TIB 146 to TIB 250 were Hino HT228 Buses with Hino Body, non Air
Con.
TIB 251 to TIB 278 were Nissan Diesel U31SCN with Fuji body, non
Air Con.
TIB 279 and TIB 280 were the first 2 Air Con Nissan Diesel busse
with Fuji Body and Fuji Air Con, which is IBCU-050.
TIB 281 to TIB 310 were either Nissan Diesel U31SCN or R87, but if
I am not wrong, they are all R87, with Fuji body, Non Air Con. If
you have Bus Guide 1992, you can see the R87 on the cover, with
black headlights cover. The U31RCN from TIB318 to TIB336 has silver
rectangle cover.
TIB 311 to TIB 317 were the next 7 buses that TIBS bought with AC,
they are all Nissan Diesel U31SCN with Fuji Body and IBCU-050
AC.
TIB 318 to TIB 336 were Nissan Diesel U31SCN with Fuji Body, Non
Air Con.
TIB 337 to TIB 361 were Hino HT238 with Hino Body, non Air
Con.
TIB 380 to TIB 389 were Hino HT238K with Hino body and unknown AC.
Half of these buses were converted to non AC and then they were
transferred to SSB. These buses served on Service 950 if my memory
is correct.
TIB 390 was a Nissan Diesel U31SCN with Fuji Body and Fuji IBCU-050
AC.
All the AC buses (TIB279, TIB280, TIB 311 to TIB317 and TIB 390)
once served on Service 852. I can't remember which service was the
first to be PAC, so I will defer to SBST390's memory that Service
850 was the first.
When TIBS started buying MBO405 with Hispano body in bulk, and
Introducing them progressively from Nov 1994, TIBS started the
conversion of the original AC Nissan Diesel into Non AC. What they
did was simply disabled the AC controller and opened up the
windows. I'm not sure whether the AC on top was gutted out or
not.
After that, TIBS bought TIB391 to TIB 404, DAF SB220 with Hispano
Body (with the Service numbers on the left Hand Side of the LED
display), and TIB 405 to TIB 424, which was the same, just that the
LED display shows the service number on the right hand side. All
the DAF buses served on Service 950, 951 and 952 before being
converted to SSB buses.
