Metro-North Railroad
New York State Territory Database

Geographic (inset) and schematic views of the MNR RAILSIM database.

RAILSIM was used to create a GIS-based database for the Metro-North New York State territory, and generate C&S Block Plans and C&S Routing (Control Line) Plans. The territory includes 404 track miles, encompassing the railroad’s Hudson, Harlem and New Haven Lines. This work was integrated into the Upper Harlem Line territory from Brewster North to Wassaic, which had already been modeled in RAILSIM.  The completed database includes:

• Identification of railroad-related C&S wayside entities, such as towers, Central Instrument Houses (CIH’s), bungalows and cases;

• Overgrade and undergrade bridges and structure designations for all bridges;

• Public and private grade crossings;

• Crossing names, milepost and AAR designations;

• Track centerline;

• Platform configurations and limits;

• RAILSIM station codes;

• Wayside signals, master locations, code change points and other insulated joints;

• Switches and movable point frogs;

• Grade and curve change point designations;

• Maximum authorized speeds, speed restriction limits and Signal Design Speeds;

• Signal control line data, including route-by-route wayside aspects and code rates;

• Catenary structures; and

• Predefined views for stations and interlockings
