And when 4449 made the move from Brooklyn Yard to the depot on the UP mainline, UP called out "SP" 4449? I have been curious, does BNSF prefer to use DLMX instead of the "SP" initials when 4449 is operating a special on their lines?

Interesting Q, Mitch.

Google-searching for [DLMX dispatcher] turned up this pic, whose caption reads, in part, "Doyle McCormack's SP 4449 (the white text on the second tender reads "DLMX 4449")".

So we then search for [reporting mark dlmx], and find "DLMX - Daylight Locomotives and Machine Works, Inc." Here's the buzzfeed info: [www.buzzfile.com]
