre-construction buy-in by the railroad and other partners to initial designs. The agreement specified that the upgrades would meet the current corporate design standards of CSX. However, as the project progressed, the railroad's design standards evolved, and the project incurred costly change orders to accommodate the new design standards. This led to cost overruns, and the project took a year longer than originally envisioned to complete. In the end, the South Florida RTA considers it a successful project, completed safely, with one-half the national average number of accidents for a project of this type, and reflecting a high level of quality. However, because of cultural and institutional issues, the project costs were higher and the agency had to come up with local funds to handle overruns.
