TIBS service 182 happens to be the last to use the hybrid
system. When SBS first introduced the One-Man Operation (OMO) back
in the late 1970s, they did not convert the whole fleet of some
services to OMO (at that time it was using step fare, not distance
related fare). Part of these fleet still use conductors and so they
are called HYBRID services.
In 1982, the following services use the Hybrid system.
2, 74, 83, 132, 157, 160, 165, 184, 196, 198, 209,
