Recently, there has been an invasion of T:ANE/Trainz locomotives and trains into the Steam store.
Also, a ready-to-run " light" version of T:ANE is being offered, that doesn't come with any creative tools, just the routes and trains: Trainz Driver 2016

Finally, according the N3V, the remaining Trainz 12 content, including Mojave Sub, Wilmington-Philadelphia NEC and the excellent Eastern European trains and routes are being ported to T:ANE/TzDr2016. Note that these routes are ported only, not upgraded to T:ANE standards.
Apparently free to existing owners participating in the beta testing of T:ANE SP1?
Three new USA DLC have been announced as well, including a Kicking Horse Pass route that is probably equal to Canadian Mountain Pass from Railworks.
I got this from the N3V subscription list, I haven't found a web page with these announcements yet.
