What is the Triangle Symbol on Hoppers

[NW Mailing List]

Matt,

     Some looked like Dobie Pads (ask your Mom) and some like journal 
box size car wash hood scrubbers. I absconded with a pair of the Dobie 
type from a box car in a scrap yard and ended the constant hot box 
problem on the pilot truck of #33 when it was on the Hocking Valley Scenic.
