Welcome to iRunTrains, my 3D model railroad simulation app for Mac, and co-developed with Onomaly for iPad and iPhone. You can think of iRunTrains as a virtual model train-set that lets you control the speed and direction of up to three trains on many included layouts. Operate and view your trains in a variety of fun ways, just like the real thing ... except track never gets dirty, motors never wear out, and you can play with it anywhere.

Although the original Mac version-0.7 from 2012 is no longer being updated, it is still available for download. My new focus is the iRunTrain Web-App, designed to run in any web-browser (Google Chrome recommended) on most modern laptop and desktop computers, of any type.
