Singapore Transport operator SMRT has awarded a $47.3 million MRT escalator refurbishment contract to Otis Singapore.

Under the terms of the deal, Otis will be tasked to fully refurbish and modernize 233 escalators at 42 train stations across the network. When completed, all 233 escalators will be upgraded with higher efficiency machines as well as new energy-saving controllers.

The project will be the first refurbishment and modernization effort for escalators on the North-South and East-West lines, Otis said in a release

These features allow the escalators to operate at different speeds and better cater to passenger traffic during different periods of the day.

The project is scheduled to start later in 2016 and due to be completion in 2021.
