TIB832Z and SMB3156A still perm 963?See always cameo other service leh..Ever since 5046 perm 963 always see these two buses running around.

832Z perm still seen on 963 only likes to cameo 187 alot

Yup they are still 963 perm.. 5046X swop perm sv with 1399D..

Just today it is seen on 187 should be TQ slot.
Originally posted by carbikebus:Engine strained not because of the Voith gearbox but more to restriction..You put ZF but restrict to 59kmh also no use mah.
Not true, for the A22s speed limited at 60kph, the engine runs at higher revs at 60kph with Voiths as compared to ZF. This is because the Voith only has 4 gears while the ZF has 6 gears, and typically on the ZF the 6th gear kicks in at around 55 to 60 kph, meaning that at 60kph, the engine will be running at lower speeds (ie at the lower end of the tachometer).
Therefore, in the above case where the bus runs at the speed limit of 60kph, the engine works harder with Voith as compared to ZFs, I would expect the ZF to have a fuel economy advantage over the Voith in this scenairo.

Fuel economy isnt that much either..Give a good gearbox tuning la..So far i have tried various buses with different gearbox..The drivers have to know when to decelerate when he feel that the 4th gear is strained at 60..You just have to learn the bus character..On paper is just a theory..Good drivers will know what is hold gear system is.
Originally posted by SMB3163D:But 301 and 927 were original full ZF MAN fleet LOL.. SMB3100K - SMB3103C (301) is ZF, SMB1570A - SMB1577G (927) also ZF
Except that SMB1582R and SMB1583M (voith) were appearing a lot on 927 before
Oops keep getting mixed up lol

Yes definitely driving skills and gear tuning matter, what irks me most is buses which go down from 6th to 5th because a driver kicks down, especially on Scanias. That way there isn't much fuel savings as compared to going to 6th and staying in the lower revs. But generally on the 6th gear at 60, a ZF will have better fuel economy than Voith, provided that the driver doesn't kick down to 5th.

Pro and cons...Its always SG buses have this problem..Other countries Voith A22s doesnt have any problem..Should raised to 63 kmh better..

woah..why the sudden transfer of buses? In exchange for higher capacity buses from KJ?

Wah expect mass transfer then,5 KJ A22s already in Amdep spotted by Mr Lemon1974.

All spotted inside Bulim on Saturday night by someone inside TT.

DDU training for AMDEP BCs?
Originally posted by SMB3163D:
Saw 1324U on 985 today and 1341U on 67 on Friday.. But had doubts cos both service also AMDEP half controlled
Spotted both SMB1324U and SMB1341U on 985 today

More likely for the rollout of the new DDUs as the training can be done in a classroom.

maybe replace 9551T since it is on that slot
