Addressing causes of major

• Communications-based Train
Control System (CBTC) will be
operational in 2017.
• Power assets renewal takes
place since 2016.
• Strengthening engineering
and maintenance
competencies to improve rail
reliability.
Cognizant of the impact that long duration delays have on the commuting public, SMRT is focused on further
reducing the incidences of delays that last more than 30 minutes.

Improved design for better reliability:
• The bracket spacing is decreased to reduce the chance of power
rail sagging
• An improved ‘claw’ design so that power rails are better secured
onto the insulator
• The bolted Mid-Point Anchor design will be used as compared to
the previous unsecured “drop-pin” type
New safety element:
• New inspection cover is introduced at the location of the
insulator for checking of the claw.

11. 11
Progressive Trials
• After extensive trials during engineering hours, limited trials during
service hours began on 28 March 2017.
• The deliberate and progressive roll out plan aims to operationalise
the new signalling system on the NSL with minimum inconvenience
to commuters.
• The progressive roll out allows SMRT to address any issues
immediately.
Improvements to service
• More reliable, advanced technology that allows trains to run closer
together.
• It increases the network’s capacity. With more trains, commuters
can look forward to shorter waiting times at stations.
New Signalling System

12. 12
New Trains
• 45 new trains for the NSEWL have arrived in Singapore and are undergoing
extensive tests.
• Another 12 trains are due to arrive by 2019.
• The 57 new trains will add to NSEWL’s existing fleet of 141 trains, bringing
the total fleet strength to 198 trains.
• The new trains have been progressively introduced for passenger service
on the new signalling system from 16 April.
• With more trains, commuters can expect shorter waiting times at stations.
Midlife Upgrade of Trains
• All 19 Siemens trains are being put through a mid-life upgrade.
• Improvements to passenger comfort and trains’ performance for the
second half of the trains’ lifespan.
• Refurbished trains are expected to be progressively rolled out for
passenger service by 2017.

Escalator Refurbishment
• Refurbish 233 escalators at 42 stations along the
NSEWL network. Works began in August 2016,
and is scheduled for completion by 2021.
• The two main objectives are to replace ageing
worn out parts such as traction machines,
handrail drive, lubrication system and safety
switches, and to add new safety features.
Station Facilities Upgrade

East-West Line
• The four new stations – Gul Circle, Tuas Cresent, Tuas West
Road and Tuas Link – are being prepared for operations by
2Q 2017.
Bukit Panjang LRT
• LTA plans to renew the BPLRT, including upgrading of existing
infrastructure and new LRT Trains.
