For sure, the 3 express services (ie. 501, 511 & 512) will
be withdrawn after NEL starts. For 502, it is probably to be
amended to other places.
Maybe Svc 107 will be extended to Jln Kayu covering Svc 103 route.
(Svc 103 to be withdrawn), and Svc 100 to extend to Sengkang for
new link to Upp Aljunied and Aljunied area.
