Very nice "rail scene"! Do you think this engine might be 3746 instead of 746? I am not that familiar with the Frisco 0-6-0s. Tom
I have no clue as to the actual number on the 746. This picture was one of about 100 pictures taken during the construction of the elevated portion of the Santa Fe through downtown Oklahoma City in the late 193's.
Reason I mentioned it, the Frisco had some 0-6-0s numbered in the 3700s. But their 700s were 4-6-0s. Tom
