Today's rare cameo, a Volvo B7RLE on 49X...

Sooner or later the outgoing Volvo & Leyland Olympians will be replace by kostly SDs

Seems like KMB is getting a new VDL DB330 dd unit from VDL (DAF) bus and coach with MCV bodywork (derived from PSV International/CDGE). Photo credits to 商用車大本營 HK-Trucks.
Maybe SMRT should get some of these too?

MCV bodied buses are quire expensive, look wat happened to SMB138Y...

This one 330hp?Wow in future mostly either SDs or 10.5/11m 2axles DDs running

HK Taxis are running on LPG, not CNG. It's not the same thing!

Nope. SMRT not getting this, but something else...

Actually I meant that even though most of the parts are made in other countries, it still bears a Sunlong badge. But since SBS Transit has bought so many Volvo buses I wonder why Volvo didn't offer SBS a hybrid yet. And I believe SBS had intended to obtain hybrids for testing in 2010, if it was a demo loaned to SBS it would already have been already returned and probably sold to some private operators already, but SBS is still holding on to the buses for some reason (same for RD6066L). This is what that really puzzles me.
Just like to point out to you that RD6066L was never sbst's to begin with.
All along it was a gift from THU to NTU. Sbst was only responsible for operating the bus during the YOG period, and a proposed trial on 179/199 which was not realized due to the cost of hydrogen fuel.
Why would it be parking in NTU otherwise?
Also, just to add to your points about hybrids, they are still not yet sustainable in climates which require air-conditioning as the engine still has to run to drive the a/c compressor and alternators. One of the main benefits of hybrids comes from the fact that they can shut off the engine while idling at bus stops or traffic lights and restart it again while moving off automatically. But the AC would be shut off as well if that is done here which makes no sense.

Oh, I thought that it belonged to SBST but parked there since it will undergo a conversion to full electric according to a newspaper report. It is very likely that the plan didn't materialize at all, wonder what will be the final fate of the bus since it is left at NTU without much maintenance.

Unless its a 11/11.5 or even 12m PTOs find it not practical use 2x DDs.10.5m the most can take 95 pax including standees.KUB can take almost 90.. -

Can't really compare directly, since LPG engines are not converted from Petrol or Diesel engines unlike CNG engines used here.
Also, LPG is cheap and gives longer range due to availability from China and 2x the density of CNG. Most importantly, it's not pegged to gasoil/crude prices unlike CNG here.

There is a reason, obvious reason why HK uses short DDs instead of just 12m SDs.

@bus stopping my Malaysian Uncle drive Taxi both tried using Cng and LPG,Long run not worth it cause of the fast wear n tear compared original petrol..
SMB128,narrow roads that have quite high passengers!Rather than using 10.5m 3 axles might as well use this...But A22 also got DD version that's what I'm talking about..

That is interesting, from what I understand Malaysia do not have any commercial LPG filling stations for cars. Only CNG (or as locals call it NGV) stations.

LPG change the tong gas,Some Naza Citra using it..tong stated LPG,Yes some taxis use NGV or Cng we call it..But more cabbies has since dismantle it since it's take long time for return of investment

Oh and btw, road conditions on popular svcs is not the only reason for introducing short variants of DDs in HK. It is also becoz of the travelling pattern and the fixture of most routes.
In Singapore, these DDs don't work AT ALL due to high turnover rates. In HK is different as short DDs allows more pax to be seated than standing (while carrying the same, if not more than the amount of paz a KUB can carry), and thus this is appropriate for most HK routes which either have many express sectors or sectors with long distances between stops.
Moreover, it also works great on cross-harbour svcs with less demand as it again allows more pax seated during the tunnel journey and still save till costs like an SD. 690 and 694 uses most of these during off-peak, alongside some SDs.
So the short DDs actually make a perfect alternative to a 12m DD. It doesn't mean that with road conditions then you will get short DDs, becoz it justs depends on how the company wants to use it, after all, and HK is doing quite a good job at this I can say.

Also to replace the about to retire Aircon Dennis Dragons for KMB

Recently in HK, about half of the short DDs become spare buses, as they have reached their lifespan of almost 18 years, going for their retirement. They don't have their own deployment route, therefore they operate at some important routes to serve as a ''打�車'' to take up more passengers. It is very good as these buses can help to maintain a high frequency of buses during peak hours.

Yes, for eg more and more short DDs are appearing on 798 either during off-peak or as emergency pullover when the Shatin loads are getting out of hand.

Its better to buy the 2 axles 10.5m DDs than the 3 axles 10.4m ones..Look obiang

I'm glad at least someone understands.
The pax turnover rate here for trunk services is unusually high, especially for buses plying through MRT stations due to pax who use them as feeder services.
As this will only worsen with more pax using the transit system, perhaps one way to overcome that would be to have trunks to bypass the stops near to MRT stations as the new Citydirect services has done.
This will allow for more efficient usage of DD with less passenger movement, as they now travel for longer distances.
