Forgot quite a lot of my SMRT regos, but for a start:
99 (1960Z) - Boon Lay Way (JE) to Clementi: So noisy, fanbelt problems plagued this bus so much. Scrreched when accelerating, moving fast, and anything it did.
While waiting at bus stop, saw Leyland cameo on 99.
184 (?????) - Clementi to Upper Bukit Timah Road (Bukit Timah Shopping Centre):
Bendy driver like got problem in his/her head. So unsteady.
67 (?????) - Upper Bukit Timah Road - CCK Int: Driver drives like brake, move, brake, move. Irritaing O405 driver. At least it was an O405 bus. Mercs and Volvos and Leylands, and Scanias seem to be my cup of tea.

927 (?????) - CCK Int - Zoo: The engine kept on making noise behind me.
927 (?????) - Zoo - CCK Int: I think it was the same bus. I sat further down in front, lucky thing was that now ride more pleasant.
MRT (3226 region) - CCK - Jurong East: Like Siemens train sounds. But SMRT plucked a lot of seats out. Why???
105 (936H) - JE Int - JE Central (2nd stop): The only pleasant bus in this entire trip. Reliable. Deniis Trident came into int when I queued up, MK IV PSV Soon Chow left after 105 turned out.
