I think the 56 bay Bedok Int now known is how it's derived
from.
Sv 7, 9, 14, 16, 17, 18, 25, 26, 30, 30e, 32, 33,
35, 38, 40, 60, 66, 69, 87, 168, 196, 197, 222, 225, 228, 229,
401, 854
30e & 401 can combi.
so 28 svs 
But since Sv 17, 18, 60, 69 dun terminate there, should be able
to free up 8 parking space for Sv 7, 9, 14, 25, 30, 66, 87, 168...
Oops not enough for 196, 197 riao
They can consider making 38, or even 25, 26 and 87 to loop at
Bedok Int instead of terminating there?
