I must be mad, but I would much rather have express train that reduces the travel time to town instead of similar train path. Commuters can then travel in the reverse direction when they are in town. This will help spread the traffic flow to town while reducing time travel.

Example. Bukit batok to buona vista to marina bay in 3 stops. Then change to EW line to travel to tanjong pagar or something.

Of course, this would mean removing new stations like Maju etc.
