PN "93" class delveries

 
  SMKondinin Station Staff

Location: Adelaide Hills
PN in conjunction with UGL will commence trialling the "93" class on the main line during the last week of June.

Hand over of the first two units will take place on Friday -6th July. At this stage, the two "93" class locomotives will be worked to Spotswood per train No 4132 Saturday (07/07) between Morandoo - Chullora then 7SM5 Chullora to South Dynon; same day. These two new units will then be transferred to Spotswood on either Sunday (08/07) or Monday (09/07) for further fit out of equipment.

During the first couple of weeks, the two "93" class locomotives will only work between South Dynon - Chullora to allow them to settle in with their "in line fuel" tanktainers. Should be working the #MB4/#BM4 trains by the end of July.

The order of the "93" class will be extended, currently nine on order.

The introduction of the "93" class will see the remaining "AN" class locomotives tansferred to New South Wales.

As most would know 9301 and 2 are at Spotswood ATM for retrofitting cab stuff . They are supposed to be released on Friday and will be running back and forth to Sydney for a week to get the in line fueling sorted . After that the plan is Melbourne Brisbane services .
From what I read the next two come on line mid month and the last two of this batch towards the end of the month . There are plans to built three more early in the new year .
It will be interesting to see the final cab equipment specs and the updated computer software and screens . If what I'm reading is right these later C44ACis have updated inverters compared to 92s and TM cutouts are through software rather than physical switches . We hope the power reduction software is on the way and I suppose that would make them a Cv44ACi .

'We' or 'I'?

And why the need for variable horsepower? How often is it used on the NRs and how often has it been requested on new units from either builder since the NR?

Both and all the time .
Like we keep saying these trains have to be powered to climb the ruleing grades on the north south and east west and they all have 1:33 or 1:40 grades for some part . This means having more power than is needed a lot of the time and using it means burning more fuel dollars .
Often we depart Sydney going south and follow various tin cans so the pace is pretty slow , we are encouraged to put as many units off line as possible and run one or two flat out . Average speed is about the same but the fuel burn rate isn't . If the trailing units aren't NRs they can't be put off line or their power reduced on the move and its not always possible to stop go walkies and fiddle with engine control switches .
To even up fuel levels between units means working some harder than others and the only way to do that is to have control of each one from the front .
Think of it like this , Intermodal trains are different to bulk trains in that they generally run loaded both ways . A coal or wheat train has an empty leg and a fully loaded leg and the difference is considerable . Say for example you leave Pt Kembla with four 82s and 45 hoppers and bulk wants you back at Lithgow as soon as possible . 12000 Hp burns a lot of fuel and the trains don't handle as well with excessive horsepower . If they had the ability to be limited to 1 6 7 or 8 notch you can burn less fuel and set the power to suit the needs of the various locations on the fly .
For us the best example would be those long Perth Intermodal services up to 1800m and 5200 tonnes . It may take 4 NRs and 16000 Hp to get them going and up to speed but quite often just two will keep them going at the required speeds to run their tables . These longer trains if loaded evenly are great for momentum running and often don't need anything like rueling grade power to keep them stretched and at the required speed .
Fuel costs are a significant part of any rail operators bottom line - to the point wher more modern and fuel efficient units can be justified in budgets . The theory is that AC diesels pull more than DC units of about the same power and weight so if you use less of them running flat out more often you save fuel and money . There will still be times when ruleing grade power with AC units can be too much because its not like they can pull double what a DC unit can , I think the aim with these C44ACs is 200 t/unit more than NRs can so 3000T through loads for two units between Melbourne and Brisbane . The $64 question is can they run the tables with 8600 Hp .
First word so far is that two 93s want to pull at around 28 km/h with 1500T loads on 1:40 grades .
I think the first run of the 93s is on Saturday nigh out of Melbourne then back and forth to Sydney for a week .
Going to be interesting for people who've virtually lived in NRs since 1997 to see if the update C44ACs live up to expectations , time will tell .

If it was so handy why have no other locos been built with this feature? If it was all it was cracked up to be wouldn't the SCTs, LDPs, (insert other post 1990 diesel for intermodal) have it?

I believe it was part of the late Dash 8 software package and obviously optional in Dash 9s .
Maybe its not something EMD offered or was used as an alternative to locotrol which hasn't been used here AFAIK .

Greetings

Locomotives 9305 & 9306 will be released from UGL on Monday 16th July 2012 (being delivered out of sequence!). They will be hauled on train No 3NY3 ex Morandoo on Tuesday (17/07) to Sydney then forwarded to Spotswood to fit additional equipment.

Locomotives 9301 & 9302 will be working train No 7MS4 (South Dynon to Chullora via East Hills) Saturday 14th July returning on train No 1BM2 (Chullora to South Dynon) Monday 16th July.

"Junction box"


Yes, C44ACi with inline fuelling, and a few slightly newer features than the 92 that make them more suited to intermodal than the 92s.

Hi all

More 93 class has arrived today on the 3MB2(9608) Superfreighter from Brisbane with NR9-9306-9305-NR12 http://www.flickr.com/photos/Railpage/7595220228/in/photostream

3BM2 that was , passed it in the early hours of this morning on that trains opposite number with the other two .  
Retro fit mods appear to be ICE radio and fuel fillers more like NRs have . Wheretfkarwe screen is now down in the same place as NRs , four screens aimed at the driver if you include the ICE radio . 
Everything on/in these 93s is different and will take a bit of getting used to . Different brake controllers with no 70 kpa reduction detent . Screens and software nothing like -9 and not really like 92s have either .
They pull a little better than NRs on 1000/1100T per unit and stand up a bit better in dynamic brake mode in slippery conditions , would like manual sanding in dynamic like -9s have . 
They are very touchy loading up in dynamic and power up a bit faster than NRs too . Its different looking at KN readings rather than TM amps as well . I was told 92s die in the bum at about 90 km/h , these 93s seemed to keep pulling at least to 110 but don't feel quite as long legged as an NR at higher speeds .
In line fueling kept the fuel levels between 6900 and 7400 with no issues .
Pulling full section loads will tell the real story with these C44ACs

Both 9305 and 9306 are currently in road 2 at the LPC.  I understand they will be heading down to Spotswood tomorrow morning.

Slight change of plan. 9305 and 9306 just left the LPC behind NR12 and Dl50. Both the 93 class appeared to be powering. I assume they are headed to Spotswood.

Did you guys get both the hotplate and Microwave set up like the 92's or just the convection oven like the CF44's?

When last on 9302 , last week , it had the microwave cluttering up the desktop as originally built . So no the hot plate is said to be part of a later retrofit .
I think all that changed was Fcarwe screen refitted where NRs have it and Ice radio pole dancing behind the island control stand .
Also as previously mentioned the side fuel fillers are similar now to NRs , and should have the larger dry break couplings also like NRs have . Pretty sure northern coal and R&B still use the smaller DB couplings like 81s have .

In the fuel shed at Pt Waratah you can see both size guns for connecting to the std coupling or the slightly larger ones NRs have .
There used to be a step up adapter there as well and we use a different adapter in Sydney to connect a standard size Banlaw gun to the screw fitting on Victorian and South Australian engines .
