SBS Transit bus services A, B, and C originate from Bus
Interchange D located in Town D. Service A turns left from
Interchange D, while B and C turn right from Interchange D. A, B
and C are trunk loop services.
Service A's first stop from Interchange D is on Road G. Service
B also stops at that bus stop, but in the returning direction.
Services A and C do not meet at all except at Interchange D.
Service A will then go to a town north of Town D, then onto
Expressway E to another town further east, then onto Expressway F
to its looping point. At its last bus stop before leaving town D,
only Service A stops there.
Service B and C duplicate each other in opposite directions
(i.e. both services
duplicate each other on Road G, but C has already looped and is
heading back to Interchange D, while B is heading to its looping
point) on a section of Road G, to MRT station J, where both
services turn into Street K.
Service B will then turn right from Street K to Road H, then to
Road L to its looping point.
Service C will turn left on Road H, then return to Interchange
D.
