Two rail disruptions in October were electrical in nature, said the Land Transport Authority and SBS Transit in a joint statement released yesterday.
Aside from plans for all bus rides to be free during major rail disruptions, the Land Transport Authority (LTA) is also looking to make fare refunds easier.
Experts agreed that additional buses during an MRT disruption could have been better utilised to disperse the crowd to transport nodes.
Huge crowds gathered at taxi stands and bus stops as commuters waited for alternative forms of transport after MRT services were disrupted on Tuesday evening.
The North-South line will be suspended from 11:00am to 4:00pm for engineers to carry out further checks to determine the cause of the power trip.
Commuters on a Circle Line train were stranded briefly on Tuesday morning after a power failure disrupted rush hour services.
SMRT explained the causes of three recent disruptions on its train lines - two due to human error, and the other down to equipment failure.
Passengers commuting on the Circle Line experienced slower travel by 15 minutes after a power trip delayed normal operations.
