The Alstom Metropolis C851E trains are the third generation of rolling stock for the North East Line (NEL).

Six trains (six cars each) were procured, and they are expected to enter service in tandem with the 1.7km North East Line extension, projected to open in 2023.


Background

Main Article: Alstom Metropolis – Contract 851E trains | Land Transport Guru

Contract 851E was initially offered solely for 11 Circle Line trains in March 2017. 6 more NEL trains were added under modified contract terms, and awarded to Alstom Transport in April 2018 as the sole bidder. In July 2019, 12 more CCL trains were added to the order.

Train Line Quantity Formation Electrification Signalling
Alstom Metropolis C851E (NEL) North East Line 6 trains (36 cars) DT–Mp–Mi–Mi–Mp–DT 1500 V DC overhead catenary Alstom Urbalis 300 CBTC
Alstom Metropolis C851E (CCL) Circle Line 23 trains (69 cars) Mc1–Tc–Mc2 750 V DC third rail Alstom Urbalis 300 CBTC

For the North East Line, the 6 new trains will supplement the existing Alstom Metropolis C751A and Alstom Metropolis C751C trains when the 1.7km long extension from Punggol to Punggol Coast opens in Year 2023.

The trains draw power from a 1500 V DC overhead catenary. They are fully automated (ATO GoA 4) and capable of normal operation without 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.

The trains are manufactured and assembled in Alstom’s manufacturing facility in Santa Perpetua de Mogoda (near Barcelona, Spain), and progressively shipped to Singapore from 2021 (delayed from 2020). Thereafter, trains would undergo testing and commissioning before they are put into service when the extensions open.

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.
