The San Bernardino Mountains are shrouded in clouds, creating a chilly backdrop as Union Pacific expedited intermodal train ZLADV01 21 heads east, bound for Denver from Los Angeles. This train has just conquered Cajon Pass and is speeding across the BNSF’s Cajon Sub. UP ET44AC 2615, ES44AC 7655 and SD70ACes 8748 and 9044 are leading this train, which is about to meet BNSF westbound train S-LPCLHW3-17, which has already received a clear signal on Track 1.
