Northeast Corridor - New York to New Haven
This route covers the stretch of the Northeast Corridor from New York City to New Haven, Connecticut. It includes both Metro-North's New Haven Line out of Grand Central Terminal and Amtrak's main line out of Penn Station, which converge together at New Rochelle, New York.
Dovetail developed two separate signal scripts for the Metro-North portion of the line (from Grand Central to New Haven via New Rochelle) and the Amtrak portion (from Penn Station to New Rochelle), a curious decision given that both railroads share the same Pennsylvania Railroad-derived pulse code signaling system in real life.
Penn Station to New Rochelle
The signals on the Amtrak portion of the route send messages in the form of
sigN, where N is a numeric code that communicates the aspect. The codes seem to be the same codes used by the Philadelphia to New York, North Jersey Coast Line, and Morristown-Essex Line renditions of the Northeast Corridor.
Grand Central to New Haven
The signals on the Metro-North portion of the route send messages in the form of
Ncc, where cc is a numeric code that communicates the aspect. The following codes are used:
The different meanings of the
N.. message types are unclear. It seems that most of the time, you will get
M.. messages, unless you encounter a downgrade, in which case you'll get a
M..R.. message, or an upgrade back to Clear, in which case you'll get a
To simulate power changeovers, Dovetail marked the end points of the route's third rail and overhead catenary systems with special signals. These emit the following messages:
||Overhead catenary start|
||Overhead catenary end|
||Third rail start|
||Third rail end|
||AI overhead to third rail switch|
||AI third rail to overhead switch|
Type 1 speed limits represent visible speed posts. Type 3 limits represent signal speeds. There are no type 2 limits.
