SMRT tenders for 66 new 12m buses
-
even the extension of lifespan of Mk II and Scania's also need clearance from LTA through PTC.Originally posted by iveco:Apparently they needed special clearance from LTA to do so. Can anyone verify that?

Go Wikipedia and see.Originally posted by XiaoTaro:Firstly, BlueTec is the same thing as AdBlue Selective Catalytic Reduction.
And, OC500LE chassis do not currently support such engine/exhaust additives to ensure compliancy with EuroIV. The only OC500LE/LF with EuroIV is their CNG counterparts, not the diesel ones. (Please kindly correct me with a source if i am incorrect)
Also, SMRT may also be interested with OC500LFs, which is derived from the Citaro, it is a modular chassis, but different from OC500LE because it is true Low Floor, from the entrance all the way to the back of the vehicle(similar to Citaro). However, OC500LEs is not truely low floor as there is a step after the rear exit, similar to SBST's B10BLE CNGs.
Scania with the new exhaust system means the engines lags, buying a K310UB is better than buying a K230UB. -
there is no OC500RF, its O.500RF, as shown by examples in Australia.Originally posted by Scania N113CRB luver:Yea. OC500LE whereas the LE stands for Low Entry, whereas OC500LF stands for OC500, Low Floor. I only know about the OC500RF (raised floor), which is featured on SG's website of Mercedes Benz. -
Erh, think K270UB is better leis. 310bhp is like too powerful for a 12m SD bus. 310bhp is more suitable for the bendy buses.Originally posted by Scania:Go Wikipedia and see.
Scania with the new exhaust system means the engines lags, buying a K310UB is better than buying a K230UB.
270bhp already got 1250nm, better than the Volvo B7RLE, 290bhp producing 1200nm. Somemore the new 9-litre engine has only 5 cylinders. And although the engine lags, it doesn't use any additives. No additives = no extra costs . Then i ask you lah. You prefer an engine that lags but doesn't use any additional additives to be EuroIV, or an engine that requires additives to be EuroIV? I will choose the first option. Engine lags isn't really a big prob for city buses, unlike tourist coaches, which requires best engine performances. And also, it will help cash strap companies like SMRT to save extra costs on such additives.

OC500RF
Although wikipedia states that an OC500LE chassis running on diesel w/AdBlue will be avaliable in 2005, it has not yet been avaliable up to this date. Even the newer OC500LF series with diesel engines are still not Euro4/ AdBlue capable. -
Why are you all saying SMRT is cash strapped? Have you any idea how much profit they posted in FY2006 for the year ended 31 March? Its profit after tax is S$103 million!Originally posted by Scania N113CRB luver:And also, it will help cash strap companies like SMRT to save extra costs on such additives. -
Erh you forgot about the money spent on the retrofitting of the trains, which cost about 100million i guess? Cant remember the cost.Originally posted by The_Bus_Guide:Why are you all saying SMRT is cash strapped? Have you any idea how much profit they posted in FY2006 for the year ended 31 March?

And since you said SMRT isn't cash strapped, SMRT might buy Mercedes buses such as Citaros, OC500LE or the OC500LF. -
The refurbishment cost $142 million. The fact is that SMRT is not in the red so it is not cash strapped. Now, we are nearing the end of another financial year. Do you not think that SMRT has amassed a simlar profit margin by now, as they had for the past years? And it wasn't me who say this. It was extracted from their annual report which is conveniently available online.

And/or even Scania K230UB or K270UB or even K380EB or K124IBOriginally posted by Scania N113CRB luver:Erh you forgot about the money spent on the retrofitting of the trains, which cost about 100million i guess? Cant remember the cost.

lol The K124IB will be taken by SBST lah. DD mah.Originally posted by swee_heng:And/or even Scania K230UB or K270UB or even K380EB or K124IB -
Btw anyone seen before a Setra bus? Look at this! It has the biggest bus windows!http://suhirman.fotopic.net/p32627344.html

SMRt aren't cash-strapped. They are cheapskate.Originally posted by Scania N113CRB luver:And since you said SMRT isn't cash strapped, SMRT might buy Mercedes buses such as Citaros, OC500LE or the OC500LF. -
So much profits, and still raise fares? They sure know how to make money.Originally posted by The_Bus_Guide:The refurbishment cost $142 million.

iShift can be very useful especially if you drive trucks. i don't think that SMRT or SBST needs iShift since Sg does not have much hilly roads. iShift is basically for climbing up hills frm 1st gear and up to 10 maybe because 12 can run very fast
The bus will be crushed like the long milo tin can.
And [b]MitEvolution, Scania's semi-auto trans is OptiCruise i think, whereas Volvo's is iShift. Dont think semi-auto will be used in city buses, cause its 12-speed in both transmission. 6-speed is already like more than enough, let alone 12-speed.
12-SPEED! Keep on upshifting and downshifting all the time!
Yes, that's why Scania's slogan is "Just add Diesel!" . When using Scania's EGR technology, you dont need any additives for the engine to be EuroIV compliant, unlike Mercedes Benz, which uses BlueTec to be EuroIV. So without the use of any additives, extra cost are cut and money is saved.
I still think Scania's the best option. Reason? Its cheaper than Volvo and Merc. Its cheaper yet it lasts longer. Its cheaper yet it doesn't use any additives to be EuroIV. The only bad thing about the K230 is its minute engine. Produces only 230bhp, but a healthy 1050nm(or is it 1025nm? cant rmbr clearly. ) But still, the torque is enough to push a fully packed Scania. Also if introduced on SG roads, it will be the only city bus to have a 5 cylinder engine.

coach using ISHIFT too

Hello all,
Just to clear a few things up...
1. The Mercedes-Benz Citaro (O 530) is available with three Euro 4 engine options - the OM 906 hLA (6cyl, 6.374-litre, 286 PS), OM 457 hLA (6cyl, 11.967-litre, 299 PS or 354 PS), and the M 447 hLAG natural gas engine (6cyl, 11.967-litre, 252 PS or 326 PS). Of these engines, the OM 457 hLA and M 447 hLAG are also available on the OC 500 LE low-entry chassis. Mercedes-Benz has chosen to use Selective Catalytic Reduction to meet Euro 4 and Euro 5. The CNG engine has already been certified to emit less pollutants than specified in Euro 5.
2. There are two way to meet Euro 4 currently, both with their own pros and cons. Exhaust Gas Recirculation takes a portion of the exhaust gases and recirculates it back into the intake to cool combustion. Selective Catalytic Reduction uses a special reduction catalyst with an injection system which directs a spray of urea solution at the exhaust gases, neutralising nitrogen oxides - one of the main pollutants caused by diesel engines. EGR places a high load on an engine's cooling system whereas SCR requires seperate urea solution refilling facilities at the depot. Both systems add significant amount of extra weight to a bus.
3. Just because a 6-litre engine develops 280-odd horsepower doesn't mean it will outperform a 12-litre engine that develops less horsepower. A 12-litre engine relies on torque at low engine speeds to pull the vehicle along. With a higher displacement, a 12-litre engine also produces more power compared to a 6-litre engine at any given engine speed and therefore results in "effortless" performance. When driven properly, a 12-litre engine in a bus can actually consume less fuel than a 6-litre engine in the same bus.
Regards,
Dave -
ur headOriginally posted by Scania N113CRB luver:lol The K124IB will be taken by SBST lah. DD mah. Scania K124IB do have SD go & see WTS & some SD coaches they have SD K124IB , SJE are one of te examples -
yeah..Originally posted by ^tamago^:So much profits, and still raise fares? They sure know how to make money.
Things spoil also dun want to spend $$ to maintain, rather bother with crap like Credit card tie up or lucky draw -
K124IB standard aint a low floor chassis.Originally posted by swee_heng:ur head Scania K124IB do have SD go & see WTS & some SD coaches they have SD K124IB , SJE are one of te examples -
Rumours i heard>New Chinese low floor buses suspected using Euro IV Cummins engine,Another is J-Bus Low floor and last is the Scania K230UB

Yes! And I thought that should be the most basic thing to do.Originally posted by sbst275:yeah..

J-bus or Scania ! No chinese bus please, altho using my favourite engine brand Cummins, cause suspension is going to suck.Originally posted by carbikebus:Rumours i heard>New Chinese low floor buses suspected using Euro IV Cummins engine,Another is J-Bus Low floor and last is the Scania K230UB
Scania best liao! Full air suspension, no leaf springs! Also, Scania got my favourite wheels. 
btw where you heard this rumours from? -
they are gonna replace Nissans?
if i am not wrong there are 33 nissans now... -
No lah. They spend on the stupid interior EDS system for next bus stop, which are completely useless i think. Till now since its installed, i've never used it or look ed at it. And i bet other people also seldom use it.Originally posted by sbst275:yeah..
Things spoil also dun want to spend $$ to maintain, rather bother with crap like Credit card tie up or lucky draw I would rather them save up this money and spend it on something that's more practical. SMRT tends to spend money on things that are not practical at all(SMRT buses only, SMRT trains are better, spend money to refurbish trains). SBST are better off, instead of installing stupid EDS whatever sh*t, they save up $$$ and buy better and new buses. -
They can use bodywork with low floor wan wat , or modify lor. SMRT will buy K124IB or K380EB to show off to SBST's B9s as K380EB is powerfulOriginally posted by Scania:K124IB standard aint a low floor chassis.
