Wagga Wagga station - roof -1

Roofing Wagga station - 1

After the last blog post, I looked at the prototype photos of the roof, and noticed that the trim above the corbels was thicker than the trim on the triangle sections.  So before I did anything, I added some additional styrene strips to bulk this area up to match photographs. 


Pegs make a convenient clamp for the extra styrene. 

I had also thought about guttering.  All of the gutters I had added on my structures up to now, were simply  1.5mm angle styrene strip. Whilst this works, it is mechanically weak.   The Wagga station allowed me to experiment with an alternative, which the below diagram attempts to show


The angled corrugated styrene rests on the gutter strip

The 0.010 x 0.250 styrene strip  was added on top all around the station walls (but not on the triangle sections).  Some 0.010 x 0.040 strip was added to form the guttering in a few places to check out my idea.

The guttering is a prominent detail. I have tried to smooth the join between the two sections of styrene above the corbels - although the camera shows that I was not totally successful in this task

Guttering detail from above


.I thought reinstatement of the North-south triangle sections of roof would be a good first start.  I made up the triangle pieces for the platform wall sections.  After careful measurements, I then fabricated 8 more internal triangle sections (4 on each side).  These triangle sections rest on the guttering 0.010 x 0.250 strip, but leave enough of a gap between the future corrugated iron styrene and the guttering 0.010 x 0.040 strip.  A number of solid beams were then cut, to join the lot together




The North-South roof section fits between the triangle wall details.  The smaller intermediate triangle sections were sized to fit on the wide gutter strip as show in the diagram earlier.  The notches in these triangles were cut out with my nibbling tool.  This selection of parts is the first group of two needed


My nibbling tool is a much used tool.  I bought my first one at Tandy (remember that electronics store?), but after it wore out from overuse, a replacement obtained from Jaycar.  Extremely useful for cutting squares in styrene, and thinner sheet brass


The nibbling tool cut a channel into the styrene that was almost exactly 0.080” deep certainly matched my 0.080 x 0.188 styrene strip (the size I also used to bulk up the walls above the corbels). 

These parts were then fitted in situ on the station.  There is no room for sloppiness here – the roof has to fit snuggly, and the end triangles key the roof into the correct position.  I allowed 24 hrs for the glue to fully harden


Juggling all the angles to get everything square needed a lot of luck, and perserverance. I used two types of Tamiya styrene cement - one was thicker, and allowed for minor repositioning prior to setting - the other type was instant fix. 

After the joints had dried, the assembly was  removed from the station, for measuring up.  Note the rebate in the end triangle areas for the snug fitting of the corrugated styrene.

Adding the corrugated iron was next.  To save material, I didn’t run the full width with the corrugated styrene.  To do so, would have prevented a neat join with the east/west set of roofing iron.  The heavy styrene beams hold the shape well.

 

The corrugated sytrene was cut into 4 sections, and  was glued to the beams, and end triangles whilst attached to the station. The effect with the guttering is just visible. 

So far, I am pleased with the effect.  However, It is just the first step.  There is still a lot more roof to add.  I have not yet decided if the entire roof will be one section, or if I will have the center section removeable (Which may give me a change to have a detailed interior waiting room).  Then there is the matter of securing the roof to the walls (screwing is the thought) – plus the chimneys.

===============

I am still getting used to the new google blog interface  No longer can I preload all my pictures, and select the ones that I want for insertion in the text.   But it does give better stats.  I noticed that my blog-post on oil depots has now passed 1000 views.  It is 350 views ahead of my next most popular post on the Auscision RUB set.  Maybe these are things people search for in Google?

 

Trust you have found something of interest in my roof construction approach, particularly with the guttering.  Until next time.

Wagga Wagga station - Assembling the walls

 Wagga Wagga station construction - Part 5

The only practical new year's resolutions that I hope to continue well into the new year, is to do at least 30 minutes of modelling each day.  Will see how I go.  So far, the effort has been worthwhile


Part of the crowd in 1954 assembled to greet the Queen during her vist to Wagga Wagga. The railways played a good part in running specials, collecting school children from around the Riverina. The coaches stored on the goods sidings gives some idea of the number of trains needed

The Platform side station walls detailing was carried out the same way as the roadside walls.  All were detailed flat on the workbench, and then assembled into sub assemblies.

The eastern end platform side wall.  The two windows were originally doorways, but I had earlier made a decision to model the current heritage design, so I had no choice

Roadside and Platform main entrances were almost mirror images of each other, the roadside has "keystones" which were absent on the platform side.  However, I had assumed that was the only difference. But I was mistaken.

Platform side entrance doors are more spread apart than ....

...the roadside entrance doors which are closer together

This was a whoopsie.  And a close inspection of the plan also shows this.  I pondered a while to think how I could correct the error.  I could not come up with a simple fix.  And I didn't want to construct another wall - So, as the platform side is not visible from normal viewing angles, I simply decided I could live with the error. 

I had cut out a 530x77mm sheet of styrene to fit the base of the station.  To allow for a later access to the roof (I am thinking I will attach the roof with screws), and to give me a source of styrene for the window/door inserts, it made sense to me.

The 3 main subassemblies now glued to the station

On the last blog post, I hinted that I had a problem with the triangle roof ends, in that the walls had warped forcing the triangles out of plumb.  (and I thought these were braced enough to prevent this)  My original idea was that the roof would simply slip behind them.  This wasn't now going to happen.  So, now was the time to take them off, which was a little tricky.  The triangles will now become an integral part of the roof

The large platform arched doorways under construction. 

Now that the station is in one piece, I needed a base to put it on.  This floating floorboard was convenient for now.  The roadside front walls have been attached.  I used sheet styrene for strengthening the 3 subassemblies which you can see in this view

The platform arched sections now attached.

Next stage will be to add the roof.  I hope this will be a lot faster than the walls 


Just before new year, I went down to the Junee Roundhouse museum, renewing my membership, and purchased the latest A5 booklet on the Tumbarumba branch.  It is titled "Wagga Wagga to Tumbarumba Railway - an era of change".  It has a red cover.  Very similar in style to the earlier booklets by the Tumba Rail group, showing a collection of recently acquired photographs - some I found most interesting from a modelling viewpoint.  I believe the booklet is also available for sale at the ARHS bookshop.

Until next time, build a model or two.

Wagga Wagga station - Platform side pictures

 Wagga Wagga station construction - pt4


I managed to get over to Wagga station 2 weeks ago - and arrived just as the Melbourne bound XPT was departing. Sorry, I had hoped to capture a picture of the train, alas, it wasn't to be.


A picture from the past.  Blue livery Countrylink on the platform, with the Melbourne bound steel train on the main. The original heritage colours of deep maroon, and cream is probably the scheme I will be adopting for my station

However, the main reason for the visit was to photograph details of the station on the platform side













A selection of pictures at the start of December 2020.  Note the platform seats have social distancing due to Covid19 restrictions.  Also note the extensive metal lacework.

As my only plan of the platform side, is in the end-papers of the book "The Greatest Public Work", by Robert Lee, I was quite chuffed to discover that most of the windows, and doors were virtual clones of the ones on the roadside.   Of course, there are some differences, and I measured those.


                    1879 Plan of Wagga Wagga station.  This would be a great plan to frame.

  And there were some differences from the 1879 plan - noteably two doors on the eastern end (RHS on the plan above), had been converted to windows.  I will build what is there now





Initial cutouts for the 5 main wall assemblies for the platform side.  I have not yet made the distinctive triangle parts for the roof (like I did on the roadside view).  I subsequently discovered a warp in the styrene backing for the roadside triangle area. Whilst this is fixable, I would rather avoid creating the same problem on the platform side.  


I have made a start assembling the walls into a proper structure.  Blending the "stone work" on the corners is something that I found impossible to do when the walls were flat.  Both the roadside ends are now ready to join into the platform walls, once they have been detailed.  Keen viewers will note that there is another "room" to be added onto the end walls.  An assembly task that can wait for now


A triangle gusset assists in strengthening the join.  I have left a 0.040 gap at the bottom for the future "floor". 

I wish everyone a happy xmas, and a more productive new year.

Until next time.

Wagga Station Building construction - pt 3

Modelling challenges 

Yesterday, whilst I was at the workbench,  a storm brewed up to the west of Junee, and was about to make its presence known.  It hit my place around 1pm, but as I discovered later, my place got off lightly, with just broken tree branches, and upturned pots on the veranda.


The Junee Roundhouse lost part of its roof in the Nov 28th, 2020 storm

It is often said, that when one builds a model, to show off the interior, one should make the roof removable.  But I don't think this is what they meant

The roofing iron from Bay 7 is drapped over the exhaust vent of bay 8

A wide angle of the previous shot. Quite a number of Graincorp 48 class engines are stored in the open.  The Graincorp 48214, previously 48148 shows evidence of the poor standard of the latest paint

Roofing iron from Bay 15, 16 or 17 were blown towards the east, and landed on the stored 48/830 engines.  This and the below 2 pictures were taken off the Junee Community facebook pages,  The iron had been removed by the time I took my pictures. 

Probably the brightest "inside" view of the roundhouse I have seen.

48 class locos being refurbished/serviced in anticipation of the bumper harvest. The roofing iron over bays 5 and 7 had been peeled back.  It is possible that this iron was originally installed in 1947 when the roundhouse was built.
==========

Anyway, back to the Wagga Wagga station build.  As I mentioned on my last blog post, I am recovering from a nasty leg infection.  As a result, I can only spend at most an hour at the workbench, before I need to have a break, and rest my still partially swollen leg.  The upside, is that I am trying to get two or three sessions in per day, in the morning, after lunch, and around 7:30pm.  Progress is now steady.


The main entrance wall has been fleshed out.  I try and make small improvements to my process.  The  doorway on the RHS has had the arch detail installed, and by using the 0.040 styrene below as the guide to "hollowing" it out, I saved a bit of time over the previous brass pattern method.  Once the arch is formed, then the door insert will be added - result looks like the door on the LHS








Marking out the parts was a matter of using my field measurements, converting them with a calculator to 1/87, and drawing them directly on the styrene.  I even broke out my high school tech drawing compass for the arches over the windows



One of the windows on the LHS veranda.  

The LHS Veranda has 3 sets of windows.  It is effectively a mirror image of the RHS veranda


After some more detailing, the pair of wings looked like this.  RHS on top, LHS on bottom

A washed out image due to the sunlight, and the dark background, but 5 sections routhly positioned to show the main station size.



Further detailing on the LHS wing.  The plastic count of parts of just this wing is 233.  It is important when building walls to get as much detail on them whilst they are flat on the workbench, because once they have been assembled into a 3D structure, things become more awkward, and the structure is subject to damage.  The main Wagga station is around 550mm in width, not counting the small extensions at the ends, that will be made later.  

I will not kid you in saying that this build is straight forward.  Just from a time factor.  Already, there are some  (hopefully) minor errors that will be difficult to correct.  I may  fill you in later with these, but the upshot is, I have enough building left without worrying too much to rework to get things 100%.  I will learn from the experience should I ever have to build another model of this complexity.

But, I have to get over to Wagga again, and take detail shots, and measurements of the platform side wall.    My current batch of pictures was taken from Railway Street, and whilst probably OK, as this side will be hidden from viewing when the station is planted on the layout, I would like to get it right.  I was told the best time to view is after the departure of the Melbourne bound XPT.

Until next time, stay out of the wind.
