Throughout the United States, public transportation is undergoing a renaissance. Investment in mass transit is growing and improved and expanded public transportation services will attract increasing numbers of riders on state-of-the-art systems in metropolitan, small urban, and rural areas alike.
Transdyn supports the transit market with systems and services by designing and implementing integrated computer, communications, and security/surveillance systems used to manage all aspects of public transit operations.
We provide turnkey services to combine various subsystems into a homogenous, fully integrated, high-availability, secure control and information management system. These subsystems include:
- Office and Central control systems
- Situational management systems
- Power and facility management systems
- Field control units
- Communication networks
- Passenger information systems (PA and VMS)
- Radio and telephone systems
- Situational Awareness and Analytic Systems
- CCTV surveillance
- Access control and fire systems
We have worked with leading transit agencies like BART and Toronto Transit Commission to build solutions that manage their rapid transit systems.

SCADA System
Owner: Toronto Transit Commission
Location: Toronto, Ontario
PDF Version
System Description: Every weekday, an average of 1.2 million people ride the subway,
buses and streetcars of the Toronto Transit Commission (TTC). The
TTC owns and operates subway and surface transit systems for the
City of Toronto, Ontario and provides mass transit for the entire
Metro area.
Development of TTC’s new Power SCADA System was awarded to
Transdyn in early 1999 as a joint effort with Alstom Signaling
(formerly GRS). This system monitors power distribution to all transit
lines (subway, trolley and light rail), ventilation subsystems, and
passenger station facilities.
The power management capabilities of the SCADA system are very
extensive with many operations fully automated, e.g. scheduled
shutdowns, emergency ventilation, and emergency trip recovery.
Operators are able to monitor and control power to track segments,
substations, and surface street catenary subsystems. They can also
view switch and power status, execute grouped control commands,
execute and monitor pre-placed power, generate system and user level
reports, and archive system generated data.
The SCADA system is based on a fully redundant network consisting
of high-performance, high-availability servers, workstations, front end
communication processors and field RTUs. Transdyn's DYNAC®
software is a fully integrated SCADA package that provides all the
features required for a power distribution system plus many of the
unique requirements for a rail transit system.
AirTrain Facility Management SCADA System
Owner: The Port Authority of New York & New Jersey
Location: Newark Liberty International Airport, NJ
PDF Version
System Description: The Newark Liberty International Airport is the sixth busiest airport in the nation, serving over six million people every month. In order to transport patrons from the New Jersey Transit Authority rail system, outlying parking lots and rental car agencies to the terminal area, the Port Authority of New York and New Jersey replaced its bus system with an automated people mover monorail system.
Under a subcontract, Transdyn provided the Facility Management SCADA System (FMSS), which monitors and controls all power distribution, station fire and station security devices. As part of the new $500 million transportation system that provides automated transport between the airport terminals and ground transportation, the system, managed by Transdyn’s DYNAC® software, monitors and controls various facility and vehicle support systems that are critical to the safe and secure operation of the monorail system. The FMSS provides several custom control sequences including detecting and correcting system faults, emergency power removal sequences, power factor correction, and guideway and rail heating control.
Owner: Office of the Architect of the Capitol
Location: U.S. Senate, Washington, D.C.
PDF Version
System Description: U.S. Senate Subway, located in Washington, D.C. is a fully automated, driverless people mover that provides transport between the U.S. Capitol and the U.S. Senate (Hart & Dirksen) office buildings.
Transdyn provided an Automatic Vehicle Operation (AVO) System and a SCADA System. AVO system is responsible for speed control, braking, station docking, door control, switch control, and interaction with the Automatic Vehicle Protection (AVP) System. The systems are managed by Transdyn’s DYNACTM software and monitor power, vehicle position and operational modes.
