Current Projects & Upcoming Releases
Heart of Wales Line – First Time in Train Sim Classic!
SwTrains is proud to introduce the Heart of Wales Main Line, a brand-new addition to Train Sim Classic, marking the first time this iconic route has been featured in the simulator. Known for its breathtaking scenery and rural charm, this line offers a truly unique railway experience.
To ensure the highest level of accuracy, our experienced track team has been out on the route itself, gathering real-world references and data. Every station, track layout, and landmark is being carefully recreated to bring this beautiful line to life as authentically as possible.
