New Aurizon 2700 class

 
  M636C Minister for Railways

I've been told a near-complete 2701 was rolled out into the sun to be inspected by senior Aurizon staff in late December. Not sure what the results of that inspection was, that's the last I've heard. No photos of that event have surfaced.

I was sent a photo from the event.
I've been told not to pass it on and not to say where it came from.

The locomotive body is complete and painted in the simplified yellow scheme.
There are no lights, no hand rails and the cowcatcher and front coupler are missing.

From the front it looks just like a 2300, of course.

At the rear, it looks like a larger radiator has been fitted extending to the rear where the toilet was located.

In the USA, 8-710ECO engines are often installed in GP40 cores with the same radiator as used by a 16-645E3, about 50% larger than that on a 2300. These require three cooling fans rather than two but my photo doesn't show any detail of the rear end.

Some drawings were seen showing a new toilet located at the rear of the engine in front of the radiator.
The new engine is four cylinders shorter (two cylinder spaces) than that of the 2300.

The photo shows some irregularity where the Aurizon symbol is located on the right side of the locomotive.

But basically it looks pretty much as you would expect.

I've heard that 2702 is a conversion from a 2170...

The current donor cores that I'm aware of are 2351, 2355, 2357, 2190D, 2182D...I'm not 100% sure if they'll be converted in that order. 2190D and 2182D have been sent down from Pring over the last couple of months. Pring is also where most of the surviving 2170s and 2170Fs have been hiding from Aurizon's accountants and will probably become the last hold-out for Aurizon's 16-cylinder Clydes in Queensland.

2255? I thought all the 2250s had been sold.

The 2300s and 2170s weren't fitted with a toilet. Only the 2300D's were and none of these are being converted.

Actually, there was one 2170 fitted with a toilet.  2208 from memory.

I thought it was 2209 that had the toilet but it is some time since I saw it.
I think 2275 had a toilet too, the only one of its class fitted.
I should have said "where a toilet would normally be located"
Converting a 2170 to an 8-710ECO would provide quite a lot of space where the extra eight cylinders were located.

If they are converting both types, doing one of each type to start off would help in finalising the design.

Definitely 2208D with the toilet. Prior to and after its conversion it was a long term North Queensland resident, mostly working on the Mt Isa and North Coast Lines due to its axle load. At the time of its conversion, apart from the 2800s, there were no Stuart (Townsville) based locomotives with toilets.

I have seen early concept plans that show the toilet cubicle placed between the engine and the compressor. The compressor is situated below the radiators.

The cubicle has a void built at the back of it, to allow room for a extended compressor drive shaft which is driver directly off the rear of the motor.

What is it with Queensland????

The QR Walkers DH's had the crew placed between the motor and radiator.
Now Progress rail wants to go back to the future with the 2700's and put the toilet occupant between the radiator and motor.

After close to two years of development and rebuilding, 2701 has broken cover at Redbank, reportedly sitting outside the plant in mostly finished condition.
  Sulla1 Chief Commissioner

2701 has broken cover and escaped Redbank with a test run to Grandchester early this morning. First visit onto the mainline as far as I know.
  Sulla1 Chief Commissioner

2701 was out for another test run today, this time with 2346D, the pair working west beyond Grandchester and across the Little Liverpool Range. Photos show the radiator compartment now extends all the way to the end of the frame.

All the above about 2701 is about correct. I can't say too much because I'm not supposed to say anything, but 2702 is very near completion (99%) and will be hitting traffic and testing not too far away. Tests so far, 2701, have been very encouraging and the type is looking great. Keep a look out for 2702 + 2701 out and about soonish, if all goes well. They're showing good promise. But I never said a word, you understand? You guys just keep watching, you're finding out for yourselves anyway.

And don't ask me questions because I don't come here much and I'm not permitted to say anything anyway. Cheers fellas, keep watching.
  Sulla1 Chief Commissioner

Thanks for the update Gwabegar, glad to hear the project is showing positive results - I've been a big fan of the Progress ECO rebuild program and it's potential for Aurizon's Clyde fleet for close to a decade.

I have been very surprised by just how secret squirrel the whole 2700 program has been. In North America the various ECO rebuilds have seen considerable publicity for the "green" strategies of their owner railroads - and I'd anticipated Aurizon hoping for some similar kudos amongst its peers and public.

I guess it's just a sign of the times and "commercial in confidence" that what should be a good news story is treated with the same levels of secrecy as the Manhattan Project. Hopefully Aurizon puts out a press release at some stage and gets some slaps on the back for giving the 2700s a go.

I spotted 2701 at Grandchester this morning with another 2300D class loco ( might have been 2366D but I was too far away to make out the number). Looked like another test run, no rolling stock in sight.

The 2700 class has doubled in size today - with 2702 breaking cover and doing a test run with 2701 on the Western Line.

On facebook someone mentioned these were AC traction can someone confirm or deny this?

That is incorrect.

They have independent control of each traction motor but the motors are DC.

There is more cables or hoses on the front , , could these be for electric train brakes ?   Does anyone know if the 2700's will get Distributed Power or similar ... ?

I can't see any surplus cables or hoses. There's the standard 1,2,3 & 4 pipes, and an MU Cable, where's the extra's you're referring to?
  Sulla1 Chief Commissioner

I believe the 2700s have DP fitted.

Although Aurizon are converting their coal wagons to ECP I don't think they have run a train with ECP yet.
But they continue to operate both diesel and electric coal trains with distributed power, presumably using radio links based on the Locotrol system used since 1972.

There is 3 of them.  On the nose of the loco directly above Aurizon logo there is what looks like a cover for a cable to plug in.  The other 2 are about 20cm lower on the corners of the nose.  They also look like cable receptacles even having what looks like a cable (or hose) coming from them and disappearing into the nose just below.   I'm just curious as to what they may be.  Smile

Ah I see what you mean now. I'd be very surprised if they were associated with an ECP setup, the ECP installations I've seen tend to have the intercar cable fitted beside the brake pipe hose.

There's no walkway or foot hold for that one above the logo, so the biomechanics to install whatever goes there would be interesting and probably not something that would be expected to occur regularly, but it appears it may be a carry-over from the 2300's, check out this photo, it has the socket too...

As for the two on the sides, it isn't a weirdly-placed step light is it?

Distributed Power on the 2700's sounds good.  All too often upgrade is only associated with more horsepower.  

I've seen a few coal trains on the Newlands system with 4100 + 4100 + 2200 consists , , the others with 3 X 4000's spread through the train.   It will be interesting to see where the 2700's will be used.

As for the air hoses here is a photo of a 2300 , I assume the 2700 has some duplication for ease of connection or maybe redundancy.

The 7 DFZ class locos in WA, converted from 2300 class, all had DPU equipment fitted.  While it was trialed, this feature was never used in revenue service.

Thats interesting !  Smile  So the 2700's with DP won't be a first for these old Clydes.   Watch out if Distributed Power is used in Qld, the DFZ's could find their way back home.

Three of the DFZ though have the raised cabs, which would make them too high for the Queensland loading gauge.
