The Land Transport Authority (LTA)’s Contract 851E for the procurement of 17 additional electric multiple unit (EMU) trains for the North East Line and Circle Line was awarded to Alstom Transport for ~S$250 million in April 2018.
The new trains are the third-generation rolling stock for both the NEL and CCL, which will supplement previous generations of Alstom Metropolis rolling stock. They were procured ahead of the opening of the North East Line extension (1.7km, projected 2024) and the Circle Line Stage 6 (4.3km, projected 2025).
The trains are manufactured and assembled in Alstom’s manufacturing facility in Barcelona, Spain and progressively shipped to Singapore from 2020 for NEL and 2021 for CCL. Thereafter, trains would undergo testing and commissioning before they are put into service when the extensions open.
On 25 July 2019, LTA announced that they would be purchasing 12 new trains from Alstom, in addition to the 11 trains that were procured in April 2018 for Circle Line Stage 6.
Revenue service for the Contract 851E trains commenced from 28 July 2023 on the North East Line.
Background
As the sole bidder for Contract 851E, Alstom Transport was awarded the contract. The trains were built as part of Alstom’s Metropolis family of urban EMU trains. While Contract 851E was originally offered solely for 11 Circle Line trains, modified contract terms added 6 North East Line trains for a total of 17 trains (comprising a total of 69 trainsets). An additional order for 12 Circle Line trains was made by LTA in July 2019, for a total of 23 Circle Line trains.
With the new trains, the existing NEL fleet was expanded by 14% from 43 to 49 trains and the existing CCL fleet increased by 36% from 64 to 87 trains. While being awarded under the same contract, trains built for the NEL and CCL differ in technical specifications owing to different electrification used on both lines.
North East Line
The 6 new trains will supplement the existing Alstom Metropolis C751A and Alstom Metropolis C751C trains on the NEL when the 1.7km long extension from Punggol to Punggol Coast opens in Year 2024.
The trains draw power from a 1500 V DC overhead catenary. They are fully automated (ATO GoA 4) and do not require an attendant on board. Each 6-car train (Formation: DT–Mp–Mi–Mi–Mp–DT) comprises two Driving Trailer (DT) cars at each end, and four Motor Cars (Mp and Mi). The second and fifth cars of each train (Mp) are equipped with a pantograph.
These trains entered revenue service from 28 July 2023.
Circle Line
The 23 new trains will supplement the existing Alstom Metropolis C830 and Alstom Metropolis C830C trains on the CCL when the 4.3km long extension from HarbourFront to Marina Bay opens in Year 2026.
The trains draw power from a 750 V DC bottom-contact third rail. They are fully automated (ATO GoA 4) and do not require an attendant on board. Each 3-car train (Formation: Mc1–Tc–Mc2) comprises two Motor Cars (Mc1 and Mc2) at each end, and an unpowered Trailer Car (Tc) in the middle.
Features
To enable a more robust maintenance regime, all the new trains are equipped with condition monitoring systems to gather data from equipment on the trains. This enables continuous monitoring of the health of the equipment and allows the operator to carry out predictive maintenance for the trains. Current collector shoe sensors on the new CCL trains enables the operator to react promptly and take necessary measures if any dislodgement is detected.
In addition, two of the new CCL three-car trains are each fitted with an Automatic Track Inspection (ATI) System, which enables monitoring of the running rails, track equipment and sleepers while the trains are in operation. The ATI System supplements existing track inspection activities for timely and more effective identification of rail and trackside components which require maintenance.
