very clean compared to the filth in bay area, new york, chicago, and london subway trains. you’ll see occasional discoloring in ac vents in the ceiling but that’s due to condensation and dust coexisting together. they need to dry out the vents thoroughly and suck the shit out of those overhead vents with very powerful vacuum pumps, and the reason they are not doing that is because they need to put the car in service the following day after the usual interior cleaning. drying out vents will require at least 6.9 days.
do you see above? ceiling is so polished and clean.
Is there something wrong with the floor texture of the mrt based on the photo? I don't think it is clean.
