  2. Fantastic reduction of travel time when compare to #518. What a huge difference with Tampines route remove. We need more bus services like this for ‘End of the World’ residents. Please consider a bus like this from Pasir Ris to Joon Koon or Boon Lay via PIE or ECP . At the moment with it takes 2 hours for those who are not living near the MRT stations to get to NTU.
