A model of an EMD SD9 in the colors of the Riverside, Waterton & Atlantic RR is now available for free on my website. There are two engines included, one in "original" and one in "simplified" livery. They are of course fictitious, like the route they are intended for.
A word of caution: while these engines are QuickDrive ready, they only really work on routes that have the Kuju\RailsimulatorUS assets enabled by default. So to be able to use them on the Lakeside route, you must first enter the route editor once, tick the checkbox for Kuju\RailsimulatorUS in the assets filter, and save the route.
You can download them here:

EDIT: A small update is now available (May 30). This allows the engines to be used without having to tick the Kuju\RailSimulatorUS assets in the editors. More info is on the download page linked above.

Cheers!
Michael
