1980s:
Beginning (Top White Below Green/White)
- Top with OMO/TMO/Hybrid sign
- Number bottom left
- Schematic Routes bottom right
>>Only the OMO logo (and the fare required for flat fare
serivces)was displayed. I'm not very sure but I think the above was
for OMO services only. For TIBS, this was the format of their first
side desto. However, it was all red and the number was larger than
SBS's. Destination printed on top while schematic routes to the
left. Buses with conductors were all green, the number was big and
in the centre. Only the start/end points were printed; in English
above the number and in Chinese below it. Same for TIBS's front
desto but red in colour. CSS's desto was orange with black
font.
Later (Top White Below Green/White)
- Top with OMO/TMO/Hybrid sign
- Number big at the centre
- Destination at the top of number
- One Schematic Road below number
>>This type was implemented during the OTS era. The top
either displayed the OMO or OTS logo. Buses with conductors remain
unchanged. Only the start/end points were printed, no schematic
roads. Similar format for A/C services but in blue top with the
words AIRCON and red bottom. TIBS destos remain unchanged except
for the addition of the OMO-DRF logo at the top.
1990s
AC (Top Navy Blue Below Red/White), NAC (Top White Below
Green/White)
- Number at top left
- Destination at the top right (Fares at far right for feeder
svcs)
- Schematic Routes at the bottom
>>Sv. 170's desto (the sole survivor of the conductor era)
was all green. TIBS's destos also changed during this period;
similar to the ones seen on CSS buses today. Blue for AC, white for
NAC. Don't forget SBS's plastic side destos. For AC, number on the
left (white on blue). The words AIRCON was below it (blue on
white). To the left (white on red) were the destination (top)
followed by the schematic roads. For NAC, same format. Number was
red on white, the rest was white on green.
