Confirmed it will be TTS. Who else? I suspect it could be the express feeder version of 861. Anyway, it seems Yishun and Tengah keep getting new services and always TTS. I know, I know. Because Yishun-Sembawang package and Bulim package under them. Anyway, I feel Bulim package might get adjusted because too many services already. I honestly feel Clementi services like 96,282,284,285 can go back to Clementi package since Bulim now got Tengah, Bukit Batok, Jurong East under their care.
Yes, 96 either extend to J East or together with Clementi feeders better go Clementi package but temporary Ulu Pandan purview.506 should bundle up with Bulim.
801 & 825 go Seletar better, 851,851e and 852 transfer to Mandai.963,963e give back to SMRT Woodlands with 962 under Mandai.
SBS Transhit or Toilet Transit?
