Buangkok Green (including me) people must be happy now with this service since 104 dosen’t serve the IMH area. Kind of expected this to come in as the main service is often packed during peak hours even with more buses add in. Hopefully the return version (from Serangoon to Punggol, especially evening peak) will also introduce soon.
