New Tyne Tunnel: Integrated SCADA System
The New Tyne Crossing project involved the design and build of a second vehicle tunnel under the River Tyne, and the refurbishment of the existing vehicle tunnel. Due to increases in traffic in the original contraflow, a second tunnel wasproposed to create a uni-directional system after the refurbishment of the original tunnel, increasing safety and decreasing traffic congestion.
Ematics were awarded the full SCADA and Data Comms design and build contract, including sub-systems integration and CCTV Video Wall and provision of a new control room fitting out with desks and video wall housing.
- Dual Redundant SCADA.
- Dual Redundant Traffic Control PLC system.
- Dual Redundant Plant Control PLC system.
- Ethernet Data Communications Network.
- CCTV Video Wall
- Historian Reporting System
- SCADA Integration of Video Incident Detection System
- SCADA Integration of CCTV System
- SCADA Integration of Emergency Telephone system.
- SCADA Integration of Fogtec Mist System.
- SCADA Integration of Public Address System.
- SCADA Integration of Network Management System.
- Phase 1 – New Southbound Tunnel Operational in bi-directional mode.
- Phase 2 – Refurbish Northbound Tunnel and both Tunnels operational each in uni-directional mode.
TCMS SCADA System
The Traffic Control and Monitoring System (TCMS) for the new Tyne Crossing provides monitoring and control functionality of the following equipment:
- MS3 Variable Message Signs and Matrix Signs on the approach gantries.
- Advance Signs on the Southbound and Northbound approaches.
- MS4 Variable Message Signs and Matrix Signs at the tunnel entry portals
- MS3 Variable Message Signs and Matrix Signs at the tunnel exit portals.
- Lane control and speed restriction signs in the tunnels.
- Traffic lights and barriers on the approaches.
- Traffic Loop Detectors external to the tunnels.
- Overheight vehicle detection on the tunnel approaches.
- CCTV coverage at the portals.

EPCMS SCADA System
The Environmental Plant Control and Monitoring System (EPCMS) for the new Tyne Crossing provides monitoring and control functionality of the following equipment:
- Tunnel Jet Fans
- Pollution Axial fans in Adits
- Tunnel Pollution Sensors
- Tunnel, Extrenal and Adit Airflow Sensors
- Differential Pressure Sensors
- Gallery Pressurisation Fans
- Modulating Dampers
- Sump Pumps
- Level Sensors
- Sump Ventilation Fans
- Mist System Valves and Pumps
- Tunnel Message Signs
- Escape Gallery Message Boards
- HV and LV Boards


SCADA Subsystem Integration
As part of the project works, Ematics were engaged to develop suitable interfaces such that all tunnel subsystems could be integrated directly in to the SCADA system. This integration included the following subsystems:
- CCTV Video Feeds and Video Wall Video selection.
- Video Incident Detection
- Public Address Systems including zone selection
- Emergency Telephones.
- Tunnel Fire Suppression System.
- Radio System.
- Traffic Signs

SCADA Incident Support
The approach to incident control adopted for Tyne was for the SCADA system to support the operators in their decision making process, rather than having the SCADA system automatically initiate any of the subsystems. An incident in the Tunnel is detected by one of the following events occur:
- Smoke detected by VAID cameras
- Stopped car detected by VAID cameras
- Fire detected by Heat Detectors in Service Gallery
- Fire detected by Break Glass units in Service Gallery
- Fire detected by Break Glass units in PDPs
- Unauthorised Access detected by EDP open
- Unauthorised Access detected by Fire Door open
- SOS Telephone in use (1 in each PDP)
- Manually Initiated by an operator

CCTV Video Wall
A total number of 96 CCTV cameras are available which can be displayed across the monitors using varying combinations views from single to 16 way split. The camera views can also be configured to run on a rotation across the monitor wall. These screen layout configurations can be saved for each operator allowing for easy customisation of the layouts.


PLC System

Ethernet Network Infrastructure
A new fibre backbone was designed and installed in the tunnels and buildings using the Cisco® Catalyst 3750G series Ethernet switches. These switches are multilayer with Fast Ethernet and Gigabit ports and featuring Cisco StackWise™ technology, allowing for the creation of highly resilient networks.
Cisco 3750G switches are used to provide a 3Gbps backbone during normal conditions, failing to a 2Gbps and then to a 1Gbps backbone in fault conditions. These switches are installed at strategic locations and are stacked to create a single virtual switch with a single IP Address, thus simplifying the topology of the network and reducing the convergence time of the network should a fault occur.

Network Infrastructure Features
The network infrastructure was not just designed to support all the sub system upgrades provided by this project such that a common Ethernet solution could be provided through all sub systems, but to protect the investment of the project by future proofing the tunnel and the works by providing a modern expandable and resilient network structure capable of expansion without compromising reliability or performance. Some of the features provided by the infrastructure are:
- Cisco Based Solution
- Stackwise Technology for easy expansion
- Broadcast segmentation of subsystems with VLANs
- Virtual LAN (VLAN) support.
- Inter VLAN routing.
- Per port Unicast, Multicast & Broadcast Storm Control.
- Switching loop protection using rSTP and MST (Rapid Spanning Tree).
- No single point of failure.
- Independent Network Management System.
Network Management System
A Network Management System (NMS) called Whatsup Gold was installed and configured for all switches to trigger alerts based on switch and port status including CPU usage, high bandwidth, switch uptimes and many more features that are required to provide a fully functional network management system.
- Predictive and pre-emptive monitoring of networks and systems infrastructure and core IP services.
- Automated network discovery and mapping.
- Alert management platform, featuring easy to use alarms, alerts and notification capabilities for real-time operations support
- Quick navigation via Web and Windows consoles.
- High security and configurable role-based management.
