BNSF Railway train M-SDGBAR1-05A (Regular Merchadise; San Diego to Barstow) holds the middle main, train Z-LACCHI7-06L (Priority UPS-LTL Intermodal; Los Angeles to Chicago) overtakes it. The M-SDGBAR would hold this position for over an hour as various BNSF and UP trains leapfrogged ahead of it. This location, Lugo, on Cajon Pass' east side, is also the end of triple track, which is why the lowly train from San Diego was held so long for higher priority trains. (April 6th, 2013)
