Alstom Metropolis C830 | SGTrains.com

The Alstom Metropolis C830 trains are the first generation of rolling stock for the Circle Line.

40 trains of three cars each were purchased and housed in Kim Chuan Depot and have been in passenger service since the line opened on 28 May 2009.

These trains receive power through its current collector shoes, electrified by the third-rail electrification system alongside the running rails.

These trains bear similarities to the first generation Alstom Metropolis C751A running on the North East Line and are the first MRT trains with a viewing space integrated with the emergency exit ramp.

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 830, which includes the supply of 40 new trains for the 30-station Circle Line (CCL), was awarded by the Land Transport Authority (LTA) to French train manufacturer Alstom Transport SA in December 2000.

As part of the turnkey contract awarded, Alstom is responsible for the overall project management and the supply for communications, electrical, signalling, train control and power systems for the CCL through its Axonis solution for a fully integrated metro system.

All 40 trains were built and assembled by the French manufacturer at their facility in Valenciennes, France.

The first trains arrived in Singapore from 2007 onwards, where it subsequently entered passenger service on 28 May 2009 with the Circle Line Stage 3.

Exterior

These trains sport a black livery and a red-colour strip throughout the whole train.

The design of the train is also curved, giving it a more streamlined look.

A yellow LED display at the top left corner of the train's head is used to indicate the train numbers.

These MRT trains were the first in Singapore to feature additional viewing space integrated with the emergency exit ramp, allowing passengers to view the tunnel while on board.

Interior

There are three colour schemes in the train cars, with each colour applied to one car of the train.

The colour of the seats uses a single shade of maroon, blue and green in the three different cars.

Modifications

Design of Hand Grips

Variations of the hand grips were found in selected C830 train cars.

These hand grips were removed when the handrails were modified.

Modification of Handrails

Handrails were modified as a trial by LTA to encourage more commuters to move towards the centre of the car.

The trial was conducted in train car 8042, and it has been rolled out to the rest of the C830 train cars following a sucessful trial.
