IMO, DTL won't kill 190 or 700... Each of them serves their own
purpose. 190 is to serve CCK area, 700 is to serve Pending/Petir
area, and 971E serves the inner areas of BPJ.
I am quite sure it won't kill the loading on 190. 971E is anyway
MRT parallel so that's okay.
For 700, I think it will definitely kill the loading. Look at
the routing. Majority people will switch, very few who have point
to point will not. All said and done DTL will affect the
loading on many services including 67, 171, 174, 700, 960 along
Bukit Timah stretch.
