Bus Service 138M provides a direct connection from Ang Mo Kio Bus Interchange to Ang Mo Kio Polyclinic. It only operates on Weekdays & Saturdays, except Public Holidays, with operating hours matching that of the Polyclinic.

From Ang Mo Kio Interchange, the route plies non-stop to Ang Mo Kio Avenue 6, calling at the bus stop that is nearest to Ang Mo Kio Polyclinic. This allows polyclinic visitors from Ang Mo Kio Int to reach the polyclinic without having to cross the road, unlike existing bus services such as 86 & 138. Ang Mo Kio Avenue 6 is also affected by ongoing North-South Corridor construction works.

After Ang Mo Kio Polyclinic, the route is identical to parent Service 138, calling at all en route bus stops.

Operator Initiative

This bus service could be an initiative by the incumbent operator—SBS Transit—as part of its second tendered package term for the Seletar Bus Package (Contract PT219), which commences on 16 March 2025.

This is suggested by the absence of the Land Transport Authority logo on the operator’s publicity poster, in contrast to other new bus services introduced under the Bus Contracting Model. Additionally, this approach is similar to Peak Period Shuttle Bus Services LCS1 and LCS2, which were introduced in 2023.
