Otis has been selected by SMRT Trains to service 446 escalators and 52 elevators on the North-South and East-West Lines (NSEWL) for five years. Starting from this year, Otis will examine, inspect and test the escalators and elevators on the NSEWL to ensure that they remain serviceable and safe for use. They will also conduct regular, ongoing maintenance on the escalators and elevators and replace parts when necessary.

In operation for over three decades, the NSEWL are the oldest and most heavily-utilised rail lines in Singapore's Mass Rapid Transit (MRT) network ? the two lines span 62 stations in total ? and are operated by SMRT Trains, Singapore's pioneer rail operator.
