Speed Lettering

Doug Harrop Photography • May 1, 1991

 

In March of 1991, Southern Pacific introduced a new logo, called "speed lettering", inspired by the stacked Rio Grande logo. It was first applied to a group of rebuilt GP40M-2s by MK in Boise, Idaho. Initially, a smaller version of the logo was applied to SP 7107-7111, later adopting a larger version with SP 7112 on April 15, 1991.

 

Doug was on hand to catch the first two units with the officially adopted logo leading an EUCHX train through Ogden, Utah.

 

In total, SP applied speed lettering to 1,035 locomotives including new acquisitions from EMD, GE, rebuilt MK, and Southern Pacific, Rio Grande, and St. Louis Southwestern repaints.
