i stayed at my friend's place tonight, and got used to hearing K5 series horns blasting by with coal and grain trains, but early in the morning I heard a RS3L or something of the sorts go by. I was thinking it could have been a transfer move for Marathon, but i've never seen the two Corman leased units even move. I think they are #1607 & #1827, the two units i'd like to know more in particular, as I think they're still leased by Marathon for oil car switching. Thanks
