New door rails, sensors, rollers and limit switches are installed to replace older parts that have been worn down through repeated use.
These 16 trains first came into operation in 2006 and are going through the second major overhaul works of their lifespans. These are works that the remaining newer six trains of the fleet, which have only been in service since 2019, will eventually go through.
Before the pandemic hit, the trains used to carry nearly 10,000 passengers per day and run from 5.00am to 2.30am daily. It is no surprise that the individual parts of the train get worn down due to regular use. According to the Engineering Management and Systems Planning team taking care of the trains, replacing these parts and others that have been damaged by passengers, is key to the reliability of the iconic Skytrains.
No free ride when it comes to maintenance
Replacing the major components of 16 trains is no easy task. The replacement work is arduous and extensive – from parts that we are familiar with such as doors, lights and floors, to those that are hidden away from sight, like brakes, batteries and traction motors.
