Various modes were studied to reinstate a more regional service since at least 1991. Funding for the active incarnation of the project headed by the RCTC initially came from the SunLine Transit Agency, with further support by federal grants, the California State Rail Assistance program, Caltrans, and the FRA. Long been seen as the preferred operator, Amtrak was formally identified in the Alternative Analysis phase. Service is envisioned to start at Los Angeles Union Station and run over the route of the Southwest Chief, switching to the valley's Union Pacific line at Colton to run over San Gorgonio Pass and terminating at Indio or Coachella. Operations include one afternoon and one evening trip in each direction for two daily round trips.
