The head-end crew, including a number of Mechanical Department officials, posed with the still-new 6318 as the M-4 was recorded by a Baldwin photographer on one of its break-in runs in coal train service on the Beardstown Division late in 1927. Note the air horns behind the stack and white flag. Note too the single-chime whistle mounted on the large live steam line, just ahead of the rear sand dome. The air horns won't last more than a few months, and the whistle would be moved forward, adjacent to the horns' former position. I count nine people in this photo, possibly a crowded cab on this date.
