Whats all this Adblue stuff

That loco was puny compared to a big D57 hauling coal over the Blue Mountains. The black smoke from them was really notable.

Or coal on Fassifern Bank.

Not enough hills in the other states for a really generous whiff of sulphurous smoke. Imagine these coal hauling beasts in today's environment, They smelled a lot better though than a triple header diesel front and rear, as now at Ardglen. Stink is a better word, and I can't imagine the NOx, I'll leave Haakon to calculate the output from 20 thousand straining horses.

1950's, the Spirit of Progress to Sydney would be double headed with B Class diesels, and at Albury in the middle of the night when it was always freezing you changed to a NSW corridor train double headed with an impressive pair of steams. Don't know the class but they were fine machines. The track around Junee was always an impressive piece of laying guaranteed to wake people up.
 
Kim, EGR isn't always operative, and cannot satisfy new very low NOx emission legislation, hence the use of urea, in addition to EGR.

I think Kim linked it as there is a section on "scrubbing" to remove Nox that doesn't utilse ammonia?
 
SA has no railway grade as steep as those found in NSW, though they had some heavy locos for them.

EG, currently the city underground, the run down to the coast near Port Kembla from Moss Vale, the western line climbing over the Blue Mountains, and the mighty Ardglen bank at the Liverpool range on the Main North top the list. The last three have huge coal and wheat trains.

As well there are grade reducing spirals - the famous one on the Main South to Melbourne and another approaching the Qld border. Once there were also some extra steep mountain branch lines, eg Batlow, Dorrigo, Oberon, but these are now closed.

I think the locos that picked up the train from Albury in the 50s were C38s. These were the fastest of them all.

SA had some mountain engines built in 1925 that were the largest non-articulated engines ever built in Britain, by Armstrong Whitworth to American specifications. At least that's what their museum says. One in Port Adelaide museum. Never came this side of the border. Victoria never had such severe grades, the rise to Ballarat was hard on the locos but nothing more than a consistent grade. Might as well have been different countries, the engines were so different.
 
The SA 500 class, 2 cyls with a tractive effort 51,000 lbf (rebuilt to 59,000) were impressive, but the more numerous, heavier 3 cyl D57 a couple of years later could manage 65,000 lbf. The beasts were mechanically stoked like the later Garrets, which made for stupendous smoke columns. Garret crews preferred running tender first in tunnels to avoid the heat and smoke.

Which is why Renault has now steered away from "oiler" engines. Their new small capacity petrol engines appear to use diesel style solid crankcase bottom ends and turbocharging to achieve desireable power outputs from their low capacities, at the same time lowering emissions and fuel consumption. Their pursuit and development of electric production vehicles will also bear fruit as the whole world transitions to EV's.

Pretty much every manufacturer has done this
 
For most cars using Adblue, a fill of Ablue will last many months, perhaps more than a year, depending on mileage. A shortage in the short-term only is mainly going to be a problem for trucks and high km users.
 
And we're off! Stories in the press about adblue being the new toilet paper, trucks grinding to a halt, shortages of milk - time for a bit of price gouging for Christmas. Meantime Australia takes the modern economic rationalist approach of scouring the world for supplies of a product we once made and could still make in abundance here but where's the profit for the big players in that?
