The following videos have been constructed to view Stephenson’s and Walschaerts’ gears in motion through 360 degrees and later versions of Windows Media will allow continuous rotation.
The STEPHENSON link motion is the GWR set applied to the two outside cylinder locomotives of several Classes and is one of the finest of such applications.
Unlike Stephenson’s gear WALSCHAERTS’ is usually an outside application and may appear more familiar. This example is a BR Class 4.
