Marine vertical valve gear Programs

[Dan Rowe]

The thread on Pat's engine made me think of the article I wrote for "Steam in the Garden" about the programs by Charles Dockstader and Rainer Radow. Both the programs are free so the article I wrote is also free.

I am a Shay fan because it is really a marine vertical engine on a locomotive. Getting Dockstader's Stephenson program to work with a vertical engine with out rocker took me a bit of work. The article is the same engine running in both Radow and Docksteader which is a marine vertical engine with direct Stephenson gear and marine links which is all that Radow will do except a nonreversing engine.

The Dockstader file (dso) for outside Stephenson gear is attached. I have to find the program file for the Radow program I have a bunch of versions so I have to check for correct file to go with the article.

Edit here are the program links
