Saechsischen 4-4-2 Locomotives in Germany


Class Details by Steve Llanso of Sweat House Media

Class X H1s / BR 14.3 (Locobase 8058)

In Locobase 3800, the compiler quoted information from R A S Hennessey [nsc.chelt@talk21.com], Atlantics maven, who notes: "There were 2 classes, X V and XH1. There were 15 X Vs, 18 XH1s, all built by Hartmann. The 'V' in the first class was usually rendered in gothic fraktur type; stood for Verbund = compound. My source (K E Maedel, Die Koniglich Sachsiche Staatseisenbahnen) gives plenty of data on the XVs, v little on the 2-cyl XH1s"

Christian Lindecke of Lokodex.de ([link], accessed 5 Jan 2007) and Wikipedia's article on the X H1s remedy that lack. (As does additional data from Albert H Bone, "Some Recent Designs of Locomotives for Service on Continental Railways", Cassier's Magazine, 1910, pp. 561-609. )

These superheated enlargements of the K Sachs Atlantics simplified the steam distribution, substituting two larger cylinders for the 4-cylinder, compound working of the XV. They also rolled out larger boilers and grates.

The result was a handsome engine that flaunted its high-speed aspirations by splitting the wind with a pointed smokebox shroud. Alas for the designers' pretensions, traffic on the Berlin-Dresden line soon outstripped the power of even this upgraded 4-4-2 and the class was soon displaced.

When the Deutsche Reichsbahn Geselleschaft took over operations in 1925, it placed the 17 remaining engines in Class 14 3, but retired them all in 1926-1929.


Class XV / BR 14.2 (Locobase 3800)

Information from R A S Hennessey [nsc.chelt@talk21.com], Atlantics maven, who notes: "There were 2 classes, X V and XH1. There were 15 X Vs, 18 XH1s, all built by Hartmann.

Data from the table presented on pages 370, 372 of the Groupe VI. - GTnie civil. - Moyens de transport. DeuxiFme partie. Classes 32 (Tome I), part of the series of Rapports du Jury Internationale of the Exposition Unverselle Internationale de 1900 Paris Exposition, hosted on the website of Le Conservatoire numTrique des Arts & MTtiers ([link], Accessed 21 August 2005).

Other data from home.t-online.de/home/kopka.manfred/stamp.htm disagree slightly on heating surface (1,730 sq ft), grate area (25.61 sq ft).
