Took the chance to have another nose around the Hutt shops this arvo....

All 5 of the EO's were within throwing distance of each other. ka9102 reports in the Wellington forum that 4 of these will be scrapped and the other donated to Ferrymead

30186 is now pretty much a stripped-out hulk sitting on blocks out the back, and probably destined for the gas torch as well.

Of most interest was a grimy loco with a tarp over the cab, but clear damage to the short hood. Looking at pictures elsewhere on here the damage I could see looked to match that of 7117 post-derailment, so my guess is that repairing it (and acquiring a replacement prime mover) and getting it back into service isnt too much of a priority. Parked end-on behind it looked to be one of the other two EF's down there.

Where's DQ 6376? Has it gone inside the workshops?

I couldnt see it, of the DAR for that matter. Thats not to say that it might've still been outside.

DFT 7199 is now resplendent in KR paint as well. Was heading up what I think was a late departing 220 (owing to some points issues in Wellington) behind the Twins but didnt seem to be under power.

Lucky 3196 was already on its way to Hutt when this happened at Taihape on Tuesday :)

That's interesting. Wonder if that wagon in front of the DSG started it first. :)

Thorough inspection noted that the coupler on the shunter broke off, causing the wagon to ended up like that.

5068 also has a bit of panel damage after meeting a tree at Ruatangata a couple of weeks ago

From what I've read elsewhere theres alot of train behind the shot, and the empty wagon didnt handle the momentum of 800-odd ton at all well, and the pressure forced the wagon up, snapping the coupler and into the shunter itself - as shown.


In other observations 1267 was coupled to 7008 this evening. No sign of 1200.

Edit: 1200 was hooked back up 1267 this morning

5195 was in fresh looking KiwiRail paint today. Not sure if its been running in it for a little while, it looked to new for that, or its just been released from Hutt. Leaves 5517 as the only DX running in Bumblebee now....

I haven't, and the only cues I have other than my own eyes and what I spot in Wellington is what I find online. The Wiki list (FWIW) has 5327 in KR paint; but as always Im happy to be proved wrong.

5195 was back in town again this morning, guessing it headed south on the ferry.

30105 is in loco row as well. Heading out to Hutt?

I understand that 4323 is also out there... parked in DA1471's old shelter from what I've heard

So an insight into KR's fleet thinking.... from Express

The first of the DFB class of locomotives is nearing the end of an overhaul at Hutt Workshops that involves restoring it to as near as possible to new condition.
DFB 7158 was selected as the prototype and has come through a challenging overhaul that’s lasted almost five months and cost approximately $900,000.
It is one of a group that was created from the DFT class. They were KiwiRail’s most modern diesel electric locomotives before the introduction of the new DL class and have been used for key traffic such as Lower North Island bulk milk.
“Now we have almost finished the prototype within budget, we should be able to improve on the time each overhaul takes,” says Mechanical Engineering General Manager Clive Cooper-Smith.
“Once we have fully tested the completed prototype, we will hand it back to our freight group for release back into service.
“We intend to monitor performance of the prototype to see if there are any other areas of improvement or feedback we can use as the full overhaul programme gets underway.
“Because we were looking for an as-new build, it was important that we controlled the quality to the highest standard.
“We had to build a locomotive that can deliver a 100,000km MBDF (Mean Distance Between Failure) level of performance.
“This means that everything needs to be done right. We used some of our most experienced fleet engineers to vet our work on the prototype and when they weren’t happy, we ripped it out and did it again.”
The overhaul programme was carried out by the staff of Group 15 within the Hutt Locomotive centre.
“I have been amazed at the way those guys have delivered,” says Fleet Logistics Manager Alastair Horsfield.
“Special recognition needs to go to Dragan Jaglicic, Garrett Cunningham and team leader Vishwa Dewan for the excellent results they have produced.
“We have also been well supported by other Hutt teams including light and heavy fabrication, components and our paint shop guys.”
Twelve DFTs became DFBs when Brightstar control systems were introduced between June 2006 and November 2007.
“Some locomotives in the DFT fleet have exceeded 2.5 million kilometres since original overhauls were done back in the mid-1990s,” says Clive Cooper-Smith.
“Overhauls were initially planned to start in the 2009/2010 financial year but were deferred pending the replacement of the fleet with the new DL class locomotives.
“However, the continuing development of KiwiRail’s plan to achieve financial sustainability showed that 12 DFT locomotives were still required for service out to 2020.
“Retaining the DFB sub class with its Brightstar control system was the logical choice.”
Alastair Horsfield says a specification for the overhaul of the locomotives was developed and the prototyping began in July 2012 when DFB7158 arrived at the workshop.
DFTs entered service as DFs
The DFT locomotives first entered service as the DF class (EMD model GL22MC) from 1979 to 1981.
There are two versions with subtle differences between them. Series 1 (20 units) and series 2 (10 units).
This class received its first major overhaul starting in 1984 and finishing in 1988. The average distance travelled in this time was 900,000-1,000,000km.
During 1992 a prototype locomotive was upgraded with a turbocharger and supporting systems to create the DFT class. The increased horsepower and performance warranted the fleet-wide upgrade of all DF class locomotives to DFT class.
The 29 DFT upgrades took place from June 1994 through to Feb 1997.
The DFT fleet has now aged well beyond the point at which the overhauls were due. The general fleet condition and reliability have steadily declined resulting in an increase in OPEX spend to maintain them in operation.

Full overhaul necessary
The arduous duty that the DFTs have performed has exposed some weaknesses in the structure of the engine mounting systems and control wiring that only a full overhaul could rectify, says Fleet Logistics Manager Alastair Horsfield.
“The primary objective for the overhaul programme is to restore the locomotive to an as-new condition within our budgetary limits,” he says.
“We have been able to completely rewire the locomotive while simplifying the layouts of the terminal boards and eliminating obsolete and superseded equipment and wiring.
“We have addressed several weakness in the original designs which led to maintenance issues as the fleet aged.
“Finally we were able to apply some of the latest innovations in components some of which we borrowed from the recent upgrades of the DXB locomotive class.”
Alastair Horsfield says the operator environment has not been overlooked.
Back in 2006 a new concept for cab layouts was developed when DFB7348 was recommissioned.
“We have used the same basic layout again but refined it further to improve on the original concept. The results have been fantastic, especially when you compare it to how the original DFT cabs look,” he says.



Those 12 DFB's are: 7010, 7200, 7348 (Maxx), 7158, 7160, 7186, 7239, 7267 (KiwiRail), 7173, 7213, 7241 (Tranz), and 7307 (Toll).

Two things - I understand Brightstar didnt exactly enhance the performance of those units, and given these are 'only' 30-odd years old arent they better long-term prospects than many of the DC's? 12 doesnt exactly sound like many to retain....

Anyone got any photos of the new refined cab layout?

Or someone like Kaiwhara tell us what the differences are since he's got a better chance of being inside it than most of us
