i ride a motorbike. i dun take mrt all that often but i sure am glad the defects were detected and steps are taken to have them rectified, covertly or otherwise. lesson learnt: compromising quality for cheaper initial price tag ended up costing more in maintenance, operational disruption, & future developmental progress, plus potentially endangers passengers & crew....but surely they knew the risks, so why then? to please the shareholders, maybe? who r these shareholders, bigwig fatcats who dun even take the mrt? why even "privatise" public transport in the first place?
