<p>One thing I'm wondering: How would the UP train pass the commuter train without a switch being set? The UP train was apperently going to pass the Metrolink train somewhere, presumably at the station, so wouldn't the Metrolink train have to pass over a switch set for the opposite way at some point, wouldn't it? Or would the switch be thrown shortly before the UP train arrived?</p><p>Does this make sense? </p>
