While some of the National Limited route has been torn up, the Norfolk Southern restored the former PRR mainline through Ohio. I believe that route ran originated in Pittsburgh and headed West through Ohio and Indiana with stops in Youngstown, Canton, Akron, Lima, Crestline, Fostoria, and in Indiana in Ft Wayne, Napanee, Warsaw, Valpariso, and Gary. While not the National Limited route it does illustrate that those states can be crossed Westward and South of the Lakeshore and Capitol Ltd route. There are tracks to Indianapolis from that route and tracks west from Indianapolis but Its quite a stretch that we will see passenger service there again.
