4+6 VideoMoon Machines: Lunar Module (4/6)
Robert Stephenson and Company built 33 with Stephenson valve gear , while Neilson and Company built 35 with Joy valve gear.
Of these locomotives, 26 were still in service when the South African Railways was established in Tilney, Locomotive Superintendent of the Cape Eastern System at the time, to be able to use low-grade local coal.
They had Joy valve gear and unusual six-wheeled tenders, with the leading axle mounted in a rigid frame and the other two axles mounted in a bogie.
One of the locomotives survived until and was designated SAR Class 04 as an obsolete locomotive. In , the CGR placed a second batch of thirty 5th Class tender locomotives in mainline service on all three Cape Systems.
They were similar to the previous batch of , but differed in respect of the diameter of their coupled wheels, the length of their smokeboxes and their tractive effort.
Nevertheless, some of the Class 05 locomotives survived as shunting engines in SAR service for another four decades. They were the last obsolete locomotives to be still in service when they were eventually withdrawn in It was to become one of the most useful classes to see service in South Africa.
In , when they came into SAR stock, the 6th Class family was reclassified into twelve separate classes. The locomotive was not classified, but named Portuguese and referred to by name.
In , the CGR placed six Type B locomotives with eight-wheeled bogie tenders in service on the Avontuur narrow gauge line in the Langkloof.
They were built by W. Bagnall and had bar frames, copper fireboxes and Stephenson valve gear. In , they came into SAR stock and, in , a further three locomotives with slightly longer boilers were acquired by the SAR.
One of these was also built by Bagnall while the other two were built by Kerr, Stuart and Company. These three were commonly referred to as the Improved B.
When a system of grouping narrow gauge locomotives into classes was eventually introduced somewhere between and , they were to be classified as Class NG8 but had already been withdrawn from service.
They were very similar to the Bagnall built Type B, except that they were equipped with Walschaerts valve gear. They were later designated Class NG9.
They were sold to the Sudan Railways Corporation in Within five years, however, the wheel arrangement was being used primarily on passenger service, since British heavy freight trains were generally too slow to require a locomotive with a four-wheel leading bogie.
Between and , the became the most common express passenger locomotive type in everyday use in the United Kingdom, as a logical development from the type that was previously used.
The type continued to be used as mixed traffic locomotive until the end of steam in the United Kingdom in Soon afterwards, these were followed by the appearance of other designs.
Two notable express passenger designs appeared in Robert Urie of the London and South Western Railway LSWR introduced three successful classes, the H15 class mixed traffic locomotives, introduced in and built until , the N15 King Arthur class , with 74 locomotives built between and , and the S15 class , with 45 locomotives built between and However, from the early s, demands for more power and improved performance from express passenger locomotives led to the widespread introduction of Pacific locomotives, where the trailing axle could support a larger firebox.
Since the reduced traction of the driving wheels was not a big disadvantage with relatively light passenger trains, the was displaced from top-rank express services on most of the railways where they had been used, with the exception of the GWR who continued to build both mixed-traffic and express passenger s until nationalisation in Frederick Hawksworth later developed the Saint class design further, first with his GWR Modified Hall Class , with 71 locomotives built between and , and then with his GWR County Class , with thirty locomotives built between and The LNER inherited large numbers of locomotives from its constituent companies, many of which were subsequently rebuilt, so that the company ultimately had sixty different classes and sub-classes with this wheel arrangement.
In addition, the company also introduced two new classes. Following the formation of British Railways in , two further classes were introduced, both in There are still conflicting opinions as to who the original designer of this type was.
Sellers attributes the design to John Brandt who worked for the Erie Railroad between and Through the s and into the s, demand for locomotives of the wheel arrangement grew as more railroad executives switched from purchasing a single, general-purpose type of locomotive such as the American at that time, to purchasing locomotives designed for a specific purpose.
Both locomotives were rescued and purchased by Disney imagineers Roger E. A locomotive of the type is on display at the Casey Jones museum in Jackson, Tennessee.

Currently, this support is limited to using certificates with a public key which has an exponent no more than 32bits in length. WCF now has the ability to include OperationContext.
Current with ExecutionContext so that the OperationContext flows through asynchronous continuations. The following example demonstrates OperationContext.
Current flowing correctly across a thread transition:. Previously, the internal implementation of OperationContext.
If there was a change in the execution context of the method call i. With the fix, the second call to OperationContext. Current will deliver the expected value even though threadId1 and threadId2 may be different.
An application that requests a CollectionView to group data can now explicitly declare how to sort the groups. This overcomes some unintuitive ordering that can arise when the application dynamically adds or removes groups, or when the application changes the value of item properties involved in grouping.
It can also improve the performance of the group creation process, by moving comparisons of the grouping properties from the sort of the full collection to the sort of the groups.
The feature includes two new properties on the GroupDescription class: These properties describe how to sort the collection of groups produced by the GroupDescription , analogous to the way the properties on ListCollectionView with the same names describe how to sort the data items.
There are also two new static properties on the PropertyGroupDescription class for use in the most common cases: For example, suppose an application wants to group data by Age, sorting the groups in ascending order and the items within each group by LastName.
This improvement is critical for scenarios where multiple displays of varying DPI level are attached to a single machine.
In previous versions, you would have to write additional native code to enable per-monitor DPI awareness in WPF applications.
This is due to a change in the way the touch keyboard tracks focus in applications starting in Windows 8. Once again, we would like to thank everyone who provided feedback on the 4.
It has been instrumental in making 4. Please continue to direct your feedback towards the following places:. You must be logged in to post a comment.
Getting the blocks removed from. Another important piece is that Windows has also unblocked long paths in the Summer Update for Windows See my blog on how to enable the support in Windows.
PowerShell is the first useful tool that has opted into this new support. Much more is in the pipeline. Long paths will work if 1 the OS supports it and 2 the app is targeting.
Same is true with. So take this feature in. Prioritizing our continuing work benefits greatly from feedback. In the above post is says: As far as I know the only operating systems that supports long paths today is Windows 10 anniversary edition.
Does this mean that applications running on Windows Server R2 will not support long paths even if they are targeting.
The only OS that supports long paths without you doing any extra work other than enabling the feature is Windows 10 Anniversary Edition.
You can look at my blog posts for tons of details on what works and how it works. With the feature turned on. We want to do the same thing in 4.
Thanks for the clarification. Given that Windows 10 is a client OS and the problems for us at least surface in server editions predominately are you aware of any plans to back port this feature into Windows Server R2?
Any links you can share on the plans to resolve this in the Windows Server world — or would be useful. I have nothing specific I can share on Server, but I would expect that the changes will come in Server as well.
It is the same codebase after all. There have long been advocates for this space around MS and we will continue to push on the problem.
Keep your feedback coming- the more user feedback we get the easier it is to prioritize this work against other features. Hey, In the sample for the path switch you used incorrect runtime version: But it should be according to the description.
Actually you misunderstood his example, he was giving an example for when you target a lower level runtime. In this case you need to set the additional AppContextSwitchOverride as in the example which would not be necessary when he targeted 4.
For all versions of 4. You response to Michel seems to imply that a new version of. NET such as 4. Is that what you are saying?
Regardless, is there or will there be a switch that will block installation of 4. I might be missing something. If anyone else is curious, targeting 4.
Reading between the lines in the release notes, it seems that 4. Hmm, the installer insists: I checked the list of installed programs and 4.
Happens with both the web and offline installer. NET is a system component on Windows 10 and 4. You still need to install the Developer Pack on Windows 10 to get the targeting pack installed so you can select the new Framework version in your project properties.
It supports 24 languages. You can see a full list here: Please note that ENU is not on the table but is supported. Will the added information be exposed via the exception or in another way such that it will be possible to add it to logs?
Many windows 7 computers still run with. With the new DataAnnotation Localization support, how do you do disambiguation? Not all languages have the exact same language rules as English.
The new error message localization feature leverages provider pattern to enable developer to put the localized the message into different data store, e.
The developer needs to provide the localized message. You can view more information on. We also need to maintain such projects and would like to update them.
Can I install 4. There should be no need for any custom code to show the keyboard. You need Windows 10 Anniversay Edition and you need to have the OS in Tablet Mode or have the option to show the keyboard when not in tablet mode turned on.
With those conditions met, WPF will automatically show the keyboard when a control is focused via touch or stylus. I have another question.
Is any way to disable automatic showing system touch keyboard in WPF for instance in case I want have own keyboard independent of various versions of Windows?
Why WPF behaviour is different than in universal app? Are these corrections now in the new. I was confused about the long path context switch.
I think you meant to say opt-out: Never mind, I was confused because example set false. Kind of a double negative boolean.
For this particular feature opting without moving your TFM forward is more common than usual I think. I go into more detail in my blog:. Nothing except narrow vision of your pathetic architects.
Who cares NOW you remove that limit? Because that stuff had to be done 15 years ago! Check it out at https: All paths to files should work e.
For pipes you need to go through System. Pipes as FileStream has a specific check for handle type. Specifically because I want to allow not using CreateFile directly without depending on custom.
NET classes for things like mailslots. You can add your comments to my CoreFx PR at https: I have installed the dev pack and uninstalled it and re-installed it but it does not show up inside VS.
Also I cannot find any trace of 4. I really looking forward to the long file path support. Hi, I installed Windows 10 Aniversary update before Framework 4.
Any help would be great! You need to install the 4. See the Download Now section at the top of this page. Installing the developer pack does not help.
I installed the developer pack and the framework does not show up in VS. I repaired, I re-installed. Nothing I am able to do, aside from install a new copy of Visual studio, will make it appear inside VS.
I have targetted new WPF application on 4. Have I do something to get this feature working? But I have noticed that desktop app is not moved when keyboard cover input!
Older Windows versions have worked better. I was unaware there was an ask for this. New work starts in CoreFx on GitHub first- if you could open an issue there it would be great.
You can assign it to me. NET framework update breaks numerous running WPF applications due to the removal of the MemoryPressure framework class, often used to work around a serious WPF design flaw which, gratefully, was itself fixed in 4.
Which means, of course, that upgrading to Windows Anniversary Edition with 4. Anyone want to explain why my prior comment on this from yesterday morning has not shown up yet?
This is a serious, serious issue, and not the first time the in-place upgrades to. NET have caused us grief. Ah, probably not censorship, sorry.
I had a link in my post yesterday, probably got eaten by the spam filter. Thanks for reporting this issue to us. We are investigating and will update this thread when we have more to share.
I have reported this on Connect:. EXE Faulting module path: Faulting package-relative application ID:. Please respond on my blog where you also asked this question.
Will I be able to access the added information of NullReferenceException programmatically? A website server that provided by AppHarbor.
I just installed 4. I installed the developer pack and restarted VS; I even re-booted. This is easy to say, but users even do not notice when they exceed this lenght, they even do not know about this Limitation at all because it is ridiculous and something of the DOS — ies , and they definitely do exceed the path lenght — and loose data.
This Limitation also exists on Windows Servers, and in my Company much data was lost because of exceeding the Limitation by users.
Even IT departments sometimes are not aware. Why was this very fundamental and serious Limitation not addressed with e. Windows or earlier? Thanks to Jeremy Kuhne for saying that the summer update of Windows 10 now resolves this.
It would have been better to say that it hits developer scenarios much more frequently than consumer at this point in time.
We are aware, however, that the typical end user will hit this more often as they continue to accumulate files notably pictures. We absolutely want to see the issue resolved for everyone in the entire ecosystem- there is a lot more work still to be done to make this happen.
There were a variety of mitigations that have been done over the years for long paths, but they do only go so far. As years ago the need was not as pressing it was harder to argue for the investment needed beyond mitigations.
A lot of things changed over the past few years to help push this issue over the edge. I discussed some of what went into that in a recent.
I have installed the update successfully in a Windows 8 Enterprise 64bits. Support for Windows 8 has ended on January 12, I guess this is the reason that Windows 8 is not included in the Supported Opreating System.
Mario Vernari A bunch of good news! Does the new feature shift the viewport according to the actual useful area?
