One of the Soo Line's ubiquitous wide-vision cabooses, caboose 3, is seen at the trap-rock quarry in Dresser, WI on a fall afternoon in 2001. Although Dresser is on the trackage the Soo sold to the Wisconsin Central in 1987, trackage rights were retained for access to this quarry, where the Soo got rock which they used as track ballast.
