HS4000 Kestrel

This is an old project that has had a 40 year gestation period.
When I was a lad in the late 60s and early 70s this was the one engine that eluded me and then was shipped off to Russia so that was that.
When I started in O gauge in the mid 70s, I promised my self I would build a model of the said loco, which would have to be scratch built as no kit existed and doesn't to this day.
My intention was to built it from brass and to this end in 1978 I purchased a spare brass class 47 body from DJ Parkins for the princely sum of £12. This was hacked about (which I still have.) A start was also made on the cabs.(see photos)
The cab roofs put a stop to progress and the need to create all the roof details.
To cut a long story short it got put on to do shelf as other projects took precedent.
Coming upto date about four years ago as technics had improved namely 3d printing and drawing packages.

A member of my local club had become very proficent at 3d printing and agreed to draw and print the cabs.In the event he did the 3d drawings and then these were printed by shapeways.

I drew up plans to have all the roof details etched.Unfortunately the plans to etch the roof details didn't come to anything.
However the 3d printing was completed and was the spur to resurrect the project.

A review of how I could get this loco completed led me to build the main body and roof details from plasikard.

Progress is as follows :

Main body is wood with plasikard laminates to create three laminates.

The roof is based on formers with stringers to form the basic shape. This was then sanded down and a 10 thou skin stuck down.

I had acquired two abc motors chassis from a previous 47 which will be used to power the loco.

Also acquired over the years are some up graded class 47 bogie kits that i need to find. In the attic stash away.

As you may or not be aware the orginal bogies were exchanged for class 47 bogies later in its career .

I think thats enough for now.

Excellent project and posts to boot, thank you for posting.

If you had not said I would bever have thought of wood as the structural basis of the body.

regards, Graham

Thank you Graham , I cant take credit for that it comes from Steve Hoather who has written up his methods in the Gauge O Gazette and a recent you tube video a evening with available through their media page or just do a you tube search.
Incidentally i purchased the correct paint colours many years ago hopefully as never opened should be aright. Transfers were also purchased from Fox at the same time just a matter of thinking were i put them probably with the bogie frames.

Hi All
I am trying to identify the wording on the work plates attached to doors of the Kestrel. I can identify the top line as Brush second line as Hawker Siddeley and bottom two corners as No711 and 1967.However the third line defeats me. I attach two photos of the only ones I can find that show the work plates although these arent very clear. The originals can be viewed by searching flicker or Facebook, Derby Works Open Day 1968.

Any help or suggestions greatly appreciated.Derby 1.pngkest.png

Hello Andrew,

sorry I can't help you with the third line, but could it be something like. Engine Number ABC 1234 . Brush/ H.S. did want to show this engine off. It's just a pity that B.R. did not put this type of loco into fleet service. One of the better prototype diesels in my opinion.

Looking through the photos on the web I did find two photos of Kestrel in Barrow that I had not seen before, one of them is the engine that was one of the most powerful in the world at the time getting pulled along Mickelson Road by a tractor with about a 20hp engine.

Hi Andrew

Heljan did a 4mm scale “Kestrel”. Perhaps someone on here (or on RMweb), who has said model, could wave a magnifying glass over the worksplates, to see what wording (if any), Heljan put on the third line?

That is a lovely piece of work, it's a very interesting prototype & it's a shame it's gone. I remember reading about someone who went to try & track it down.

Despite further research I am no nearer. Other than Brush archives are held in Leicester and may hold the answer.
I have decided to go with :

Sulzer 16LVA24 Engine

Off to see Diane Carney at Kettering.
