LTA Contract R151 (CR151) for the replacement of sixty-six (66) first-generation trains on the North South Line (NSL) and East West Line (EWL) was published on 13 April 2017. When awarded, the new trains will replace all 66 Kawasaki Heavy Industries C151 trains operating on both lines.

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 shift to a new rail financing framework – 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, SMRT announced its decision to replace all C151 trainsets with new trains, partially owing to LTA’s concerns with keeping the old trains running. Contract R151 for the replacement of these trains closed on 4 September 2017. Participating companies are:

  • Alstom Transport
  • Construcciones y Auxiliar de Ferrocarriles (CAF)
  • Hyundai Rotem
  • Bombardier Transportation
  • Kawasaki Heavy Industries / CRRC Qingdao Sifang

The contract is expected to be awarded in 2Q 2018, and will undergo rigorous testing before entering passenger service from 2022.

    I will think that Hyundai Rotem will bid CR151

    For the R151, I envisioned a design based on LTA’s livery. Maybe I have a prediction of who will build these trains, Maybe Siemens can win this bid so we can have a taste in its Inspiro platform for MRT Trains. I understand that it may be too mainstream to have Kawasaki and CSR Sifang build these trains.

      Hi Danish,
      Do not think that Siemens is going to bid for R151.
      ALSTOM, ROTEM, SIFANG/KHI and CAF should compete.
