Last Saturday (Apr 10), a local trainspotter spotted the decommissioned refurbished Siemens C651 train EMU 217/218 awaiting to be scrapped at Tuas. This was similar to a previous spotting of a decommissioned C651 train at a Tuas scrapyard last September.
However, should the Siemens C651 Refurbishment Project be scrapped?
Siemens C651 Mid-Life Refurbishment Project
The Siemens C651 (SIE) trains are the second-generation of trains for the North-South Line (NSL) and East-West Line (EWL) and have been in passenger service since 1995. These trains were initially slated to undergo the Mid-Life Refurbishment Programme between 2016 to 2018.
New & Improved Train Systems
The refurbished C651 trains would feature new or refurbished train sub-systems, such as new air-conditioning systems, electric doors, brakes, propulsion systems, auxiliary power system, as well as improved interior and exterior changes.
The new IGBT-VVVF Permanent Magnet Synchronous Motors (PMSM) from Toshiba would have also replaced the original GTO-VVVF traction control from Siemens AG, as part of the Mid-Life Refurbishment Programme.
Singapore Rail Engineering (SRE)
Singapore Rail Engineering (SRE), a subsidiary of SMRT Corporation, was established in June 2014, providing in-house maintenance, repair and overhaul (MRO) services. SRE was appointed to refurbish the C651 trains in 2016 and had completed the refurbishment of EMU 227/228 in mid-2018, where it was spotted undergoing several tests along the mainline.
However, EMU 227/228 has never entered passenger service, and SMRT subsequently announced the discontinuation to refurbish the Siemens C651 fleet on 16 September 2018. This has led to a situation where a fully upgraded (albeit not fully tested) train becoming a liability.
Replacement with Additional Bombardier MOVIA trains
The Land Transport Authority (LTA) announced on 28 September 2020 that 40 additional Bombardier MOVIA trains were purchased to replace the existing 19 Siemens C651 (SIE) and 21 Kawasaki-Nippon Sharyo C751B (KNS) trains.
These new trains use the same design as the Bombardier MOVIA R151 trains and will arrive in batches starting from 2024.
This contract also covers the decommissioning of the existing SIE and KNS trains.

Continue Testing or Scrap?
With the cancellation of the refurbishment project, it can be implied that the funds for the prototype refurbished train to continue testing would have been reallocated and thus, the train would not be able to continue its tests for commissioning.
Was it a sensible decision then to task a 2-year-old subsidiary to perform in-house refurbishment works? This is in comparison to the first-generation Kawasaki Heavy Industries C151 (KHI) trains, which refurbishment project was out-sourced to Hyundai Rotem. The South Korean company had a massive portfolio with over 35-years of experience in rolling stock manufacturing.
Additionally, LTA has ownership of all rail assets and leases them to the operator under the NRFF. The transition to the NRFF may be another likely catalyst for the operator to make the unfortunate decision to scrap the train instead of increasing funding for the completion of the prototype train.
This has essentially made the train completed but redundant, which had cost the operator a hefty amount to have completed the initial design, testing and fitting of the refurbished train – which never saw the light at the end of the tunnel to serve passengers.
