It's a busy, and rainy, morning in Fullerton as Metrolink train 707, a 91/Perris Valley Line train (Los Angeles to Perris-South), with F125 915 shoving, loads passengers on Track 3. On Track 2 is 146-car BNSF Railway Intermodal Stack train S-LBENSA1-19L (Long Beach CA to NS-Ashland Ave Yard IL), holding the main to allow, on Track 1, the faster Metrolink train 702, an eastbound 91/Perris Valley Line train, heading to Perris-South from LA, to get ahead of it. Metrolink F125 913 leads this eastbound. (Fullerton, California – March 21, 2023)
