Recently, the Land Transport Authority opened the door to the media for the first time at a light rail depot in Singapore's Shenggang that had just been fenced off. When the reporters aimed their cameras at the newly added second maintenance building and the photovoltaic panels on the roof, a power supply system constructed by China Railway Electrification Bureau was quietly connected to the heart of this soon to be expanded threefold rail transit.

Triple expansion to accommodate new fleet

The expansion project of Shenggang Bang'e Light Rail Vehicle Depot will start in 2022 and is expected to be completed in 2027. The land area will be expanded from 3.5 hectares to 11.1 hectares. The main reason for expansion is to provide parking and maintenance space for the newly purchased 25 two car trains. The newly added maintenance building can maintain two sets of trains simultaneously, with a maintenance capacity 1.5 times higher than the old facility; The newly built test track is specifically designed for performance testing after vehicle maintenance. Seven new trains provided by Mitsubishi Heavy Industries have been put into operation, and the remaining 18 trains will be deployed by the end of 2028, increasing the passenger capacity of the light rail network by 15.8%.

Chinese company wins bid for Singapore power supply for the first time

The power supply system upgrade and renovation project is undertaken by China Railway Electrification Bureau International Engineering Co., Ltd. in the form of a consortium. This is the first time that China Railway Electrification Bureau has won the bid for the Singapore Land Transport Authority project, and also the first time that a Chinese enterprise has won the bid for a power supply system project in Singapore, a developed country. Aurecon from Australia is responsible for the design, Sato Industries from Japan is responsible for the main construction, and the pattern of four companies working on the same platform is being carried out simultaneously at the Shenggang construction site.

Photovoltaic annual power savings exceed gigawatt hours

The roof of the expanded vehicle depot will be extensively covered with photovoltaic panels, which are expected to save at least 1520 megawatt hours of electricity per year, equivalent to the annual electricity consumption of 354 households. At present, the construction of the main structure has been completed, and the next step will be the joint debugging and testing of the track connection and signal power supply system, which will be carried out in four steps: dismantling the existing concrete facilities, restoring the power supply lines and trackside signals, independent testing of each system, and comprehensive joint debugging of the entire system. As new cars gradually replace old ones and green electricity replaces commercial electricity, this light rail corridor connecting Shenggang and Bang'e is undergoing a systematic upgrade from hardware to energy.Editor/Gao Xue
