The '''Saxon Class XX <math>\textstyle \mathfrak{H}</math><math>\textstyle \mathfrak{V}</math>''' were German eight-coupled [[express train]], tender locomotives built for the [[Royal Saxon State Railways]] (''Königlich Sächsische Staatseisenbahnen'') just after the [[First World War]]. The locomotives, which became known as the 'Pride of Saxony' (''Sachsenstolz'') were the first and only German express locomotives with a 2-8-2 [[wheel arrangement]] and, at the time of their appearance, were the largest express engines in the whole of Europe. In 1925, the [[Deutsche Reichsbahn]] grouped these locomotive into their '''DRG Class 19.0'''.
 
==History==
The XX HVs were the last Saxon express train locomotives and were the pinnacle of Saxon locomotive engineering. They were conceived primarily for heavy express train duties on the winding and hilly [[Dresden]] to [[Hof, Germany|Hof]] trunk route through the ''Mittelgebirge''.
 
Its design was related to the simultaneously developed 4-6-2 express locomotive [[Saxon XVIII H]], but unlike the latter it had a fourth [[coupled axle]] and a four-[[cylinder (locomotive)|cylinder]] [[compound locomotive|compound engine]]. Between 1918 and 1925 a total of 23 examples were manufactured by the [[Sächsische Maschinenfabrik]] in [[Chemnitz]].  
 
The locomotives were given new running numbers 19 001–023 by the [[Deutsche Reichsbahn-Gesellschaft]] in 1925. The engines built in 1922 were stationed initially in [[Stuttgart]]-Rosenstein, those built in 1923 at [[Frankfurt am Main]]. From 1925 all 23 locomotives were homed in the Saxon [[locomotive depots]] (''Bahnbetriebswerken'' or ''Bw'') of [[Dresden]]-Altstadt and [[Reichenbach (Vogtland)|Reichenbach/Vogtl.]].
 
The engines fully met the requirements of a ''Mittelgebirge'' mountain locomotive, however its main disadvantage was its high coal consumption on the level. As a result the XX HV only worked the Dresden–Berlin line by exception.
 
Locomotive 19 021 was destroyed in the [[Second World War]] by a bomb, the remainder went into the [[Deutsche Reichsbahn (GDR)|Deutsche Reichsbahn]] in [[East Germany]] in 1945, but several were not used due to war damage. Until their retirement in the 1960s the locomotives continued to head express trains on the Dresden–Hof and Leipzig–Hof routes.
 
On the electrification of their main routes the locomotives were retired by 1967. Number 19 017 remains preserved as a non-operational museum locomotive at the [[Dresden Transport Museum]].
 
== Design features ==
The [[boiler]] was the largest of a German steam engine at the time the XX HV was brought into service and had exceptionally long heating tubes of 5.8 m in length. The grate was of almost square shape and had to be arranged above the frame due to its size. The boiler was used in the Saxon XVIII H as well, with only minor adjustments to decrease its weight which resulted in a heating area that was smaller by 10 m². The boiler was supplied with water through two [[feedwater pumps]] that were later replaced by one [[injector]] and a Knorr feed pump with preheater.
The steam engine was configured as a four-[[cylinder (locomotive)|cylinder]] compound. The high pressure cylinders sloped steeply between the [[locomotive frame|frame]] sides, the low pressure cylinders were located in the usual, horizontal position outside the frame. Both pairs of cylinders drove the second [[coupled axle]]. To control the supply to the low pressure cylinders there was a normal [[Walschaerts valve gear]] which also controlled the inside cylinders via pendulum levers. A special feature was the Lindner starting cock, already well-known on two-cylinder compounds, which could supply additional live steam to the low pressure cylinders when working at over 60%.
 
[[Westinghouse Air Brake Company|Westinghouse]] [[compressed-air brakes]] were installed for locomotive braking. This worked on one side only of all carrying and coupled wheels. Locomotives 19 012, 015, 017 and 022 were later fitted with [[Nikolaus Riggenbach|Riggenbach]] [[counter-pressure brakes]].
 
The vehicles were coupled to Saxon sä 2'2' T 31 [[tender (rail)|tenders]].
 
== Reconstruction ==
 
During 1963–1965 the locomotives fitted with a Riggenbach counter-pressure brake, nos. 19 015 and 19 022, were converted into trials locomotives by the [[VES-M Halle]] trials depot. They served as braking locomotives during performance trials.
 
The two engines were given new ''39 E'' boilers of the type designed for the [[DRG Class 03.10|03.10]], [[DR Class 39|39]] and [[DRG Class 41|41]]. The engine was originally heaving influenced by the dimensions of the [[turntable (rail)|turntables]] available in 1918 and was therefore not optimised for normal running. In addition to changes to the frame, it was modified with new 1000 mm diameter carrying wheels. This increased the overall wheelbase from 11,960&nbsp;mm to 12,100&nbsp;mm. New driver's cabs, ''Witte'' smoke deflectors, circular [[smokebox]] doors, a common cover for the [[steam dome]] and sand box as well as the arrangement of all pumps on a special mounting gave the engines a very different appearance. Number 19 015 was coupled to a 2'3 T 38 tender from H 45 024. In 1967 both locomotives were converted to oil firing.
 
In 1970 the two engines were renumbered to 04 0015 and 04 0022. In 1975/76 they were retired and scrapped.

After all, Word - Press is free, many of the enhancements for Word - Press like themes and plugins are also free, and there is plenty of free information online about how to use Word - Press. It allows Word - Press users to easily use HTML5 the element enable native video playback within the browser. These four plugins will make this effort easier and the sites run effectively as well as make other widgets added to a site easier to configure. This can be done by using a popular layout format and your unique Word - Press design can be achieved in other elements of the blog.

Saying that, despite the launch of Wordpress Express many months ago, there has still been no sign of a Wordpress video tutorial on offer UNTIL NOW. Note: at a first glance WP Mobile Pro themes do not appear to be glamorous or fancy. You've got invested a great cope of time developing and producing up the topic substance. These frequent updates have created menace in the task of optimization. Search engine optimization pleasant picture and solution links suggest you will have a much better adjust at gaining considerable natural site visitors.

There has been a huge increase in the number of developers releasing free premium Word - Press themes over the years. I have compiled a few tips on how you can start a food blog and hopefully the following information and tips can help you to get started on your food blogging creative journey. Some examples of its additional features include; code inserter (for use with adding Google Analytics, Adsense section targeting etc) Webmaster verification assistant, Link Mask Generator, Robots.

Website security has become a major concern among individuals all over the world. Mahatma Gandhi is known as one of the most prominent personalities and symbols of peace, non-violence and freedom.
