Nucleus Graphical User Interface provides seamless communication between rail traffic personnel and field equipment. Train Control, Traction Power, Station Operations, Alarms, Schedule, and Public Address subsystems can all be controlled intuitively, accurately, and safely through Nucleus.

Train Control displays allow users to conveniently view and manipulate interlockings, station platform locations and associated commands, signal controls, and train tracking information. Nucleus GUI communicates with SCADA and Train Control servers to display indications as reported by PLCs, VPIs, and other field processors.

The integrated Train Tracker reads track occupancy indications to display real-time information for each train on the mainline. The Train Tracker can import car data to display car number, operator, headway, line assignment, and direction of travel for each and every train in or out of service. With integrated scheduling, the train tracker will also display borders indicating whether a train is on time, early, or late.

Nucleus integrates with your organization's existing enterprise network to track operators, schedules, train information, and more. Here, the scheduling system tracks actual departure times of each train on the mainline against their scheduled departure times for each location, and logs early, on-time, late, or annulled trips in the schedule record.


Pushbutton commands for switch and route alignment are more user-friendly than hard-panel systems. Simply select the desired entrance or exit, and choose a command. This eliminates the need to memorize various pushbutton positional functions, as required on outdated hard-panel systems.


Traction Power screens display the state of all breakers, associated third rails, disconnect switches, voltage and amperage analog values, and breaker configuration. Breakers can be controlled directly at the breaker graphic or at the associated power rail for immediate de-energizing in an emergency scenario.


Nucleus includes public address control to deliver audio and visual communications to passengers and other members of the public on platforms and in surrounding station locations. Messages can be created, edited, and scheduled in this interface. Nucleus also supports live message delivery by rail traffic control personnel, transmitted from central control. Nucleus is capable of integrating with several different LED and LCD signs, and various audio equipment.
