Is Big Boy the most photographed steam locomotive of all time?

As part of the inaugural tour , Big Boy 4014 is shown pacing from Limon to Denver, Colorado.

The Big Boy class locomotive was conceived to eliminate the need to double head locomotives when hauling long freight trains up the Wasatch Mountains.
