The San Bernardino Line is a Metrolink line running between Downtown Los Angeles east through the San Gabriel Valley and the Inland Empire to San Bernardino, with limited express service to Redlands. It is one of the three initial lines (along with the Santa Clarita and Ventura Lines) on the original Metrolink system. As of August 2016, 20 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. From Wikipedia
