Commuter comfort Reduce ambient heat in North-South and East-West MRT lines

I am concerned about commuter comfort on the North-South and East-West MRT lines. As these lines operate largely on open tracks, the trains are frequently exposed to direct sunlight.

During the late morning and afternoon hours, sunlight streams through the windows, heating the cabin and making it uncomfortable for passengers, particularly those seated near the windows.
