Union Pacific and their Columbia River route

JohnQuilter:

Ariels of the Mosier, OR area make me wonder about the practicality of two tracking only four miles. What is the difference between two tracks and a siding if a train has to stop and wait 30 minutes for a meet anyway? It looks like the trackage through that area is pretty slow going, so an effort to two track ten or fifteen miles may be more constructive and have more success with regulators. The four miles situation strikes me as only an effort to make points with upper management that probably doesn’t have a clue about the area.
