I have display models of locomotive from both designers... but for me Gresleys designs seem the most elegant...but the Kings come in very close second and they were a slight evolution of Churchwards Star class
Ah another fopa on my part
Haha... I was expecting that... the Baker was a slight modification of the Walschaerts and its an American innovation so I'd think you take some pride in that ^_^, Strictly speaking its not a valve gear but a variable expansion mechanism adapted to the Walschaerts layout ...
It too had its problems...
"the main criticism being the number of pin joints and possible lost motion. Western United States and British railroads tended to continue with the Walschaerts pattern. In Britain Baker gear was popular amongst model engineers but in full-size practice the length of the yoke and the width of the assembly may have been difficult to accommodate within the restricted loading gauge."
There must be a reason Walschaerts valve gear was used extensively on many gauges from 1910 onwards. it was simple to understand and build, easy to maintain and got the job done...
I'd have to take your word for it ^_^
Though wouldn't Reidinger Poppet valve gear or a refined Conjugated valve gear prove more efficient?
I'm interested. The Bavarian smokebox door is a nice touch, as alwasys.
What would you say her top speed is?
Also, is she mechanically fired?
The firebox design is very clever in itself, as well. Manages to work well with what space it has.
Will she be painted white, as the name implies? I love your white engines.
I should've known it wasn't conical enough!
This is really shaping up to be a mechanical marvel of an engine. I can't wait to see her finished, especially in white.
Will she feature stripes? If so, what color?
I recently saw a great documentary on the last days of the Big Boy engines, called "Last of the Steam Giants". I'm certain you've seen it before.
Anyway, it was the first time I'd seen footage of a stoker screw in motion. It was terrific fun to watch for myself how one worked.
Mechanical stokers are most important on broad gauge lines, unless you either have three firemen or a single blue-blooded giant who can throw coal at least three and a half meters ahead of their shovel's end!
You'd think they're always used on my "International Gauge" engines, which I may reduce from 102" to 92.5". This isn't the case. The very smallest of engines on this gauge, (think LBSCR Terriers and smaller) are often handfired.
The very largest of engines often utilize BOTH a screw and a supplementary man. This man, called a "tertiary fireman", throws coke into the corners the screw may not reach.
You may think tertiary firemen have it easy, but believe you me, they must be prepared in the event of a screw failure!
Mechanical stokers don't typically exist on any engine less than 5 foot in gauge, unless they climb mountains or any other particularly demanding line of course.
That makes sense. Thank you.
I'm not sure what I want for the 102" gauge lines. I want them to have an Anglican taste to them, I know that.
I figure they would be categorized into separate periods, representing different design eras in our continuum. However, this is difficult to pinpoint perfectly. Different collectives (for lack of a better term) would use different technologies.
Good examples of conflicting technologies are the method of boiler cladding, draughtiness of cabs (!), wheel arrangements, and so on. A 'design era', therefore, is very loosely tied together.
For example, the First Era would represent engines built with 1830-40s experience. This is called the First Era because it is the first period of engines for 102" gauge.
The Second Era would represent engines built with 1840-60s mechanical knowledge.
And so on and so forth.
By the 1010s, the latest I plan to write, engines are being built as though reciprocating engines had continued to be built into the 1980s-90s.
An important note on the 1010s is that more modern techniques are appearing in experimental shunting engines. More and more engines are being built with water tube boilers, chain drive, and other Sentinellian features.
This doesn't matter much, because Inglica (England) has achieved it's designated 'edge of industrialization' by this point.
An 'edge of industrialization' isn't so much a plataeu, but how much a country is allowed to expand before a certain balance of nature vs. civilization is at risk.
As I've told you, this planet has a much larger land-to-ocean ratio than we. Therefore, there are more countries to create, and more importantly, PORTRAY.
I think it would be the 1030s before we see anything similar to Bulleid's "Leader" on the main line, albeit much more successful.
Bear in mind, 'conventional' engines with firetube boilers, direct drive, tenders and so on will never, EVER go away.
There's no obsoletion of technologies in my world, trust me.
A dry wall firebox? What kind of educated CME thinks that'll work?!
Sentinellian shunters begin making an impact sometime in the 1010s. They seem to work well, though opinion is mixed amongst enginemen who may favor conventional engines.
A band of individuals of all ranks, 'modernists', are cruel men. They insist conventional engines be totally wiped out in every line of duty.
These men are obviously not popular with railwaymen or the public.
However, a particular foreman has a plan to make this 'revolutionary' nonsense stop.
He provides the modernists with a bet. They give him a road engine design, and he builds it. If the engine is successful, he'll build more.
The public is horrified. But, they don't know just how cunning this foreman is.
The engine is built, and on it's first high speed run, fails with multiple faults. Seized chain drive, melted firebars, blocked firetubes, the works.
This shuts the modernists up, and the engine becomes the first to be scrapped in hundreds of years.
Now, the engine would've failed on it's own well enough, but this foreman made sure poor metal was used in the construction, as well as slack coal burnt, to speed up the process. XD
Thankfully, the scenario was engineered so none of the enginemen were injured.
The modernists became changed men, it's safe to say.
They still have no idea of the foreman's plan. Nor do they know how hard they and their engine were laughed about in the local railwaymen's pub that night!!
Neat on the subject of the islands. Are there a lot of viaducts involved?
