Nice photo.  Your description of the steam locomotive lists a 4-6-0.  However, looking at the wheel configuration of the steam locomotive in your photo shows otherwise.  I think you captured 4-8-4 CB&Q #5629.

The details are wrong. The steam locomotive is clearly not a 4-6-0; it's either a 4-8-2 or a 4-8-4; and the 3011 clearly pertains not to the steam locomotive, but to the Diesel peeking out from behind the steam locomotive's cylinder.
