Use of PN 92 Class in ECP Coal Trains

 
  M636C Minister for Railways

Bradken have recently delivered at least 148 new NHIH class wagons (97374 was the highest number I saw) and there are two rakes of these running, one being Rake 20.

The locomotives changed between Friday 11 and Saturday 12, but 9206 and 9214 were in use.

Both of these have what appears to be a "through" ECP cable running down the air tank side.

The cable runs around the headstock on the rear but isn't visible in my photos at the front end.

I assume that the additional trains have stretched the number of ECP fitted locomotives (only TT class in coal service, but 93 class I believe are also fitted). It doesn't matter as long as there is a through cable and a fitted lead locomotive.

But since Intermodal are unlikely to use ECP in the near future, swapping 92 class for 93 class would give coal more ECP fitted units.

True but I believe the main issue is 92 class are set to full fuel load and weigh 139 tonne so best used on hunter coal for now.

The ECP cable is simply a "run-around" set up as 92 class are not fitted for ECP.

Units 19 and 20 are NHIH wagons, these replaced 2 of the old rakes that were scrapped, NHQH rings a bell. I am told the bogies under the NHIH are off the old wagons. We have no extra rakes.
The 92's were fitted with through ECP cables while they were in receiving the brake up grades as part of the investigation into the brake system failure of 9211. I did hear mention recently of 92's being fitted with ECP equipment, but I am yet to see anything solid.
If I am around a 92 anytime soon I will take a photo of where the cable goes through the pilot on the front of the loco. From memory it is on the 2nd persons side.

The builders plates show the three weights so it is probably just a matter of setting the fuel system to 7400 litres. The earliest 92 class were said to be at least two tonnes heavier than 139 tonnes full, however, so lighter items from later units might have to be fitted to get the weight down. Refitting with permanent ECP cables, even just pass through (as now) would be easier.

I am sure I read somewhere on here a post by BDA saying 93's will be going to coal to replace the CF's, some have already been returned to CFCLA.

For at least a couple of weeks, there has been an NHBH (100 tonne gross) set getting around behind 3 TTs. Not using ECP there. This must be helping to relieve those 82s that have been on ore trains etc.

93s and I think 92s have a key locked three position switch that sets the three maximum fuel levels . I'm told it has to be run past the regulators before any of them can use the two higher fuel levels , as mentioned in the past NR rebuilds were going to be reclassified as NREs until it was discovered money was involved ...
The only ECP equipt units we see are the NR repowers with DP and ECP , they have the extra screen on the drivers side and usually cable tie locked circuit breakers to power them up .

That is Unit 36, has 72 NHBH wagons. It has been doing the Stratford for about 2 weeks now. It is a very quick train when compared to having 2 82's on it.

There were 120 NHQH wagons (or so we think) but there were 400 NHPH of roughly the same design.
I think there were RHFH (?) wagons in pairs to the same design.

Why would they replace only the NHQH wagons?

These would be the first "Batwing" hoppers to be replaced as a class.

On reflection I may have confused the in line fuel connectors on 93 class for ECP, although they are nothing like eachother.

The bogies on the NHPH and NHQH are of two different types. Some have Goninan fabricated bogies, the rest have cast Barber or similar trucks. The cast ones are quite flat along the top. The bogies on the new NHIH have a slight downward bend in the top section and are cross braced. Also the holes in the side frames are a different shape to the old ones. The NHIH bogies are coded ECA. 0115 and 0193 are two numbers I have pics of. The have the BK logo cast on. They are all nicely painted, however the axle boxes look old and weathered, and the dirty wheels show different amounts of wear on brand new wagons.

I would guess that the new wagons have wheelsets from the old fabricated bogies. I haven't taken much notice of the mix on the NHQ/PH wagon sets lately, but I do remember seeing some fabricated ones in service a week or two ago.

Cheers, Matt.

PS, good to see the NHIHs haven't stood at Carrington long enough yet to be painted by the local volunteers.

Yep, that should read 3 82's. My bad typing it on my phone..........

As I recall, all NHPH were supposed to have the fabricated bogies but the earliest examples were unable to stay on the track so cast three piece bogies were substituted. The design was fixed and the later NHPHs kept the fabricated bogies, but the later NHQH wagons were built with three piece bogies.

But regardless of the bogie type, nothing to do with the bogies would require scrapping of the body.

These have been into Varley for crack detection, and I guess around 148 at least were too cracked to go on.

The photos I have of the NHIH bogies do indeed show what look like used wheelsets, with noticeably mismatched bearing cap types, much like the NHPH bogies in earlier photos.

These were built from 1996 until 1998 (with some of that time no doubt spent replacing bogies).

Sixteen years isn't much for a stainless steel wagon.

Is ECP fitted rolling stock distinguished in any way from unfitted stock?

Such as a special waggon code?

Such as a special livery?

The ECP wagons have additional electronics control boxes at the brake gear end, often marked with the manufacturer's name and model number. There is the cable and connectors usually near the air pipes at each end of the car.

The codes of ECP wagons are different but there is no special letter or indication in the code.

All Aurizon Hunter Valley Coal hoppers are fitted; QHAH, QHBH and the elusive QHCH which don't appear to have been used.

All Xstrata coal hoppers PHYH, PHEH (four unit) and PHWH (twin unit) have ECP. The PHYH operated with Westinghouse when new.

PN wagons of NHCH, NHDH and NHIH (four unit) and RHDH (two unit) are ECP equipped.

All PN Queensland coal hoppers are ECP fitted.

All FMG Ore Wagons are ECP fitted.

* What has happened to the Bomb Bay Fleet?  Eg NHFF/SH/JF/KF/FH.  Are they all still in service or have some been scrapped? I assume there is still a set in SA

* Are all the original 120T Batwings NHRH and variants still in service?

* The majority of Hunter coal fleet are Chinese hoppers now?

Whilst I can't answer your other questions, Southern Coal still uses an almost uniform fleet of bomb bay hoppers (aside from a rake of NHHF's which seems to pop up every now and then). These hoppers are still used to Stratford on the North Coast. On my last visit to the northwest (probably 12 months ago now), they were still being used with 82 Class to some mines. The new 120t hoppers might have replaced them since then.

AFAIK 93s don't have any ECP or DP gear fitted , Intermodal doesn't have a use for either so why pay for them .

On the coal hoppers with fabricated bogies, used up the Mountains, I noticed new vertical welds, painted white, in certain areas of what are probably the equivalent to a side frame. Perhaps these have been through Varleys for crack detection and repair?

Are the 120T gross hoppers from Stratford fully loaded ? If so that's 30 TAL on the lower NCR .

The NHFF/SH/JF/KF/FH types are 100t gross mass.These are run to Stratford.


120t gross wagons run to Gunnedah but limited to 100t gross mass with limits on loads per bogie as well as the overall mass.

These bogies have been the subject of crack checking and repair for many years.

They must be worth the effort, since they are largely still in service.

Many are seen with white paint along the lower edge of the frame.

Without wishing to be pedantic, none of these wagons are 'packs'. They are 2 and 4 'unit' wagons. Packs applies only to articulated wagons.

I presume you mean the wagons that share a bogie with their "partner" wagon, such as some intermodal wagons?

Regardless, "2-pack" "4-pack" etc is the term used in a lot of prominent railway magazines too, so at least it is a phrasing that most people here will understand.
