Abstract

A tunnel ventilation system (TVS) on railway lines has been installed for the primary purpose of providing safe evacuation conditions for people and contributes to the energy efficiency and sustainability of the system. In Malaysia, the Klang Valley Mass Rapid Transit (KVMRT) project which began operation in 2017, was designed with a comprehensive TVS. The ventilation system is typically tested and commissioned before the railway is opened to the public to ensure that it meets safety and performance standards. As part of the operation, TVS will be controlled remotely using the Integrated Control Supervisory System (ICSS), which provides retrieval of field inputs and remote control of field devices. Hence, Interface pre-test between TVS and ICSS is conducted to validate the approved interface design, monitoring and control functions whichever is applicable. For this study, the Interface Pre-test is conducted at one of the underground stations of the MRT Sungai Buloh Putrajaya line which is Chan Sow Lin Station. The pre-test includes tests for the Input/Output (I/O) List, a redundancy test, and a test for the Corrective Maintenance Work Order. After the completion of the pre-test, rectification works were conducted to rectify the findings from the pre-test before proceeding with the official Interface Test. To minimize the risk of errors and faults during the live operation of the rapid transit system, a maintenance manual is required to serve as a guide for the end-users, which are the rapid rail staff who operate the system. This manual provides detailed instructions for the maintenance and operation of the TVS, including troubleshooting procedures to identify and rectify any issues that may arise during operation. This maintenance manual was reviewed by the Design and Technical team from MMC – Gamuda KVMRT (T) Sdn Bhd, the project's main contractor, before been approved by MRT Corporation, the government agency responsible for the development and operation of the Mass Rapid Transit system. The review ensured the manual met project specs, technical standards, and safety criteria for the railway system's operation
