Alstom Metropolis C751A

The Alstom Metropolis C751A trains are the first generation rolling stock for the North East Line.

25 trains of six cars were purchased, they are housed in Sengkang Depot and have been in passenger service since the line opened on 20 June 2003.

These trains bear similarities to the first generation Alstom Metropolis C830 and its counterpart, the second generation Alstom Metropolis C751C, built during the same period.

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.

These trains receive power through the pantograph, electrified by the overhead catenary or overhead conductor rail systems, instead of the commonly-used current collector shoes against the third-rail electrification system.

This rolling stock model is currently undergoing a mid-life upgrade and refurbishment programme.

History

Contract 751A for the design and building of the trains was awarded by the Land Transport Authority (LTA) to French rolling stock manufacturer Alstom Transport SA in 1997.

A mock-up of the train was presented by LTA and Alstom in July 1999, allowing the public to provide feedback and evaluate the design and passenger features. LTA subsequently modified the seat colouring, floor carpeting and the design & layout of the grab poles.

The C751A trains entered passenger service on 20 June 2003 with the opening of the North East Line (NEL), achieving over 220,000 rides on the first day of operations.

Refurbishment and Upgrading Programme

In December 2018, the LTA awarded CRRC Nanjing Puzhen Co., Ltd. the contract valued at around S$116.7 million for the Mid-Life Upgrade of all 25 C751A trains. Facilitated by the LTA and SBS Transit, works are scheduled to begin in the first quarter of 2019 and are expected to complete by the third quarter of 2024.

The upgrade programme includes refurbishing and replacing interior fittings such as the seats, panels, and floorings. In addition, the programme consists of upgrading the air-conditioning, ventilation and passenger information systems.

The programme also includes installing a new condition monitoring system to monitor train performance for better facilitation of maintenance planning. Additionally, all mechanical and electrical systems of the train have undergone detailed inspections, with necessary repairs and replacements done.

The first upgraded train entered passenger service on 28 February 2022.
