As of July 2011, 21 trains run Los Angeles to San Bernardino on weekdays. It is the first of the seven Metrolink lines to run on both Saturday and Sunday, with 10 trains to San Bernardino on Saturdays and 7 on Sundays. Two Saturday and two Sunday trains would continue to the downtown Riverside station until July 5, 2014, when weekend service on the 91 Line began.
The Redlands Passenger Rail Project was a planned Metrolink extension to Redlands. As of 2011[update], service was to begin in the mid to late 2010s, with stations at Waterman Avenue next to the Inland Regional Center, the ESRI campus, Downtown Redlands, and the University of Redlands. As of December 2015[update], SANBAG decided that this second phase of the project, from the San Bernardino Transit Center to Redlands, would no longer be a Metrolink extension, but rather an independent system. SANBAG now plans to use diesel multiple units and have Omnitrans operate the system. However, San Bernardino Line express limited-stop trains would run on part of the extension, to the Downtown Redlands station. Construction is planned to begin in 2017 with the extension opening in 2020.
