The largest size of Burton cask, the butt, was 4' 4" long by 2' 9" diameter at the waist, held 108 gal, and had a weight when full of 1314 lb - 11 cwt 3 qtr in wagon-speak. A tun, with twice the capacity, would have a weight when full of twice that - roughly 1 ton, unsurprisingly - but linear dimensions only 26% greater. That would certainly be well within the capacity of a 6 ton wagon.
 

So a "tun" is not a Burton cask?  What is special about "Burton casks"?

Would a tun be carried in an open wagon?

I've been asked a question which is outside the competence of someone who isn't much interested in anything after c. 1902. When were the rectangular cast wagon number-plates introduced?

 

 

My hypothesis is that they came in with the abandonment of the cast number / GWR / load plates on the livery change of 1904 but like those cast plates they were only used on new-built wagons and not retro-fitted to older wagons.

 

I think that you are somewhere near with that hypothesis and unless someone has the relevant minutes then your comment is likely to remain a hypothesis.  What I can do is to look through my copies of GWR wagon drawings and find those which include the rectangular plate as per your photo - hence we have a date of when the drawing was registered.   'Mite' not be before the weekend.

If the photograph is pre-1930 then no longer under copyright so please consider posting here.  You may wish to add "published under fair use" / "no claim made as to copyright or ownership".

What does Cooke say on the matter?

Maybe "modern" is not an appropriate adjective for rolling stock from the 1980s...  what I am referring to are the VDx and VGA/VKA vans of the late 1970s and 1980s.

Have any of these designs become part of the heritage scene and, if so, where?

thank you, Graham

So what have models have you made in the past four years?

No one is going to believe that you have just stopped given your expertise / skills / dedication.

... especially look for U-666, "Dediserve" which is the main suspect of firing the fatal torpedo.

Nope, the torpedo was full of molten steel and a dud in the water...

Captain Did-not-Serve is responsible for failing to put the plug back in the bilge hole with the result that the sinking of RMW was a prolonged affair and with no photographic record of events during the last twelve months.

Here we are, clinging to the wreckage of RMweb...

Must have been some train wreck, I have searched U-tube and as yet have not found any video of the event.  MIght have to wait for the RAIB report.

But I'm not convinced that the lower roof isn't a single arc.

Stephen,

I am with you on the main roof of the second carriage - I think that this is a single arc roof rather than a three arc roof.  To my eye I can see, on the leading carriage, a flattish portion of the main roof adjacent to the clerestory...   I do not see the same characteristic on the second vehicle.

I am asking for sight of GWR drawings because the book noted above does not provide sufficient information for printing 7mm chairs where the rigidity of the chair print imposes constraints that are not so relevant when using ABS mouldings.

The membership  of RMWeb often provides a wide coverage of all aspects of railway construction and a response within a few days so asking here first seems such a reasonable step.

regards, Graham

I am looking for Swindon drawings of the 1S and 2S chairs which were used with loose heel switches from circa 1900 onwards - so drawings dated late 1890s to early 1930s. The need is to help with producing 7mm scale 3D printed chairs - rail section is probably not important for the task in hand given that the printed chairs have to work with 7mm bullhead rail.

Anyone got anything or know where to look?

thank you, Graham

A line of bog-standard Midland D305 dropside wagons...

 

Well, there's plenty more to say, especially about the wagon nearest the camera.

 

Yes, lots, so please start with explaining the reason for the white X on the curb rail - is this a painted letter?  a chalk mark?

The curb rail appears as a darker colour than the body side - a repaired timber?

The push rods for the brake blocks appear to be "in-line" rather than a shallow Vee which suggests that the rubbing face of the blocks  are chamfered to the cone angle of the tyre.  Is there an wagon drawing for these wagons in the study centre? what does that drawing show for the brake arrangement?

thanks and regards, Graham

I am a S7 modeller and I agree with what Simon has written above.

Some pictures would be useful.

The prototype is the British Rail VGA from the 1980s.  Thought to be extinct in the wild there are some of the breed to be found in safari parks run by the MoD, for example CAD Kineton and Bicester (can be spotted using Google satellite - last time I looked there were about 30 examples to be found at those locations).  There is an infrequent traffic flow between Ludgershall and Kineton, one arrived at Ludgershall in late November and was there a few weeks back - unfortunately on MoD land and behind a wire fence, up against a loading bank so underframe not visible).

I am advised that there is a traffic flow between East Moors and a secure warehouse a short distance north of Burton-on-Trent.  Google satellite shows several of the breed at East Moors, again on easy access.

Creating a 3D model of a 1980s wagon and that wagon has roller bearing axleboxes and parabolic  springs.  I cannot find information or drawings of either detail on the internet...  can anyone point me at possible sources?

Same question posted to "7mm modelling".

thank you, Graham

I meant to say, imaginary brake shafts still. They ought to have gone in when the models were built; too fragile now.

Yet another chance to use what we had and then lost...  please accept a "groan" which is made with support and appreciation for what you achieve.

best wishes, Graham

Purchase of a smaller, quieter, compressor has made this item surplus to my needs.

No longer available.

Apologies if my most recent pots is confusing / ambiguous.  Your annotations to the drawing are the parts of the design that I do understand (after seeing your drawing).  Referring to your drawing, the operation of the two transverse levers either side of the air-brake cylinder, and the way in which the brake force is appled to the longitudinal pull rods, is the design feature which confuses me.

Just where are those levers "pivotted"?

thank you and regards, Graham

obviously your handbrake arrangement is different, but this shows the functional components....

Agreed in regard to the handbrake.  The drawing explains how the brake force is transferred from the inner to outer brake yoke at each end, I now understand how that linkage works.  Where I am at loss is the reason for four transverse levers arranged to work in pairs - where are the pivots for those levers?

regards, Graham

Nice photographs especially as the first few are of a Pickering build and that is the prototype for the kit.

Thank you.

Here is a photo showing progress in constructing a JLTRT 7mm kit of a TTA, prototype wagon appears to have been built by Pickering of Wishaw.

My knowledge of the modern wagon is poor and so I hope that other RMWers can fill in some blanks, for example:-

a/ how does applying the air-brake cause the brake blocks to be applied to the wheels?  (what gets pulled / pushed?  what parts of the air-brake gear are not provided in the kit?)

b/ the kit provides wire to produce the safety loops for the four brake yokes and castings for the safety loops for the handbrake pull rod, also castings for the paired levers in the centre of the underframe.  What other safety loops exist on the prototype?  Any photos which show such items?

thank you Graham

I found that my sound fitted class 14 wouldn't operate on DC straight from the box. The sounds would ramp up with voltage but there was no movement from the motor. Same issue occurred with a second example passed to me for numbering. Both operate fine on DCC. I found that changing CV13 from 19 (as supplied) to 1 fixed the issue and allows it to run on DC with sound operational. Setting CV 13 to 0 will allow operation on DC without sound. Hope this helps anyone experiencing similar issues.

 

Also good to see that the stay alive works on DC as well as DCC.

Just so I can understand this comment...  the loco has sound and the sound is available when the loco is running on DC; does this mean that the loco has a DCC chip fitted?  Is the chip from Zimo or ESU?

thank you, Graham

Given that the Minerva models have been available for several months I have yet to find a critique of the products - that is commentary on accuracy, detail and finish.  The lack of such a critique surprises me when I think about the "comments" which were posted on RMWeb before production of the covered iron wagon and the open wooden wagons.

Anyone run a ruler over the V4 and V12 models?

A similar topic has been created in the Minerva sub-forum.

regards, Graham

Given that these models have been available for many months...  has anyone written a review of the models?  I am surprised that there have been no comments on the accuracy / finish / detail of the models given the number of posts about similar matters in relation to the iron covered wagons and the open wooden wagons.

regards, Graham

Stephen,

There was I epecting that you would provide a link to hundreds of photos of thousands of PO wagons in Alyesbury (LNWR) yard - together with one or two D299.

thank you, Graham
