9316 and 9317 are painted and decaled at Broadmeadow. That makes 17, but there is another banana undercoated AC44 out the front of UGL near the fence. The number boards are masked over at the moment. It looks fresher than the other undercoated units that have been sitting around there for a while. That is the unloved GWU 010 in the pic above. There is at least 1 CRL still in Aurizon style paint in the shed behind the PH37, and another banana coloured unit behind the 93s. That is possibly old CRL 004?, not sure.

Cheers, Matt.

First unintentional load test  , due to similar trailing unit saying nope (with no alarms) I got one to pull a little over 1800t up Como and Loftus banks and whilst not quickly never seemed to be doing it tough . Came off the bridge powering up at 51 clicks and it settled down to 20-21 km/h and at most showed 500Kn on the load meter . Crested Sutho at 22 through Loftus at 58 and down to 24 over the top . Impressive to me anyway though I think in general use these units could do with higher gearing because they don't show anything like these numbers at higher speeds
BTW on the screens that unit was showing around 32-3400 hp on the grades so they obviously make more power than they can use with big loads at low speeds .

What's the gradient?

One in forty .
Did well and felt like it could have hauled more though at lower speeds . Fuel level was around 3100L so about 131T gross .
I think CEYs are doing 4500T (x3) up there and it's interesting to think they could do 5400 in dry conditions .
From memory these engines are rated at 1500T for 1:40s and 1700 in multiple per unit .
It probably doesn't sound like a lot from a Hunter Coal perspective but their grades are I think 1:80 so the engines loads would be  double or more , whatever it takes to haul 10,000T around . Guesses 3600/7200/10,800 ?

UGL brochure about their C44ACi units . What made me look was the continuous tractive effort of 525 Kn and starting 600 .
Is it possible to work out the load it would have had at the limit ? Is it as simple as 525 divide 500 times 1800 = 1890T ?
I'm interested to hear from Hunter drivers what any of these ACs do when you lose one on a ruleing grade , obviously they must stall but do they put up a good fight until they do ? I have heard a story of a crew losing a CEY on Cowan Bank and still making it , doesn't fit in with the earlier 92 LDP trial but no one was spraying water on the rails either .

With 3 x C44ACI locos I have lifted 4600 tonne from a standing start on a 1:40 grade. Not bad in my books but I'm sure you could do it with 12 good 48's too! These new locos certainly do have an impressive tractive effort but like every loco on the east coast, are limited by poor adhesion from light axle loads. The C44aci's arnt worth a cent in they wet.........

OT but I believe the C44ACHis do pretty well . With the others it depends on what you are comparing them to and what they will or won't lift . Puts you back in an 81 82 AN situation in the east and they have their all weather limts .
I wonder how three 82s go attempting the same thing .

The C40aci/C44ACHis do well because of the USDM traction motors they have and the weight they run at.
