Doubt it. The newer batch of DM3500s with the brake light are
likely going in to replace those from the 269x & early 27xx
series. Some of those from the 269x & early 27xx
series were reg-ed in 1997 & 1998, while the newer batches
(2793H and beyond) were reg-ed in 2000. That's at least 2 years'
diff of lifespan expiry. So they are likely pre-empting the need to
de-reg those earlier DM3500s, & using the later batch of
DM3500s to replace them.
& the KUBs are likely to
supplement the fleet as well.
Unlikely it would be full KUB fleet anytime soon, but i'm guessing
likely 60:40 or 70:30 ratio between DM3500s & KUBs once they
finish retrofitting the buses they need with the brake lights &
info boxes..
Most likely 48 ( or 50, if they bring 2790/2819) over dm3500 n
around 30 kub. Maybe kub will be put on 170X.
