Stanley Feinsod Business Development Manager Transit Systems Engineering Emeryville, CA Streetcar System Controls

• Communications to/from operators • Passenger information • Status of service • Status of electrification • Status of equipment • Emergency and incident management • Maintaining headway and frequency Desired Functionality

• Traction power – Substation status-control – Status of breakers and switches – Ability to quickly de-energize sections – Alarms and fault tracking – Action logs Desired Functionality • Operations - Monitor and Control – Track individual trains-sectional occupancy – Direction of travel-route – Intersection monitoring – Station locations – Two way communications – Incident management – Headway and spacing management – Data acquisition and reports Desired Functionality • Passenger Information – Schedule – Arrival times – Canned messages from central – Special messages – addressed to individual stations or all stations – Messages inside cars – Visual messaging and audible messaging Central Office-Operations Control Center

• Real time - command and control • Visual data • Communications technology • System management • Hands on operations management SCADA Software Installation for the Oklahoma City Streetcar System

• What is the Nucleus Command System? • How Rail Systems benefit from SCADA software • How OKC’s Streetcar system is monitored and controlled • Lessons learned from the OKC Streetcar Project • Discussion & Q/A What is the Nucleus Command System?

• Nucleus is Supervisory Control and Data Acquisition (SCADA) software

• Features custom-made Human Machine Interface (HMI) “Nucleus Workstation” specifically for rail transit applications

• Hardware installed in a Central Office so Streetcar/Rail operators can monitor and control systems in real time Nucleus Command Offers Many Functions for Light Rail & Streetcar Systems Nucleus: An Advanced SCADA Solution for Rail Transit Nucleus Command: Installed and Operating Successfully in Rail Systems Nationwide

San Francisco MUNI Oklahoma Streetcar System Project Installing Nucleus Command Software

Project Objective: • Provide ability to control, monitor & administer entire Oklahoma City Streetcar system in efficient, modern, easy-to-use control system Project Scope | Smarter & Safer Streetcars

Nucleus Command equipped the 4.2 mile Oklahoma City Streetcar system with state-of-the- art SCADA technology . . .

“Nucleus enables the interfacing of operators in the control room with equipment in the field through a modern, integrated system by delivering the simplest and most cohesive interface to users.” Real-Time System Status Display User-Friendly Graphical Interface Display Nucleus Command Supported by Embedded Oracle Database

The Embedded Oracle Database is the main repository for network data, including SCADA and passenger information subsystems. Oracle Database contains all control system indications, controls, analog variables’ most recent values, calculated data point values, and manually entered data. OKC Streetcar Nucleus Project Seamlessly Went Into Revenue Service in December 2018 Lessons Learned: Oklahoma Streetcar Project

• SCADA/HMI software was designed, installed and put into service in less than 12 months

• Training was essential –first time users – supervisors and managers –had to be familiar with the GUI and control systems

• Communications systems had to be fine tuned-drops, multiple carriers, debugging essential

• The OKC operations staff “pleasantly surprised” – promises kept

• Six months of operations and no stated problems affecting utility of the system

• Supervision, capacity and smooth operations of streetcar network were accomplished Discussion/Q&A: SCADA Use in Streetcar Systems
