Building a new network for Railway Stations
In an effort to mordernise and enhance the operational efficiency of railway stations, a new Optical Transport Network was built. The case study explores the reasons behind the project, the challenges faced , and the solutions implemented to achieve a state -of-the art network infrastructure.
Background: The railway stations were in dire need of network renewal. The existing infrastructure was outdated and lacked the capabilities to support the growing demands of modern railway operation. The new network aimed to address these issues by providing a robust and reliable solution.
Objective: The primary objectives of building the new network were:
1- To renew all stations with a new Optical Transport Network for 30 km at 10 GbE.
2 – To include mission – critical network active equipment and access control, physical security video surveillance, and emergency audio for passengers.
3 – To establish a new Operation Control Center (OCC) with SCADA ( Supervisory Control And Data Acquisition), a Building Management System (BMS), and video wall.
Challenges: The project faced several challenges, including:
1- Infrastructure Issues: The old equipment and lack of infrastructure capabilities to control the railway line were significant problems that needed to be addressed.
2 – Security and Surveillance: Ensuring the safety and security of passengers required the integration of advanced access control, physical security, and video surveillance systems.
3- Operational Control: The need for a new Operation Control Center with Scada , BMS, and a video wall to monitor and manage the railway operations effectively.
SOLUTIONS
To overcome these challenges, the following solutions were implemented:
1- Optical Transport Network: A new Optical Transport Network was built for 30km at 10GbE, providing a high-speed and reliable communication backbone for the railway stations
2- Mission – Critical Equipment : The network included mission-critical network active equipment , access control, physical security , video surveillance, and emergency audio systems to ensure the safety and security of passengers.
Network Telecom System: Active Equipment Infrastructure Network all over 13 stations. More than 500 enclosure with industrial Switches for railways platforms and Energy SSE. More than 500 video Surveillance IP cameras. More that 700 IOT Sensors via RS-485 /Modbus vs IP infrastructure. Scada System Telemetry integrating for IOT Gateways managed Centrally.
IOT SCADA BMS Telecontrol: Scada System Building management system. Video Surveillance and Audio integrating Access Control, Fire and Flame alarms. All done into the new OCC video wall.
