Escalator Maintenance at SMRT Stations

Your Journey Matters – Edition 2 was published in October 2016 to update commuters on SMRT’s rail tranformation efforts to improve and renew the North-South and East-West Lines (NSEWL)- Singapore’s oldest, longest and most heavily used MRT lines.


On 7 January 2016, SMRT awarded OTIS Elevator Co. (S) Pte Ltd the contract to refurbish 233 escalators. These escalators are located in 42 stations along the NSEWL network. The $47.3 million contract will see work take place from August 2016 to August 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 such as Dual Speed Controller, Variable Speed Device and Balustrade Panels Securing Mechanism.

Site Survey Exercise

Since February 2016, SMRT and OTIS jointly commenced on the pre-start escalator and site survey exercise. The objective is to provide an assessment report on pre-existing conditions of each escalator, site and identify suitable holding areas for tools, equipment and components. This report will provide a comprehensive overview of the condition of all 233 escalators and assist in prioritising of refurbishment work required.

Key Challenges

This is the first escalator upgrading project to be carried out during service hours. Unlike other major upgrade projects such as re-signalling, re-sleepering, etc, the key challenge is to minimise inconvenience to commuters.

We will prioritise the refurbishment of each escalator based on a framework of principal considerations which include minimising where possible the impact to commuters and completing works in as short a time as possible. Commuters can look forward to more reliable and safer escalator rides as part of their daily journeys once all 233 escalators are fully refurbished.
