ABSTRACT
The Compass line and Bukit Panjang line are the first Mass Rapid Transit (MRT) system and Light Rail Transit (LRT) system completed in Singapore respectively. The Compass Line was opened for revenue service since 1987. It comprises of 57 passenger stations with four power intake substations. The Bukit Panjang Light Rail Transit (BPLRT) was opened for revenue service since 1999 and comprises of 14 passenger stations with a single power intake substation.
This paper presents the design considerations, approach and challenges in the planning and execution of power intake upgrading and associated works at the Compass Line and BPLRT. The paper also presents some of the innovative engineering solutions implemented to ensure there is no disruption to the train operation and at the same time maintaining the revenue service level as usual. Lastly the paper briefly discusses some of the considerations that are being applied to the on-going power supply system upgrading works in the existing Jurong East MRT station.
Keywords: Power supply system, Power intake, Upgrading works, Railway.
