I've noticed on the Big Sandy Webcam that trains heading west from Longview and then needing to go South towards Tyler actually go beyond the diamond, back up the connecting track onto the line heading North (Pine Bluff Sub?) and then proceed south across the diamond towards Tyler. There is a connecting track just beyond the diamond that would allow WB trains to make a progressive move and diverge directly on to the line to Tyler, so my question is why do they waste the time and effort to do the backing maneuver? Is it a signal issue, is the connecting track out of service? Just seems very odd that they would operate that way.
