I would like to thank Charles Dockstader for this brilliant collection of valve gear simulations. He has created a fully graphically animated valve gear simulations, which can be customized with input data.  I have created separate installers for each valve type, as well as the option of downloading the entire suite (last on the list).  You can also view the valve gear operation with simulated steam and sound.  Features such as reversing and speed can also be adjusted on-the-fly.  Zoom right into the valve gear to see the detail and timing methods used by the gear. This software is a must for any steam or live steam enthusiast - fantastic stuff.  Please note that this software is neither supported by Charles or myself.
