Did you know that prior 2012, elevated stations do not have any ventilation fans installed at the platform level?
Between August 2009 and June 2012, half height platform screen doors were retrofitted onto all 36 elevated stations on the North-South and East-West Lines, enhancing commuters’ safety and reducing the incidence of track intrusions.
We covered this 2 weeks ago in our previous post, but in case you missed it:
Fun Fact Friday: Retrofitted Platform Barriers at Elevated Stations
After the installation of the platform screen doors, the platforms began to trap more heat resulting in higher temperatures – especially during the mid-afternoon periods. Thus, the Land Transport Authority introduced ventilation fans on the platforms in 2012 to allow wind to circulate around the stations.
Due to the variety of designs of the MRT stations, the LTA has introduced the “blades” and “jets” designs after assessing the suitability and effectiveness based on site conditions.
The “blades” design spins at a slow speed, but is able to circulate the wind around the stations. The “jets” design will generate wind from the component, but is only able to direct wind in a single direction.
