Transperth 1854 destroyed
-
G'day all,
It is with much sadness that I announce that Transperth Mercedes-Benz OC 500 LE CNG demonstrator TP.1854 has been destroyed in a fire in Perth today.
It was burnt beyond repair in a fire whilst on the road earlier today. The cause of the fire is so far unknown.
Following a short stint in service in Perth for evaluation, TP.1854 was shipped to Singapore for evaluation and then onto Malaysia for display. It was then shipped back to Australia where it underwent extensive modifications at Volgren in Melbourne and then rentered service in Perth.
Regards,

Transperth bus explodes in suburbs
"Mr Clementson said the fire started at the back of the bus where the motor was and it took four fire trucks about half an hour to extinguish the flames."
Oh dear, terrible news...Will our new OCs explode without warning too?
In hindsight, it might not be a bad idea to choose Scanias after all ... I think any chance of SBST ordering OCs in the future would have gone up in flames with this news.

As much as I would agree to the danger of fire, I cannot agree to the point of comparing different models and their ability to deal combustion in the wrong way.
I have seen MAN coaches went up in flames in Malaysia. This does not mean that they will stop buying MAN buses and coaches.
Any vehicle can go up in flames. It would be a stupid corporate decision not to buy a particular model just because one example caught fire. Same thing about the Citaro buses in London, that did not affect European sales right?
Just give it a wait, out of 1100 Scania K there will bound to be some which will meet an early end by fire.

Lol. Reminds me of 3833U

It depens on how the individual company takes care of the buses.Also to add on for Tibs/SMRT, there have been a number of Lances and bendies that caught fire and were scrapped. Eg. TIB675K, TIB900K, TIB936H, TIB1110S.

Not necessary. It may not be the single deciding factor, but it will influence potential buyers' evaluation, particularly so if the product is still new. Mcdonnell Douglas went bust because after the Turkish Airlines DC10 crash, the news scared many airlines into not choosing it.
And London did decide to get rid of all their bendy buses.

McDonnell Douglas did not go bust after the TK DC10 crash, it was the cancellation of SQ's MD11s over range deflicit(it couldn't fly Singapore to Paris Nonstop without severe fuel, cargo and weight penalties) that many other airlines followed and killed the MD11 programme, which MDD sunk a lot of capital into.

-
Quite a few.
TP.1610 was written off after it was destroyed in similar circumstances in Perth City.
TP.1297 was partially destroyed in Fremantle, again in similar circumstances, but was rebuilt with a new chassis and rear-end.
Most recently, TP.1877 was partially destroyed north of Perth. It is currently undergoing a complete rebuild.There have also been some fires inside bus depots but these were put out before any major damage was done.
The previous fires were caused by poor welding quality used in the design of the turbocharger oil supply line. This design fault was the subject of a massive Australia-wide recall shortly after the fire on 1610. The line was prone to rupture and when hot oil leaks onto a hot turbocharger, the inevitable is bound to occur. I suspect that the fires wouldn't have occured if this oil supply line was rerouted so that any leaking fluids would leak directly onto the road.

Sad news....Farewell to TP.1854.

DavePerhaps because of the old engine block design? If im not wrong, re routing the turbo oil supply will result in changing ur engine block design, because ur oil is fed from the engine via a gear pump attached to the engine casing. Hence you will notice why sometimes the turbo is placed only at a certain area and not anywhere on the engine(altho turbocharging pipe length that affects engine performance also play a role).
From the trend i noticed, seems like most turbo failure occured on the OM447 engine block. From a little info i saw from documentaries, different engine block and series are assembled on completely different plant lines. It is possible that the line that produces the OM447 block could have some problems resulting in the poor quality weld. -

London didnt withdraw all their bendies due to the fire alone. There are many other factors to look into.

I think it wont explode like this kind of situation becoz our OCs are bodied by Gemilang & not a CNG bus most probably.

Body doesn't matter, whether its CNG or not also doesn't matter IF its proven to be due to the malfunction of the oil pipe.

there are many factors that lead to a bus catching fire...one of it is like what Dave mentioned above...and since most of these fires occur on the OM447 engine platforms. let's hope that there's not much of a problem in the OM457 engine platform.
-
G'day all,
One thing to consider is the fact that the diesel OC 500 LEs are fitted with OM 457 hLA engines that are built and assembled in Europe whereas the CNG units are fitted with M 447 hLAG engines that are built and assembled in Brazil.

Quite a sad thing to know :(

Davei dun know much abt bus engines...but wad is he difference between these two?

ouch. Let's hope our 1H doesn't explode in lck..

The OM457hLA is a turbocharged and intercooled 11 967cc, 4 valves per cylinder diesel engine with 2 power options to choose from for the MB buses, altho initially there are 3 options but due to the new Euro V implementation one of the option was taken out. The specs are:
Before the Euro V implementation
- 252bhp
-299bhp
-354bhpAfter the euro V implementation the 252bhp unit was withdrawn.
The OM447hLAG is a turbocharged and intercooled 11 967cc, 2 valves per cylinder CNG fuelled engine. I not sure about its spec as i didnt study much abt it.

The M 447 hLAG comes in either 185kW (252hp) or 240kW (326hp). It is based on the highest-spec O 405 engine which was the OM 447 hLA. This engine actually uses the same engine management system as the OM 457 hLA and is therefore compatible with the 24V CAN system and Mercedes-Benz Star Diagnose software as used on standard issue current-model diesel buses.

if it does, wait LTA banned the whole batch of OCs...
