The order, worth around €70m, includes delivery of the dc and ac rail electrification system as well as overhead power lines for the NELe.
The lines will be upgraded with the Siemens Catenary System Standard Rigid (Sicat SR) aluminium overhead busbar system. Siemens say that compared with conventional overhead power lines, Sicat SR has a lower installation height and a low voltage drop, as well as a high current-carrying capacity, short-circuit resistance and reduced contact wire wear.
The extension to the Circle Line is scheduled to open in 2025 and will take its total length to 39.5km. The Circle Line Stage 6 project will effectively close the loop by connecting Harbour Front station with Marina Bay, adding three new stations at Keppel, Cantonment and Prince Edward. The line will improve connectivity from the west of the island to the central business district as well as new developments taking shape around Marina Bay. Alstom is supplying communications-based train control (CBTC) for the extension which will support driverless operation.
The 2km NELe will run from the current terminus at Punggol to Punggol Coast station, supporting residential developments in the area. It is expected to open in 2023.
