The Bombardier Movia CR151 is the upcoming seventh generation electric multiple unit rolling stock to be introduced on the existing North South and East West lines of Singapore's Mass Rapid Transit (MRT) system, manufactured by Alstom (formerly Bombardier) under Contract R151. The new rolling stock will replace all of the C151s, C651s and C751Bs, which have been in service for at least 20 years. These new trains are part of the North South and East West lines' core systems upgrade and renewal programme.

106 six-car high-capacity Alstom trainsets comprising 636 cars will be delivered from 2022 onwards, entering service from 2022. The design of the trains will be completed in Germany, in coordination with Bombardier's Singapore team. The trains will be manufactured in Bombardier's Changchun facility in China.

With Alstom's agreement to acquire Bombardier's rail business in February 2020,[5] it is not known as to whether there will be any changes in specifications to the CR151 trains.

Operational history[]

In the 2010s, after the first refurbishment work of C151 trains, there are plans to replace the older C151 trains with newer ones. Eventually, after the second refurbishment work of C151 trains which includes the replacement of PMSM motors for the six MRT trains, plans to replace the older C151 trains came to fruition since January 2016. There are also plans to refurbish the C651 trains from January 2016. However, with the refurbishment works were terminated since September 2018, some of the C651 trains were taken out of service and sent for scrap with no refurbished C651 trains entered service.[6][7]

On 28 September 2020, it was announced that the Land Transport Authority has purchased 40 more CR151 trainsets at a cost of S$337.8 million, to replace all 66 first-generation C151, all 19 second-generation C651 and all 21 third-generation C751B trains, which has been in service for more than 20 years. In addition, there are many C151, C651 and C751B trains were also taken out of service and sent for scrap. These trains will be deployed from 2022 onwards.[8]

The tender for trains under the contract R151 was closed on 4 September 2017 with 5 bids. The LTA had shortlisted all of them and the tender results were published.[9]

Design and features[]

The CR151 trains are the second batch of trains that are not manufactured by Kawasaki and the past consortiums, after the C651 trains which were manufactured by Siemens.

It will feature a new livery of green and red stripes against a white background running around the cars, similar to the C151C. It is also the first train to feature a massive redesign over the other previous rolling stock, including the sixth rolling stock, C151C. That includes a more streamlined body design with a unique headlight placement and also the first batch of trains to come with bright white LED headlights over the conventional fluorescent yellow lights.

The trains also include several unique features, such as condition monitoring sensors and analytic systems to detect faults beforehand as well as an onboard self-test system that checks whether the train is fit for operation. In addition, four trains will also have an automatic track inspection system, consisting of cameras, lasers and sensors, to detect rail defects.

Furthermore, the trains would also have wider areas near the doors to aid the movement of passengers in and out of the train, and tip-up seats that cater to parents with prams, wheelchair users and people with personal mobility devices or foldable bicycles without reducing seat count.[11][12]

The trains will also utilise a Bombardier Mitrac propulsion and control system.[2]

It will be the second train type to feature LTA's new passenger information display, similar to those of the CT251 trains, during manufacturing process in which it will consists of a single, elongated LCD screen displaying the travel information, such as the upcoming stations the train will arrive at, door closing warnings and attractions nearby the station.

On 1 April 2019, Bombardier Transportation and the Land Transport Authority launched a mockup of the interior of the CR151 at the SG Mobility Gallery at LTA's office at Hampshire Road.[13] A poll was conducted to gather public opinion on the features of the train such as the livery, interior colour scheme, the tip-up seats and the Additional Passenger Media Display (APMD).[14]
