In recent months, you would have notice an increase in an occurrence of the burning smell on the NS and EW platform. This is alleviated at elevated stations as it is an open ventilated station.
There must be a change of parts associated with the braking mechanism recently which had caused this. The smell did not occur at the platform in 2017 or earlier.
SMRT had clarify no asbestos are used for their braking mechanism. This bad smell will provide an undesirable working environment for the SMRT service ambassadors who spent most of their time on the elevated stations platform. The question is what cause this burning smell to surface and SMRT had not provided any concrete evidence to support their case.
