The Arizona State Rail Plan (SRP) is the first comprehensive assessment of the stateís rail needs and was initiated in response to the increasing involvement by ADOT in freight and passenger rail issues. The SRP serves to identify the current rail system, to determine infrastructure needs, and to have rail projects included in the state's long-range planning processes to improve regional and statewide safety mobility. The principle purpose is to convey the magnitude of the rail needs in the state and set forth a policy framework through which strategic actions can be taken to realize the full potential of passenger and freight rail transportation.
