Motive power on the Pekin branch

In an effort to learn more about operations on the ATSF Pekin branch I've been digging through old clearance cards and train orders from the branch. In doing so I was able to get a glimpse of what motive power was being used over the years.

On the layout I'm modeling the fall of 1959.  The realism of my current set of motive power is constrained by what is available in n-scale.  I'm currently using RSD-5s, GP-9s, and F-7s for freight power, and a mix of F-3s and F-7s for passenger power.
