Grand Canyon Railway's beautifully liveried MILW FPA's - both an FPA-4 unit and an FPB-4 unit, pull a matching consist through Willaha, AZ, on the railroad's regular excursion, passing the railroad's 2-8--0 No. 29 steam locomotive. The MLW FPA-4's were ran as a favor during a Lerro charter which also featured 2-8-2 No. 4960. Typically, the line utilizes much newer F40's.
