"On an overcast day BN's SPD heads east into Rock Island, WA 10-9-82 with SD40-2's 8028/8066/8016/6363. At the time these 8000's series SD40-2 were everywhere. They must have been assigned to Interbay. Though I was probably not happy it was overcast, no doubt it would have been very backlit if the sun had been out. Can't recall the symbol SPD, probably something like Seattle/Portland to Denver."
