I just finished the first 3 sceanrios from this pack (Hauling Heavy Freight on The Dover Massillon Sub) from the Railworks Scenario Shop.

If you have Ohio Steel2, I urge you to give this pack a try. The scenarios are very well done and provide an interesting "shift". From running the entire route to switching at Massillon, you won't be disappointed. The pack includes a version using the Dash-9 DLC and a version using a default engine. There is some other freeware needed, but the readme contains a list with links to the addtional assets.
Customer support has been second to none.
If you enjoy the scenarios from Smitty's, RRyards, FooteForward and Trains and Drivers, the Railworks Scenario Shop is a welcome addtion to the US route, scenario builders club.
