I start with Service 2 especially along Changi Rd,Geylang
Rd,Victoria St & New Bridge Rd.
Service 3 at Pasir Ris area,Narrow roads and fully packed during
school times and peak hours.
Service 7 Changi Rd,Orchard Rd Jams but overall still an average
services due to it's long timing schedules during off-peak
Service 9 Packed at Simei areas,Tampines and the short-Timing
schedules makes it even worse
Service 12 Bedok areas especially peak hours.
Service 14 Super-Cashcow service and almost had paxs
alighting/boarding at all other stops
Please add on.......
