Absolutely nothing, they have no interest in the diesel era these wagons cover.

 

So logically they should also have no interest in doing the 91 then...

 

Oh - wait...............

For the shock and awe effect of seeing so many HAAs in one place the old Hornby one fits the bill just fine. I've only got 254 of them!

Thats almost a limited edition run of your very own !

Excellent news.

Excellent news. Hopefully a similar marketing strategy to "Accuscale" with multiple l running numbers  & 3 packs available from the launch . 

 

Like we did with the BBAs? We had 11 running numbers over 2 liveries with those.

 

We will be selling these with multiple numbers, check out our update on Sunday for more info and availability.

Totally the opposite of what Mr Kohler told me,

I think they just spread themselves too thin

Hi Danny

 

it’s the earlier British Rail owned wagons that ran from the late 60s up to the early 2000s.  They were TOPs coded HAA and later HBA and HDA.  Seen on MGRs across the country.

Are you thinking of the HHA?

 

as far as I’m aware, TOPS code HAA has only been used on the BR 4 wheel hopper.

 

Thank you both very much for the replies and the information. I really appreciate it. 

 

That explains why I was confused, with the TOPS codes been similar. I'm not surprised that Cavalex have opted to porduce these with a few different versions to model and they span 40+ years in most parts of the country on MGR workings. It's also beneficial that their will be the Hornby offering and new Cavalex offering, because for those potentially that can't afford the Cavalex models (no offence to anyone at Cavalex, I'm thinking of children and younger modellers and collectors), the Hornby models will be ideal and for those that want further variants, super detailed models etc then the Cavalex models will be ideal. 

 

Unfortunately, due to me not modelling BR days and not EWS in the early 2000s, I don't need any of these models, but I know that a new HAA has been long awaited by modellers and collectors, so I wish Cavalex a huge success with this one, as I am sure they will be and I will look forward to following the thread from the full announcement this Sunday to the arrival of the wagons. It's also brilliant that so many modellers and collectors have got their wish and I know many people will be really happy with this announcement. 

 

Thank you. 

 

Kind Regards, 

 

Danny.

Think you’ll strike gold with these ones lads, you deserve it too.

 

A true icon of ‘modern image’, looking forward to more details and eye candy in due course.

[Rich Papper]

Given that the last of new Hornby ones I've been slowly collecting for about 3 years arrived on Wednesday, I might be tempted to cry a bit.

 

Given the quality of other wagons from the Cavalex stable though I shall find a way to squeeze some in!

[66738]

Oh no!

[The Black Hat]

Saw this coming a few months ago from someone... but these should be stunning. Well done. Will most likely be getting some having just bought a full rake a few months ago! 

[rembrow]

For me , I will probably hold back on these. - I've already got a number of Hornby's 3 packs of both HAA and CDA wagons, enough to satisfy my usage and I'd have to think seriously before replacing. Hornby have successfully sold the triple packs over a long period of time, so for those who have already stocked up, it will be difficult to justify replacing. I'll wait to see a produced model so I can see how they will fit with my other versions.

If you dont like them making a HAA, why dont you still use the old Hornby bogie tank wagons instead of the new TEA?

 

The Hornby HAA has a few errors, even the new one they made was wrong. This is one wagon, just like the class 37, that has been waiting for the definitive model to be made for years.

That isn't a suitable comparison. The whole point of the Cavalex bogie tank is it is from the next generation of wagon from the 1980s and is a very different design - most noticeably with a continuous solebar instead of the sub frames of the Met Camm type of the late 1960s. Whereas the differences in the entire fleet of HAAs and HDAs are very minor apart from it not being clear if the model is to be original or rebodied. The pop rivetting is different - as is whether there are struts across the top of the wagon. 

 

Don't overlook the history of the MGRs is available https://hmrs.org.uk/merry-go-round-on-the-rails.html

 

And as to variants, I would have thought the CBA would have been of greater use than a CDA, being seen in far more of the UK and not in block trains but as part of the speedlink services. Full scale drawing in the HMRS MGR book, and I know David MS (the author) would share the electronic drawings with a manufacturer. https://paulbartlett.zenfolio.com/brcba

That’s why they’ve been producing HAAs of various qualities for over 30 years

Hmm...nah not really. They  produced one in the 1970s, retooled it a few years ago, but did half a job with the usual major gaffes. 

Thank goodness for new manufacturers who care about getting things right and to the absolute limit of current standards.

CBAs in block trains too Paul - the Tunstead - Margam was an early AB block working, from 68 IIRC.

 

Heres hoping they are on the list....

The original model has also seen various upgrades over its lifespan, current versions have a much improved tub with the better end profile and more internal detail.

Being devils advocate, I would imagine Cavalex will deliriously happy to sell even a small percentage of the "rubbish" version that Hornby have been flogging over the years!

Should look nice behind the new Heljan 47 when it comes out.

 

Or a 58. Heljan's model of this was one of their better ones. I wonder if it will prompt a re-run?

That is my plan, my 58s and pairs of 20s. Might even have to do a slow speed 47.

The iconic HAA in 4mm by Cavalex Models

During the 1960s to satisfy the growing demand for electricity, a construction programme of a new generation of power stations was undertaken, as part of the upgrade of the National Grid. Initially seven of the new generation 2,000 MW (2GW) power stations were to be built. These new power stations would require a continuous delivery of large quantities of coal to satisfy the appetite of these new electricity generating sites. To meet this rising demand for coal, a more efficient way of moving coal from colliery to power station was required. The existing fleet of wagons were no longer fit for purpose and so a new design of high capacity wagons was required for the future movement of coal. The Merry-go-Round concept was born.

The basic principle was for the train to be loaded at the colliery and unloaded at the power station without the need for stopping. It was envisaged that the train would carry some 2,000 tons of coal between colliery and power station.

What followed was the building of over 11,000 air-braked 32 ton coal hopper wagons which entered service that could operate a non-stop service from collieries to these new power stations. These new wagons were known as 32 AB HOP and latterly TOPS codes followed, with the standard 45 mph when loaded wagon, being coded HAA.

These iconic wagons saw continued service from the 1960s right up until withdrawal in 2009.

Cavalex HAA in OO

We are delighted to announce that in collaboration with KMS Railtech and Trains4U, we will be producing a newly tooled HAA family of hopper wagons in 4mm scale. The idea behind our HAA project first came about at a show last year (late 2019) when a customer of ours suggested this iconic wagon. From that point on we received more suggestions for this wagon and we started on the design early in 2020.

 

Numerous trips to Knottingley depot were made to ensure we captured the iconic wagon’s shape and features.

As a company we are very keen to embrace new technology and innovation to aid the development of our projects. Using a drone to photograph the inside of the HAA allowed us to capture all the fine details of the inside of the hopper to be included on our model.

Our thanks to DB Cargo West Yorkshire Area Management Team for their help with this project, we are extremely grateful.

 

The model is already significantly advanced and at the tooling stage of the process. Below are some 3D renders of the HAA design:

The wagon will incorporate the following features, as standard on a Cavalex Models’ product:

• Highly detailed underframe

• Zinc alloy chassis

• Easy conversion to P4/EM, with 26mm axles used as standard

• NEM coupling pockets, including NEM blanking plates for instanter use

• Sprung buffers

CDA

In the mid-1980s a plan was devised to replace the ageing fleet of vacuum braked wagons used for the Cornish china clay traffic. A replacement wagon type was sought and following the success of the HAA design for coal traffic it was decided to trial a converted HAA wagon for use with china clay. The trial wagon was re-coded to CDA and fitted with a roller sheet cover. An order was placed for a fleet of 124 new wagons which were to be built at Doncaster. The design was essentially the same as the HAA except for the roller sheet cover and ventilators at each end to aid discharge without the need to open the cover. A further 14 wagons were converted from HAA's to increase the fleet and also re-coded CDA.

Some of these wagons are still in service today.

 

Look out for next weekend’s update for further details on the Cavalex CDA variant.

Original bodied HAA and HCA

The original galvanised steel body version, as well as the lime carrying HCA, will follow soon after the initial releases of the HAA and CDA.

Good price and a good selection of options, time to start saving for a few sets from each shop.

Hi,

 

Could someone help me please.

Which versions of the HAA would have been running in the late 70s to 80s.

Would it have been the railfreight red version on this batch or the original version on the following batch.

I remember living in a house when I was younger adjecent to the wcml and you could feel the floor vibrating from them.

Good evening Garry,

 

The original body version would be suitable for the period that you are modelling.

 

Hope that helps.
