I think it's troublesome to change trains at Changi Airport MRT station to go to Terminal1 and so on.
But, rather than extension of MRT East West line, I want rapid service from downtown to the airport.
Rapid service should stop at Joo Koon, Boon Lay, Jurong East, every station between Buona Vista and Bugis, Paya Lebar, Tanah Merah, and Changi Airport.
