last night, 6/30, I caught Westbound Amtrak train 67 with a P42 pulling an AEM-7. I assumed an equipment move of the extra P42 from the bridge shuttle service
Don't know if this qualifies as "unique equipment" as it was a "position-unique" sighting -
Yesterday morning train 495 headed south with cab coach 9650, coach 82675, loco 102 facing north,
being "kissed" by loco 72 facing south. First time I've seen 2 P42s nose-to-nose on a road job, albeit trailing the move.
