I really miss the old Express 502 from Sengkang to Boon Lay and
also Express 501 from Hougang Central to Shenton Way.
But, sadly Express 501 was withdrawn due to the opening of the
North-East line
And Express 502 was cut back to Marina Centre also due to the
opening of the North-East Line.
Those were the days when there are buses travel on the CTE
tunnel.
Now all these City Direct services have started again... given
MRT is so crowded.
