About this blog

This blog complements my Pre-Grouping Blog by covering my modelling activities in the Broad Gauge era of the Great Western Railway.  As with the earlier blog, I intend to cover the various methods by which I construct elements of the Broad Gauge scene.  For more background see https://www.rmweb.co.uk/community/index.php?/blogs/entry/17705-a-different-type-of-railway/

Wooden Goods Brake Van

In a previous post, I commented that I felt I was getting the hang of 3D-modelling. That didn’t mean that I can’t still get into a mess and sometimes things happen in ‘Fusion 360’ for which I have no explanation. For example, I was approaching the final stages of the chassis I shall describe below and found that one of the complete axle-box assemblies had moved about a centimetre from its proper place on the sole-bar. Back-tracking through the history made no difference, as the software seemed t

Wheels for my Wagons

I got something of a shock when I saw the current price of Broad Gauge wheel-sets so that started me thinking about 3D-printed wheels. I realised that I wouldn’t be able to make metal rims but it could be a way of making basic wagon wheels in bulk.   Many early GWR wagons used the form of wheel ascribed to Losh and Bell, in which wrought iron spokes were cast into the hub and wrapped around the inside of the wheel rim, to give the characteristic appearance shown in the following illust

What big wheels you’ve got!

I reached something of an impasse at the end of my previous entry in this blog. Lots of problems to be addressed but no clear routes to solutions.   Possibly the most striking feature of the ‘Waverley’ class 4-4-0s was their wholly-exposed coupled driving wheels. I therefore felt strongly that this was an aspect that my model had to capture. Unfortunately, there seems to be no commercial source of 24 spoke, 7 foot-diameter driving wheels and, while I fantasised a little about building

West Drayton Coke Ovens 1839

Background   Almost 10 years ago, I made a model of a lime kiln as a ‘scenic accessory’ on my North Leigh layout. For some reason, I never wrote a blog post about its construction but did write a short article for ‘Railway Modeller’, published in November 2015.   I have, however, described how my model was based on the kiln at Fawler that originally had a siding from the Oxford Worcester & Wolverhampton Railway. Fawler is close to the real North Leigh, on which my pre-gro

Waverley - Between the Frames

Looking at the frames of my ‘Rob Roy’ model, I realised that there is a very visible ‘yawning gap’ between the frames, which really needs to be filled with something. It never bothered me with ‘narrow’ gauge ‘double-0’ models but a 28 mm gap is a different matter altogether.   The instructions for the Broad Gauge Society (BGS) kit of the Gooch Goods, on which I have based my model, contain very little information beyond: “note: the kit provides for two slidebars per cylinder but it was

Vulcan – first in steam

I hadn’t intended to make another model so soon after my previous post but, having read about ‘Vulcan’ being the first engine in steam on the GWR, on 28th December 1837, I felt I should add it to my collection.   Since 'Vulcan' was a sister engine to 'Aeolus', which I have already modelled, I could re-use many of the parts I had already designed, so this was a fairly quick re-build.   My model of 'Aeolus' was based on the 1843 rebuild of the prototype, after the original vers

Taking Stock

On one or two occasions, I have received comments along the lines of “we want a layout”. From the beginning of my exploration of the broad gauge, it has been my intention to produce some sort of layout or diorama to display the various models of rolling stock that I’ve constructed.   Of course I already have a small layout carrying both narrow and standard gauge routes, based in Oxfordshire, towards the end of the 19th century. This layout continues to provide entertainment to my grand

Splashers!

This is a lengthy post, containing a lot of detail about the methods I devised. When I started to write it, I realised that I had already forgotten some of the steps, so I have made this detailed description as a support to my own memory!   From the very start of my plan to construct a model of a Broad Gauge ‘Waverley’ class locomotive, I realised that those bicycle-like splashers were going to be difficult! They are a very prominent part of the locomotive and fit closely around the ri

Six-wheel Luggage Van - 1861

One of the vehicles I need for my planned 1868 Mail Train is a Luggage Van, which was the last vehicle in the train that was involved in the Bullo Pill accident.   When I noticed that the Broad Gauge Society (BGS) has launched a new series of laser-cut plastic kits, which included an early luggage van, I thought it would be interesting to try building one. As readers of my blog will know, I like to scratch-build as much as possible but there is always a lot to be learned from building

Simple Carriage Build

As a diversion from the problems I am experiencing in completing my Waverley-class 4-4-0, I have put together a Broad Gauge carriage body, using photo-printed sides.   I have previously described making various standard-gauge coaches by using my Silhouette cutter to cut out several layers, some of which I pre-printed from photographs of actual coaches. I gradually refined and simplified my methods, resulting in the construction of an early Passenger Brake Van (PBV), which I built back

Printing ‘Eagle’

In my previous post, describing my design method, I wrote:  “This method also means that I do not need to make any of my own measurements but simply rely on the drawing being accurate and traceable”   A lot of early railway drawings were far from accurate!  I found the following in a collection belonging to William Strickland, an American architect:     According to Wikipedia, “William Strickland's Reports are the starting point of American railway engineering, and

Planning a Mail Train

Having ‘cracked’ the main problems with building my Mail Coach, I have started thinking about the other vehicles that made up that ill-fated train. According to the accident report, the engine ‘Rob Roy’ was pulling three passenger carriages, and a luggage van. It is stated that the leading carriage had a break compartment in it, and that the third carriage, which was the mail carriage, also carried a guard.   This leaves me trying to decide what the other carriages might have been.

Photographic Evidence

Having wandered into South Devon territory with my atmospheric caper, I started to look at some of the steam engines used on that line. I realised that, although I have modelled several early passenger engines, including the Firefly class, I have not tackled any of the early goods engines.   The Leo class 2-4-0 were built as goods engines, starting in 1841. It was soon realised, however, that they had insufficient adhesion weight, so all the engines were converted to carry saddle tanks

Pearson’s 4-2-4T – Part One

In a comment on my previous post @Mikkel wrote “I never know what's next on your blog Mike”. Actually, I feel much the same – I never know where a whim will take me next!   A week ago, the thought of a Bristol and Exeter Railway (B&ER) engine was nowhere in my mind and then @Annie posted some splendid photos of Pearson’s magnificent 4-2-4 Broad Gauge tank engines.   B&ER No.42 4-2-4T designed by James Pearson   It wouldn’t be true to say these engines hav

Pearson’s ‘small’ 4-2-4T

After dissecting the workings of the extraordinary 9ft. Pearson 4-2-4T engines in my previous four posts , I was interested to examine how these engines compared with William Dean’s later attempt to create something similar for the standard gauge.   To make the comparison on as level a playing field as possible, I looked up information on the slightly later Pearson engines fitted with smaller 7’ 6” driving wheels – similar to those on Dean’s standard gauge engine.

Pearson 4-2-4T – Part Two

In Part One , I wrote that “this engine had several very unusual features” and, in regard to building a model, “I had to start somewhere and, with so many peculiarities, it was hard to choose. As a ‘gentle introduction’, I decided to start with the two bogies.”   I intend to continue, as far as possible, to follow a line of ‘least resistance’ but before going any further, I collected as much potentially useful information , photos, and drawings as I could.   In his book

Pearson 4-2-4T – Part Three

By the end of Part Two , I had modelled all the most visible parts of the engine and felt tempted to stop there but many of the peculiarities of these engines were below the platform, so I had to keep going ‘down there’.   Photo by Snell of B&ER 4-2-4T No.42   Although I have collected quite a number of drawings and photos, there are still some difficulties in determining the layout of all the parts, especially since some drawings omit features and others show some

Pearson 4-2-4T – Part Four

I ended Part Three with the prospect of modelling the many rods and brackets on the underside looming over me. I had intended to write more at that time but found myself struggling to understand how various parts of the engine fitted together. I think all the ‘easy’ bits have now been done, so I could no longer avoid the complex underpinnings.   To gain an overview, I ‘mirrored’ one half of the split plan-view from ‘The Engineer’ and then colour-coded various elements – blue for frames

Paddington Station 1840

Brunel’s great arched roof is to many people the epitome of Paddington Station but this was not built until 1854. The passengers who first travelled on the line from Paddington to Maidenhead, which opened on 4th June 1838, started their journey from a far less imposing structure – little more than a collection of wooden sheds.   A London terminus for the GWR was needed in a hurry, after negotiations with the London & Birmingham Railway for a joint terminus at Euston broke down.

Paddington Engine House 1840

“Towards the end of July 1837 I heard that Mr. Brunel wanted some one to take the post of locomotive engineer on the Great Western Railway, and I at once went to him, on July 20th, preferring that department to railway making.”   Thus wrote Daniel Gooch about the event that changed his life when he was just 21 years old. As a result, he left Manchester and went to London, beginning his duties with the Great Western Railway at West Drayton on the 18th August 1837. Because no engines had

Open-top Cattle Wagon

Whoo-hoo  – I seem to be getting the hang of 3D modelling, at least for simple shapes like carriages and wagons.  Whereas I had some infuriating moments when designing my first cattle wagon model, its open-top cousin has proceeded with scarcely a hitch.   I decided to follow exactly the same procedure that I used for my first wagon : floor and ends as one ‘body’ and individual sides as two separate ‘bodies’. After printing these separately, I used a soldering iron, set to 200°C, to ‘we

One Step on a Broad Road

After spending a long time reading and thinking about Brunel's broad gauge railway, I knew I had to make a start somewhere. The thought of plunging straight into a layout was proving too daunting so, I decided to buy a display case of the type sold by Antics models This case has a plain wooden base, measuring about 330mm x 80mm, onto which I could build a short length of broad-gauge (BG) track.   I wanted to build my track base using materials and techniques that mirror the original co

Next Stage – Making Rolls

In the previous entry, I described my approach to making sandwich frames. While that was only a small part of building a chassis, I decided to change tack and have a look at how the ‘super-structure’ of the Broad Gauge kit goes together. As I have mentioned before, I am considering how the boiler in this BGS kit for the Gooch Standard Goods might be used to create a model of the ‘Waverley’ class 4-4-0.   To put it mildly, the instructions with the kit are somewhat terse in their descri

My Atmospheric Caper – Part 3

Assembling the Parts   In tackling the assembly of the components that I printed as described in Part 2 of this series, I was reminded of President Kennedy’s words “We choose to … do the other things, not because they are easy, but because they are hard“   I had realised that the assembly of the parts was not going to be easy but it turned out even trickier than I had expected. To re-cap, the parts I printed were as shown below:   3D printed Atmospheric Apparat

My Atmospheric Caper - Part 2

Introduction   In Part 1 of this series, I described my model of the piston-carriage for the South Devon (SDR) atmospheric railway, based on drawings by Paul Garnsworthy in the Broad Gauge Society (BGS) Journal ‘Broadsheet’Nos 44 and 46.   It’s been great to receive so many positive comments – clearly some of my viewers like reading about ‘forgotten’ corners of railway history. They spurred me into getting on with the next phase. Thank you!   The carriage body was r
