I happened to catch a UP office car special train by complete coincidence on Wednesday morning, 10/12 heading westbound in the Columbia River Gorge:
UP OCS Train passing Bridge of the Gods (Cascade Locks, OR)
UP OCS Train arriving at Multnomah Falls (Bridal Veil, OR)
UP OCS Train departing from Multnomah Falls (Bridal Veil, OR)
The first video was shot from my room at the Best Western PLUS Columbia River Inn at Cascade Locks, OR while I was waiting to film the westbound Amtrak Empire Builder across the river, which was imminently due to pass through on the Washington side (BNSF Fallbridge Sub). I was completely surprised by seeing this special train running on the Oregon side (UP Portland Sub).
