The Land Transport Authority (LTA)’s Contract R151 (CR151) replacement of sixty-six (66) first-generation C151 trains on the North South Line (NSL) and East West Line (EWL) was awarded to Bombardier (Singapore) for ~S$1.2 billion on 25 July 2018. The R151 Contract also includes an option of long-term service support to the Train Operator (SMRT Corporation) for the new train fleet for their design life of 30 years. The cost of the 66 new trains is approximately $827 million, as per the base tender bid price. The tender was published on 13 April 2017.


Main Article: Kawasaki Heavy Industries C151

As the first-generation C151 trains were approaching the end of their lifespan, SMRT was exploring ways to overhaul these trains for continued service. In 2014, SMRT inked a deal with Japan’s Toshiba to replace all 66 trains with Permanent Magnet Synchronous Motors (PMSM), reducing power consumption by 30%, noise levels by 12 dB and being easier to maintain. This was part of a major engineering component replacement on all C151 trains expected to be completed by 2019.

However, in August 2016, the Land Transport Authority (LTA) and SMRT agreed to transition all existing rail lines to the New Rail Financing Framework (NRFF), in which the Government assumes responsibility for the expansion, replacement and refurbishment of all operating assets, including trains. Refurbishment works were halted as LTA reviewed the best course of action, despite SMRT already being committed to the installation of the new PMSM propulsion system.

A month later, in September 2016, the LTA announced its intention to replace all 66 first-generation C151 trains with brand-new ones, favouring the procurement of new trains over continuing to refurbish old trains. Contract R151 for the replacement of these trains closed on 4 September 2017, and was subsequently awarded to Bombardier in July 2018, who would supply Bombardier MOVIA trainsets under this contract.

The CR151 trains will be manufactured and assembled in Bombardier’s facility in Changchun, China before arriving in batches from 2021. The trains will then undergo a rigorous testing and commissioning process before they are put into passenger service from 2022.


The interior cabins of the train are designed to include more open spaces for parents with strollers, wheelchair users and commuters carrying their personal mobility devices (PMDs).

Tip-up seats in the train can be folded up during peak hours to create more room for passengers, without a reduction in the overall number of seats per train car.

The trains are designed to facilitate a more robust, efficient and effective predictive maintenance regime, with integrated condition-monitoring features and sensors that transmit data back to a server that can identify emerging faults for rectification before they occur. The trains are also equipped with a self-test system that automatically checks that the trains are fit for operation before daily service commences.

In addition, four CR151 trains will be fitted with an Automatic Track Inspection (ATI) System, which allows concurrent monitoring of the running rails, track equipment and sleepers during operations. The ATI System supplements existing track inspection activities to identify rail and trackside components that require maintenance in a more timely and efficient manner.

    Maybe CR151 can be white on the top with a green stripe (East West Line) below it, then followed by a red stripe (North South Line). The red stripe can also represent part of the SMRT color if it’s followed by yellow and finally black. I got the inspiration from KSF C151B and C151C, so CR151’s exterior should be the top half something of KSF C151B and bottom half should be something of KSF C151C in the future. Plus, The C151B part must be exactly be the same. That is the same for the C151C part. For the interior, it must look something like the previous trains, only it has a front of something like C951 since both of these trains are built by Bombardier and are named using “Bombardier MOVIA” as the starting words. This message is for Singapore Land Transport Authority only. Got it? Remember to tell Bombardier, the company which builds, C951 and CR151 the following interior and exterior above!

    Since Bombardier’s rail division will be accquired by Alstom, will we see some Alstom tech in CR151?

    Can change the front view from driver cabin into the view similar to Thomson-East Coast Line so that we can see the front view rather than driver cabin blocking the front view of the CR151 train
