Welcome to iRunTrains, my 3D model railroad simulation app for Mac, and co-developed with Onomaly for iPad and iPhone. The original Mac version (v0.7 from 2012) is no longer being updated, but is still available for download.

My new focus is the iRunTrain Web-App designed for PC web-browsers (Windows or Mac or Linux), and now also Virtual Reality (VR) headsets like the Meta Quest 3.
