If you're looking for a major US route to model consider the CSX RF&P Subdivision. This sub is the former Richmond, Fredricksburg and Potomac railroad running from Richmond, VA, to Washington, DC - 110 miles. It features 10 daily Amtrak trains, including Auto-Train; 16 daily VRE (Virginia Railway Express) commuter trains and at least 18-20 CSX daily freight trains. In addition, the Amtrak Crescent (formerly Southern Railway) runs on the north end of this sub before turning southwest toward Atlanta and New Orleans.
The RF&P was a bridge line, with a slogan of "Linking North & South," on a system that stretched about 113 miles. Until around 1965 RF&P originated less than 5% of its freight tonnage, probably less than any other Class I railroad. For much of its existence the RF&P connected with the Chesapeake and Ohio Railway, the Atlantic Coast Line Railroad and Seaboard Air Line Railroad at Richmond. At Alexandria and through trackage rights to Union Station in Washington, D.C., connections were made with the Pennsylvania Railroad, Baltimore and Ohio Railroad and the Southern Railway. It connected to the Washington and Old Dominion Railroad at Potomac Yard and interchanged with the Chesapeake and Ohio Railway at Doswell. It and the former Conrail properties are the only CSX lines to have cab signal requirements on their entire system.
The railroad is all 2-3 tracks signaled for bi-directional running with frequent cross-overs for maximum service. Rolling stock from the DTG Miami to West Palm Beach would fit almost all the demands. All in all, the RF&P would be an interesting route with lots of action and variety.
