Random thoughts on DTL3 route changes / amendments:
Do comment and criticize. 
Geylang Bahru: It will defeat the purpose. Bus service along the
expressway is faster mode.
Kaki Bukit: Re-do everything, such as the bus stop reinstatement
to provide connectivity.
Bedok Reservoir: Within walking distance.
Tampines West: Within walking distance to Temasek Poly/Tampines
GreenTerrace. Resolved everything.
Tampines East: Within walking distance of any service. No need a
change.
