Do you wonder why trains on the Circle Line extension ends its service at Stadium during off-peak hours?
During the peak hours, trains from Marina Bay will run the full line and end at HarbourFront to ensure an average of about 2.5-3 minutes frequency throughout most portions of the line between Promenade and HarbourFront. This will help to meet the high demand of the Circle Line experienced during the rush hours.
However, during off-peak hours where demand is relatively lower, the trains running on the Circle Line extension from Marina Bay will turn around at Stadium instead of running all the way to HarbourFront. This will help to reduce operating costs by allocating resources to meet the lower demand for the Circle Line extension.
The Circle Line extension trains are unable to turn around at Promenade as there are insufficient track crossings to allow a shuttle service only between Promenade and Marina Bay, thus the shuttle was designed to be between Marina Bay and Stadium.
As covered last week, the sixth stage of the Circle Line will finally close the gap between HarbourFront and Marina Bay, and this will eventually change service patterns across the Circle Line.
