With a BETA arriving in December 2016, and full release early in 2017, TSW represents a major step forward for railroad simulations. Based on the Unreal gaming engine, TSW promises much better realism, both in look and operation, allowing 3D artists to once again push back the envelope of create mastery. Everything is new again!
And it won't be quick. No development tools are slated to be released with the BETA, and likely not the first release. Unreal is a vast suite of tools, and no backward compatibility is planned. This really frees up what is possible, but it also lengthens the time that new content will appear for TSW.
With this September 2016 announcement, we are officially ending development of Panamint Crossing for the existing TrainSimulator product. The route is now freely available to anyone who wants it, and you have our blessings to do anything you want with it, assets and all.
We have another route planned in addition to Panamint Crossing, one which pushes the LOD horizon just as far as the basin and range vistas of America's southwest. But we'll keep it under our big ugly hats until we have a demonstration ready. If you live in Michigan, you are going to just squeal!
Here's a peek at the new sim (click to enlarge):
Many thanks again to the TS community. Our brightest days are ahead!
