New Aurizon 2700 class

 
  Sulla1 Chief Commissioner

A new locomotive class is coming to the Aurizon narrow gauge roster, with Progress Rail's Redbank Workshops currently developing the first prototypes for the mid-axle load 2700 class. Using 2300 class cores (Aurizon currently rosters 18 of the original 2300s) these locomotives will be entirely new-build from the frame up, and will likely be similar to, or the same as TasRail's PR22L TR class. Specifications are sketchy, word is a Caterpillar primemover is being used, possibly the TR's 3512 (although the EMD 8-710 would offer similar capabilities).

Considering this is a multi-million dollar project - potentially in excess of $60-million if all 18 2300s are rebuilt - it would appear Aurizon is investing in a long term commitment to maintain its Bulk Division operations on the remaining 15.75-tonne axle load grain and cattle lines in Queensland, which is news in itself.

Lets hope that soundproofing and ergonomics are improved on the rebuilt locos though I won't hold my breath

The talk is the project has apparently been suspended for some reason (price maybe?). Details have been so hard to find I'm not sure what's going on. It's possible Aurizon and Progress now have other plans rather than going down the rebuild path.

I personally would love to see some of these reported rebuilds happen.

I'm now hearing the EMD 8-710 will be used for this project and work is still under way using 2300 and 2470 frames. The use of the 710s would suggest the 2700s will be a narrow gauge EMD SD22ECO - possibly a GT38CU or GTL38CU model locally. Hopefully some officially released information will become available soon for what looks to be the most significant diesel rebuild program undertaken in Australia in the last decade.

Absolutely no reason to even try add AC equipment to these.

Locomotives will be emd710-8 (engine repower package from progress rail.

http://www.progressrail.com/en/rollingstock/locomotives/repowered/710eco.html

Locomotive will be lightened.

Toilet will not be on the rear due to excess stress they are putting on the frame, currently exploring options that having an 8 cyclinder, space will free up.
The cab forward will remain same.
Will have NREC dc indipendant axle control

Watch "NRE - Independent Axle Control SD40-4" on YouTube


https://youtu.be/6gdH7K9sVYA


Will be fitted with CCB2 eletronic brakes.

Cab will be the same but fitted with better sound insulation.

They are currently delayed as aurizon keeps changing the design.

The use of NRE’s N-Force system will be interesting. Independent Axle Control and N-Force have been dismal failures in New South Wales not living up to expectations reliability or perfomance wise.

Apparently it is pretty suscessful in the usa on sd40-2's plus Anything has to be better than nexsys / ztr system.

As someone who works with N-Force on a daily basis and has had a bit to do with the people who sell and engineer it; they’d have you believe that. From experience though, I beg to differ especially in the rain or on greasy rails. The 1100 class are fitted with N Force while the 1200 class have the additional Independent Axle Control fit out. Like the ZTR locos that have operated on the NSW network before them, neither have set records for performance or reliability.

One crucial thing to remember about aftermarket microprosser fitted locos is that the equipment probably does work well in heavyweight US domestic locomotives. Ours, especially narrow gauge QR Clyde’s weigh a lot less though.

From my experience in NSW, reliability on grades to me means genuine EMD electrical equipment or QES-III. N-Force and povopack NYAB CCB26 is a poor mans fit out. I hope the locos performance doesn’t end up reflectling that.

I'm wondering if some 2300D class locos have been taken out of service for this project as I have seen a few 2300 (no D) class locos on Acland and Cameby Downs coal trains recently (2338 & 2362 for example).

I understand a couple are in Redbank Shops but work on them has been somewhat sporadic and the concept changed?

Any word on an official model type yet? GT38LC-3 or something similar?

A little problem has been discovered when rebuilding these locomotives.

Copied from a safety advice.


"Chrysotile (white asbestos) has been detected in the top coupler / yoke pin wear liner of the draft pocket on locomotive 2351 (overhauled to 2702).  This locomotive is currently located at the PRS facility in Redbank"

"The wear liner is positioned above the coupler / yoke pin of the locomotive, inside the draft gear pocket."

"Further analysis is underway to determine whether other locomotive classes are affected (these may include; in QLD 2170, 2300, 2300D, 2470, and in WA DFZ.) Further communication will follow once the results of the analysis have been confirmed."

"The visual examination of the external part of the coupler is not considered a risk and should continue as part of normal      activities."  

Doesn't sound too serious and I would think a solution is at hand.

That's a total of 96 locomotives, all of which have been modified or rebuilt over the last two decades - seems odd this issue hasn't been detected earlier. There would be chaos, mostly west of Brisbane, if all of these locomotives are banned or withdrawn from service over this issue.

This could be a standard component sourced from the USA.
If the chrysotile is in bonded form, even on a wear plate, it might not be classified as dangerous in the USA.

If these items date back to the original constriction as 2400 class, they may have been perfectly acceptable according to the standards of the time. If no work was required on the component, its construction might not have been considered.

Why would you need an asbestos filled liner in draft gear? Surely there are better substitutes. Its not a hot area.

How many electrical cabinets have asbestos insulation on the old gear.

Any news of the 2700 class anyone ?

I asked the same question on another group and was told the project was suspended, cancelled, abandoned?

The asbestos scare with 2702 appears to have caused a few issues with the project and there are rumours the project has been suspended. The best I can determine at least two 2300 cores and a 2170 core are in the process of conversion.

The timing for the project probably hasn't helped either - throughout 2018 the halted intermodal sale, the collapse in cattle traffic, the long term viability of the Acland Mine and the loss of the GrainCorp contract has produced an environment where Aurizon must have been questioning the point of developing "new" 15.75-tonne locomotives. However, moving forward into 2019 - with Linfox potentially about to increase freight traffic on the Central Line and resume freight traffic on the Western Line, cattle traffic expected to make a significant comeback and Acland likely to continue expansion - the need for the 2700 project to support these freight tasks should suggest the project will continue.

I was also wondering , its mid March now.   I guess the 2700 project is going ahead OK compared to the GE Powerhauls , how many cobwebs must be inside those locos ?

Depends on how many spiders are around.
  Sulla1 Chief Commissioner

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.
