When someone says "Santa Fe!" everyone thinks Fs in Warbonnet:
But the Santa Fe also used Geeps in passenger service:
On early AM run from Williams Junction to Grand Canyon c.1962.
No mistaking what railroad you are riding.
Horsepower and mulepower at Grand Canyon. Just through those trees is the South Rim of the Grand Canyon. Those Geeps just brought a trainload of people to the Canyon and those mules and their buddies are gonna' take some of them into the Canyon.
