I managed to 3D the entire building, I need to clean the stringing but I am rather pleased.

I don't use Blender but Fusion 360, I have printed a test piece of wall which seems to have come out ok. I need get the painting ok as the building has black motar. the test piece has has a blow over with white primer.

Having printed off a section of wall things didn't look quite right the height of the doors were a bit too low, the number of courses of bricks were correct, so a site visit followed I had assumed bricks where at 3in pitch between course 76.2mm so 1mm on the model. getting the steel rule out the bricks were actually 82mm between courses. so I adjusted the model so it now is totally correct including the window recesses that are 9 inches (3mm) om the model.
Well I an now out of the funny farm but I now have lovely brickwork!

Those people like me who have a resin printer but not a FDM one it might be looking at local companies who can print your files, there is a company less than a mile from me who will do it so I am going to get a quote rather than investing in a machine,

First time I have been to Warley as a paying visitor for quite a few years, I did think there was something lacking at this years show.
There were a few trade stands were not there this year as well as demos that I had found interesting in previous years also missing.
I expect the costs now to attend Warley as a trader are huge and that the smaller specialist traders don’t go for this reason.

I've wondered about this and have thought that it might not be commercial in view of the extra tooling costs involved and the limited area of operation. The to90ling depends on how the model is constructed but I am presumaing that the boiler and tans might not be separate parts - a 97XX would be simplet of they were (but obviously that's a design decision long past in terms of the originial style tanks).
But if you can afford to tool snaphead rivetted tanks for basically a small part of the overall fleet size does that mean a 97XX is affordable albeit at a higher price point? Small specialised gepgraphically limted classes do seem to sell and as people keep on doing them presumably they continue to sell? So that's a possible maybe?
Another 'possible maybe' is thaht while the condensers were very geograhocally restricted ine where they worked they were some what wider roaming in other ways asthey obviously went away for main work overhaul. 9710 was overhauled at Caerphilly Works in 1961 - where it was photographed. And, according to BR Database 9708 was reported passing through the Birmingham area, light engine, in 1953 'presumably on its way to Wolverhampton works. and of course the class regularly went to Swindon for shopping.
So perhaps a slight excuse for seeing them away from home. A tad unusually the only place I ever saw one working a freight train was at Baker Street, heading towards Edgware Road on a Saturday. But normally it was a case of seeing them on Old Oak - Paddington empty coaching pilot turns
Here is 9707 out on a PW train at West Wycombe Saunderton area.

Is there a chance that the 97XX condensing version may get produced?

The Sharp Stewart maybe would be a good choice I am not sure how many were built but were used on the Furness Railway, Weston Cleavdon and Porteshead Railway & The Watlington & Princes Risborough Railway there might be other as it was a standard design.

NewburyFarthing station.I'm gradually building up the walls with multiple laminated layers. I found it possible to cut 2mm foamboard right through with my Silhouette cutter, which is fairly deep for these machines. But as seen below, it is not a very neat cut.
So instead I went for sheets of 1mm Foamex from Green Stuff World. The Silhouette cuts this neatly, but only partly through because it is much denser material. So good old hand cutting is needed too. Am I the only one who enjoys that delicious “snap” when a component breaks free?
Here is the first layer of Foamex fitted behind the brick "skin".
A homemade kit of parts is developing.
Test examples of the single and double doors and windows were cut and built up. They are a bit scruffy, must be my gluey fingers. Still a schoolboy after all these years.
But rather than build all the doors and windows individually, I decided to cut them in full layered sheets. So far there are three of these layers, as seen below.
Below are the three layers overlaid. Arguably a little wasteful, but it results in a full and even layer of sheets, which themselves add strength, and behind which further layers can be added.
Here are the window- and door- sheets placed behind the brick skin and the Foamex. The doors look a little flat, so a further layer is on the way to increase depth.
The whole thing will eventually be fitted on a carcass of Foamex, but not before all the details have been added while the walls are still in the flat.
Looking good, I am working on a model of Princes Risborough station which is a similar design, I am thinking of 3D printing the carcass of the building and having laser cut windows and doors, if my idea works I can create the rounded corners to window and door reveals. attached is a couple of screen shots of my model in Fusion 360.

Many of the laser kits I see I don't think look like real buildings with either butt joint corners or very visible corner interlocking.
The brickwork tends to be stretcher bond which is incorrect for the majority of railway buildings, plus there tends to be no depth to walls with doors and windows laser cut on the same plane as the walls.
There are exceptions like Monks Gate Models and Intentio Models who do under stand how real building are constructed and look.

Having drawn up the waiting room, I thought it might be an idea to 3D print the shell of the building and add laser cut doors and windows, The only issue is to add bricks to the 3D model with the correct English bond brickwork with queen closures around corners and door and window openings, lets just say this took me a couple of days to do! Using Fusion parametric input I can adjust both the width and depth of the mortar courses, at the moment they are both set at .1mm

I have now drawn up the trackwork in Templot and am going to try the plug in 3D printed trackwork. I have also started to draw up the waiting room which I have drawings for the buildings on the up side still stand so this is useful for reference.
I was going to laser cut the buildings but might try and 3D print the carcass and add laser cut window and doors.David

It will be my first visit to Uckfield show on the Saturday then doing the Bluebell Railway on the Sunday so staying in Uckfield on Saturday night are there any decent real ale pubs in town or curry houses?

The Down line was partly the old single line Wycombe Branch as well as a brand new up alinement there was a easing of the old line to form a new down line just north of Saunderton the old Wycombe line can still be seen between the new up and down lines a short cutting survives and if you look at OS maps the old line is clearly showing.

Be careful, David. The signals changed (ouch) at Princes Risborough depending on who was responsible for S&T at the time. Sometimes if was the GWR/BRW at others the LNE/BRE or BRM and the signals were changed to the appropriate type s you need to check photographs of your chosen period. The signal in your photo reads: top arm to Watlington or Thame Branches (there was another signal further on to take you to the actual line) lower arm onto the Down Platform Loop.
Thanks Mike I know when rebuilt in 1905 it was GWR lower quadrant changing to LNER upper quadrant in the grouping then changing back to WR tubular post in the late 50s maybe early 60s, I guess not all the signals were replaced at the same time. Although on the model I could go for replacement drop in signals if needed.
Any more photos of the area I intend to model would be welcome.
-
Some more photos of the area I plan to model just showing the interesting trains that I can run including a J15 sunting a GWR brake van into the private siding, the white gate to the siding can be seen in the last photo.
There is even a LNER upper quadrant signal I am not sure why it has too stop arms, one for Oxford and one for Watlington maybe! All this in six feet and for points.
I have watched a video where a prairie tank on a two coach train leaves for Oxford while a a standard BR 2-6-2 is shunning on the rear line.

With a time period from the 1920s to mid 60s there will be lots of stock that can be used, large prairie tanks with two coaches, or GWR streamlined railcars, auto coaches on the Watlington but not with auto locos so had to run round. then when passenger services stopped they used LNER J15s on the branch so will have those. and going to the diesel period Hymeks and D63XX.
I will model platform 3 too so that opens up quite a bit more, although a King on a 12 coach train is not gonna fit in the fiddle yard!

Diesel railcars from Oxford and panniers with Autotrailers shared the same platform at the same time.

Are you going to join it to the Aylesbury layout?
No this is a stand alone cameo layout .

I am thinking of building a cameo layout of Princes Risborough platform 4 For the Scalefour challenge . It was a bay platform where trains terminated from the Oxford and Watlington branches. There is also a gated private siding and a goods loop round the rear of the waiting room as per the attached photo.
Total length of scenic area is 6 feet and the idea is that with a removable backscene could be viewed from either side. the fiddle yards would be 2.5 feet long using cassettes.
With only four points it is quite compact, and there is plenty of different rolling stock that can be used.

In theory there is this 25" OS map which is stated to have be revised in 1919. In practice OS map revisions between the two wars rarely meant a resurvey and just incorporated a few known changes. If you can't find anything else it would definitely form a basis, especially if you can find contemporary signalling diagrams.
It may also be worth overlaying it on what is there today as recorded on Google Earth. Inkscape has a convenient overlay tool if you have nothing else.
That's the sort I think I need, although it does not have the lab siding but its workable for me.

Add:
Princes Risborough Thame Oxford Railway - OPC - Lingard - has a plan - but probably too feint to be of use - also has drawings of some of the buildings - which you could probably scale off - though scale isn't obvious. If you're thinking of modelling the station the book would be worth having.
Yes I have the book, although published in the 70s is still quite useful, I also have both volumes of Wild Swans Watlington Branch. Lets just say I am working on a something cameo layout wise!
-
I was looking for something that shows the two lines of rails so I can scale.
