ATSF 3751 heads to San Bernardino down the middle of the 10 Freeway on its way from Los Angeles Union Station to San Bernardino station to take part in both San Bernardino's National Train Day display and the city of San Bernardino's Bicential Celebration. The track here is former Pacific Electric, which has been slowly encased over time by the Ramona Parkway, the El Monte Busway, and the San Bernardino Freeway (successor to the Ramona). What was actually amazing to me was how many of the drivers didn't even seem to notice the train.
