Service 73 should have been in Seletar Bus Package
Should have been under Seletar Bus Package
Too long interval. 25 minutes wait for the bus on non peak hour. The bus after that only a 4 minute wait. Does it even make sense??? Why not have both bus stagger 15 mins between each instead of having both coming together???
Service 159 or 88 should be a quicker choice if you’re heading to Ang Mo Kio from Toa Payoh
today i took a citaro on 73
