from Serangoon to Orchard can take CCL and transfer at Bishan.
zaobao says it takes 18 min to reach compared to 21 min taking NEL
and transferring at Dhoby. i suspect both ways take
about the same time and i dont believe can reach in 18
min because from Bishan to Orchard is already about 15 min. i
dont know how they calculate the Serangoon to Orchard one as the
press release only gave Buangkok to Toa Payoh and Bishan to
Serangoon as examples.
anyway from Serangoon to Orchard the fare will become
cheaper because of the CCL but pple can still choose the NEL route
and pay the same cheaper fare. in this way the CCL can actually
benefit pple who dont use it and who prefer the current
mrt routes. e.g. Hougang to Newton, because of the CCL
the fare becomes cheaper, but i think some will still prefer
to transfer once at Dhoby rather than transfer twice at Serangoon
and Bishan
buangkok to tpy got give bus example ma 
142 den NEL?
actually if pulled off well 142 NEL should be faster.
