SMRT Upgrades Older Trains on the North-South and East-West Lines

Improving the North-South and East-West Lines SMRT is making good progress in its multi-year, multi-project efforts to renew the NSEWL. This marks the biggest transformation of the Lines since they were built in the 1980s.

The C151 Kawasaki Heavy Industries (KHI) train entered service in 1987 while the C651 Siemens was introduced in 1994. Although introduced seven years later, SMRT is upgrading the 19 C651 Siemens trains first, as they have logged a higher number of train faults compared to the other train models. SMRT and Singapore Rail Engineering are finalising the proposed improvements for the train design and will proceed with upgrading work and testing of a prototype train in 2016.

When completed in 2018, the upgraded C651 Siemens trains will have new or refurbished train sub-systems such as air conditioning, electric doors, brakes and propulsion systems. These have been the primary causes of delays due to train faults. Upgraded trains will also have sensors that furnish the Train Captain and engineering staff with the train’s state of health, thus making it easier to operate and maintain the train. The upgrade will include a makeover that gives our passengers a new-look cabin.

The next series of trains due for an upgrade are the C151 KHI trains. We plan to equip  these 66 trains with the same advanced equipment as the soon-to-be upgraded C651 Siemens trains to achieve greater commonality for more efficient fleet management. The new lease of life from these upgrades will result in rejuvenated trains that will serve our passengers with much improved levels of reliability and ride comfort.
