Roundhouse typically pictures their products in bright colors. What it might look like in colors other than military green (?).

Peter Angus locomotives:

 

Interesting R/C only. Any idea on price?

 

$4,600, according to The Train Department.

I guessed Roundhouse went R/C only because it's a lot easier to put a reversing servo in each chassis than build a mechanical linkage which accommodates the articulation.

It's an appealing model, and huge - over a half meter long.

 

Roundhouse website price list 2,859.33 BPS. = 4,330.40 USD (5/11/2015 exchange rate)

I checked and the Darjeeling Garratt price ex VAT is 2,958.33 BPS.
That is three Garratts on the boil now!
They are all going to be quite expensive too unfortunately.

Roundhouse chose correct prototypical colour:

This is how the locomotive appeared in the early years of the service.
There are not many photos known, but here is a nice painting:

I do not know if it has ever been repainted in a different colour. Best wishes from Tokyo, Zubi

 

Best to remember the WHR required two tries to get Edison Green right. Hopefully Roundhouse will come round. That Green (or whatever it's called) is atrocious. Calling that color Green is surely offensive the Green.

The color in the painting is superior to the Roundhouse color. It's positively revolting, and I don't particularly are for it.

DHR D Class
From Wikipedia, the free encyclopedia http://en.wikipedia.org/wiki/DHR_D_Class

Photo Labeled "Beyer-Peacock works photo"

I think a spectral analysis would show the reflectively off the painted area in this photo would not translate to Green. And painting in this photo is in panels with lining. As labeled on multiple locations "Beyer-Peacock works photo" and is probably Beyer-Garratt Grey as delivered to DHR.

Interestingly, this photo clearly shows painted panels and lining with DHR on the bunker unlike the painting or Roundhouse model. It would be interesting to know what reference Roundhouse used for the color and paint scheme.

I searched but could not find any dimensions for the DHR D Class. But this photo does offer some relative comparison to the K1. Relative to the man standing next to the D Class It doesn't appear much bigger than the K1.

WHR K1:

Zubi's posted DHR D cutaway and painting both show panel outlining versus the Roundhouse model which has none. The lining would help the Roundhouse very plain paint job. Panel lining will be available from Roundhouse on the delivered models, if only as an add option.

Final point of interest, you would think, like many other DHR locomotives, the D Class Garratt would have at least been painted Darjeeling Blue; there would be at least one photo of it could find itself somewhere in the historical records.

 

It is nearly two locomotives.

Two full engines. While there is only one boiler, burner, and fuel assembly, there are several components not found on a conventional Roundhouse model: two hinge points in the chassis and flexible steam delivery lines plus one return line. This model also seems to have more detail than is average for Roundhouse.

I'm thinking about ordering one. My coal project is taking awhile, and I don't want to rush that.

 

Small rivets instead of big bumps, one would hope.

Andrew

 

I wonder if the prospect of another Garrett model coming to market, with photos showing it's real, versus K1 is just being planned so far, will devalue the NGG16 Garratt on eBay and it will sell for less than the first?

 

Maybe so, this one sold for a $1000 less.

 

Mongo like

But Mongo poor :-(

 

It appears from those photos the prototype used a drive shaft with universal joints and telescoping sections to control the weigh shafts and lifting arms on each engine - probably the component Roundhouse found too costly to offer in manual control. It looks similar to a Shay's driveshaft.

 

Ahh! well spotted. I was wondering why no manual version.
The below image shows the side with the universal link from the johnson bar to each power unit.
Perhaps there is a servo in each bunker to do this instead of making the link function as on the prototype.
No universal joints appear to be modeled on the Roundhouse model. Maybe it is just some flexible tube to each power unit.

I don't mind drab green locomotives. I have an Accucraft Saxonian IIIK that is drab green with a dull red chassis which looks very convincing compared to the 'jolly' greens LGB uses.

Andrew

 

I wonder if the boiler has 2 burners to feed the 2 pair of cylinders?

 

Well my estimation of the price was the current listed exchange plus 5 or so points as that is at least that of what I pay via payment to Roundhouse for payment. The banks make their money each time. I then estimated about 200 shipping for it to the US. So yes you are about 4600 all in as I expected. Of course if the dollar drops against the pound then its just going to get higher. Still a great looking loco. Cant wait to see the first one lined.

As to the control there is servos for each drive unit that control the gear like the Talesin. That is why there is no manual control.

 

It begs to be coal-fired.

The water gauge is a window in the boiler. Only other model I know that had a window into the boiler was the Frank-S.

What scale is it? 1:19?

Boiler sightglass is a reflex type as used on ride on scales. Much more reliable type.

Also scale is stated at 1:19 per Roundhouse.

 

The prototype is 2ft gauge so it is probably gauge adjustable for 32mm or 45mm. The Roundhouse website does not say but 1:19 is common for 2ft gauge models.
Roundhouse like making outside frame locomotives because it is easier to make them re-gaugable.

It's a Garratt!

Scott,

The works picture looks strange (ie not green looking) because works pictures generally saw the loco painted in a light gray with black accents. The K-1 works picture is the same shading and for a time while it was on exhibit at the NRM it was painted "works gray" as it was called on the exhibit placard which actually looked rather nice IMHO!

I like the works grey too. As I understand the K-1 will be offered in both grey and black.

 

I thought that the model was lacking of detail until I saw the pictures of the prototype. Looks like it will be another awesome model from Roundhouse.

 

The K-1 is offered in grey lined, black lined and plain black.
I have grey lined ordered but now I am swaying towards black lined as it worked in Tasmania.

The Roundhouse Tom Rolt has a similar water gauge.

 

Andrew,Tom & Chris, Rather than read about it, I purchased the Mountaineer directly from Roundhouse. Mine was # 21 of the second batch and they built it to my request, as not having the fuel valve sticking out of the window, Roundhouse is very accommodating.
The water glass is more accurate than the tube type, I personally like it. And I can't see it being as difficult to replace (if ever necessary) or have the bad alignment problems as the tube type occasionally have. LG

 

Hi all,

I've had two Roundhouse Fowler chassis and an old Accucraft Mogul boiler kicking around for several years. The new Roundhouse garratt has got me thinking once again about building my own garratt. One question that has been bothering me is the suspension. The factory photo of the Darjeeling loco suggests that the boiler unit is kept on the same horizontal plane as the rear power unit, and that the front power unit not only swivels, but can also rotate from a vertical relative to the rest of the locomotive. Any thoughts about how this can be replicated in a model?

Ian Pooley

 

If you just had a pin through a slightly oversized hole that was chamferred a little each side it would provide enough tilt so the power unit would remain on the rails if they undulate over the locomotive's length. In fact you could do it to both power units as long as there was a flat washer around the pin so the center boiler section will sit level.

Andrew

 

Hi Andrew

I'm assuming that the washer would have to be held in place by a spring. I'm thinking of the way the Accucraft shay trucks are held in place by a bolt with a spring on the bolt shaft.

Second question: will the Accucraft Mogul boiler have enough steam to supply two sets of Roundhouse cylinders?

Ian

Yeah Ian. That is where my thoughts were leading. I was primarily thinking of the tilt rather than retention. Use a bolt for the pin but have no thread where the chambered hole rubs, maybe a sleeve. It wouldn't need a lot of allowable tilt if done at both bunker pivots. I think it would need to tilt at both pivots because of the geometry when on a sharp curve. The spring would help the boiler from wobbling. More weight in a live steam boiler full of water than a plastic model so that has to be considered. It's only a simple approach to a pivot that has some side tilt but I'm sure it could be a lot more sophisticated.

Andrew

 

Hi Andrew,

A second comment: the plans for the original Darjeeling Garratt in the Peter Manning book show that the front pivot contains a spherical casting and the rear pivot has a flat faced centre and a side bearer on each side of the side frames.

Possibly to power two sets of cylinders it would be better to use a large boiler with two burners, eg: a Tich boiler kit from Reeves in the UK.
