Alstom Metropolis C851E (Circle Line)

The Alstom Metropolis C851E (CCL) trains are the third generation of rolling stock for the Circle Line.

23 trains of three cars were purchased, to be delivered progressively into Singapore.

The new trains are fitted with condition monitoring systems to gather data from the equipment on the trains, enabling continuous monitoring of equipment health, allowing the operator to carry out predictive maintenance for the trains.

The current collector shoes for these trains to receive power from the third-rail electrification system are also equipped with a shear-off sensor, allowing the operator to react promptly when dislodgement is detected.

The Automatic Track Inspection (ATI) system will be fitted onto two trains, allowing concurrent monitoring of the running rails, trackside equipment and sleepers during operations.

Utilising Alstom's Urbalis 300 Communications-Based Train Control (CBTC) signalling system, these trains are capable of fully automated operations and can run without any train attendant on board.

History

Contract 851E for the design and building of 11 new Circle Line (CCL) and six new North East Line (NEL) trains was awarded by the Land Transport Authority (LTA) to Alstom Transport SA on 30 April 2018. The initial contract tender only included 11 CCL trains, with an additional six new NEL trains then included under modified contract terms.

These trains are purchased to cater for additional capacity when the North East Line Extension (NELe) and the Circle Line 6 (CCL6) begin operations in 2024 and 2026, respectively.

The trains are manufactured and assembled in Alstom's manufacturing facility in Barcelona, Spain, and shipped progressively to Singapore. The trains will undergo testing and commissioning works before entering passenger service when the CCL6 opens, boosting the fleet size by 17 per cent from 64 to 75 trains.

The LTA announced on 25 July 2019 the purchase of an additional 12 new trains on top of the initial order and will be delivered progressively from 2024. The additional 12 new trains will boost the total fleet size of the CCL to 87 trains and will cater for the expected ridership increase when the CCL6 is fully operational.

The first train arrived in Singapore on 11 March 2022, with several trainsets to be received by the upcoming Singapore Rail Test Centre (SRTC) in early 2023.
