Boarded 085/086 c151 this afternoon (15/11). One SMRT technician got on board at KTB and the train had to terminate at AMK due to a technical fault.
I saw the technician, he kept looking and frowning at the part where the noise was coming from. When the train was turning in between KTB and YCK, the joints between two carriages was making lots of noise and the engine sounded funny.
Got off at BIS and saw quite a number of SMRT technicians all over the whole place.
One C751B at ADM had its brakes pulled so hard till the doors couldn't open. A SMRT technician was standing at the platform looking at the train.
