Richard Wilhelm Ferdinand von Helmholtz (28 September 1852 - 10 September 1934) was a German engineer and designer of steam locomotive
Steam locomotive
A steam locomotive is a railway locomotive that produces its power through a steam engine. These locomotives are fueled by burning some combustible material, usually coal, wood or oil, to produce steam in a boiler, which drives the steam engine...

 in Munich, where he soon rose to become head of the design bureau. In this capacity, he had a considerable influene on the destiny of the company for decades, especially after the retirement of Georg Krauss from the management n 1885. In the course of his career he worked on all the components making up a locomotive, including less conspicuous parts such as his development of a new type of sander.

In 1887 he conducted ground-breaking research into the behaviour of locomotives on curves. From this theoretical work a practical result ensued in 1888: the design of the Krauss-Helmholtz bogie
Krauss-Helmholtz bogie
A Krauss-Helmholtz bogie is a mechanism used on a steam locomotive, where a carrying axle is connected to a coupled axle via a lever such that when the carrying axle swings to the side on going round a curve, it causes the coupled axle to move sideways in the opposite direction...

, which saw widespread use on locomotives with carrying wheels
Carrying wheels
The carrying wheels on a steam locomotive are those wheels that are not driven, i.e. they are uncoupled and run freely, unlike coupled or driving wheels. They are also described as running wheels and their axle may be called a carrying axle. Carrying wheels are referred to as leading wheels if they...

Karl Gölsdorf
Karl Gölsdorf was an Austrian engineer and locomotive designer.-Early Life:Karl Gölsdorf was born on 8 June 1861 in Vienna, the son of Louis Adolf Gölsdorf. Even as a schoolboy he was introduced to locomotive design by his father, the chief mechanical engineer of the Imperial and Royal Southern...

, drew even wider-ranging conclusions from the work of Helmholtz and created a radially-sliding coupled axle, the so-called Gölsdorf axle

The Gölsdorf axle system is used on railway locomotives to achieve quiet running and low wear-and-tear when negotiating curves. It comprises a combination of fixed axles and axles that can slide radially, all within a single, rigid locomotive frame....

, which became a standard in the construction of locomotives.

Of the many locomotive classes designed under his direction, a few examples are given here:

  • In 1896 the Bavarian AA I, of which only one was built.
  • In 1897 the Bavarian D XII
    Bavarian D XII
    The Bavarian Class D XII steam locomotives were manufactured by the firm of Krauss from 1897 for the Royal Bavarian State Railways . Ninety six of them were procured for service on the stub lines running from Munich into the mountains, but in reality they were stationed in many large Bavarian...

  • In 1908 the Palatine P 5
    Palatine P 5
    The six-coupled P 5 of the Palatinate Railway was to replace the four-coupled locomotives in the Palatinate. They were given a leading Krauss-Helmholtz bogie and a trailing bogie in order to achieve satisfactory weight distribution....

     and Bavarian Pt3/6, which ran for almost 50 years.

In such a long and innovative career, the occasional mistake was to be expected. For example, the Palatine P 3.II which was built in 1900 and displayed at the 1900 World Exhibition in Paris

 locomotive with a dolly axle. This design did not acquit itself well; as early as 1902 the dolly axle was removed and the engine converted into a normal 2'B1' locomotive.

After his retirement, he remained connected to the world of locomotives. Blessed with an excellent memory well into old age, he occupied himself, partly as an author and partly as a publisher, with recording the historical development of the steam locomotive. He died on 10 September 1934 in Munich
