Singapore Buses route 159

Service 159 is a trunk service plying between Sengkang Interchange and Toa Payoh Interchange, passing through Buangkok, Hougang Avenue 9, Ang Mo Kio Avenue 5, Ang Mo Kio MRT, Lorong Chuan, and Lorong 4 Toa Payoh.

Originally, Mercedes-Benz Citaros were deployed into that route in 2014. However, because a lot of JB-regged K230UBs buses from 27, 34, 64, 100 and 113 were shifted to the route 160 and 170, that is why the DM3500s plied on that route.
