Under the general direction of the Train Control Upgrade Project Manager and Lead Engineer, the Assistant Engineer performs system engineering work on the project. During the design phases, the Assistant Engineer supports the project by reviewing engineering designs and documents submitted by the CBTC Supplier, and works on systems integration between the train control system and various wayside components such as switch machines, vehicle detection systems, and interlockings. The Assistant Engineer also assists a dedicated team working on software integration between the CBTC system and other technology systems such as CAD/AVL, asset management systems, SCADA systems, and databases. The Assistant Engineer contributes to the civil engineering design for enabling works, including developing electrical drawings, schematics, and plans for cable, conduit, or other connection infrastructure to accommodate the train control system. The Assistant Engineer participates in design reviews, activities, and technical coordination meetings between the Supplier and the equipment installers. During construction and testing phases, the Assistant Engineer monitors construction progress and compares field conditions to design drawings, participates in train control system testing from the control center, wayside, and vehicles to ensure testing, safety certification, and commissioning of onboard equipment comply with specifications, and develops installation and testing plans to facilitate the process.
