📋 About This Mod
“Living Legend” FEF-3 No. 844
┃ PREFACE ┃
It is not a 100% replica of a steam locomotive in the real world.
We're still polishing up the release page....
By a stroke of serendipity, I partnered with LittleNiko36 to remaster the legendary FEF-3 steam locomotive. (Though I initially aimed to develop the GS-4, LittleNiko36 had already completed the bulk of that project.) In my spare time, I crafted my very first American steam locomotive: the iconic Union Pacific FEF-3 No. 844—a masterpiece that reignited my passion for the steam era’s awe-inspiring grandeur.
I’m thrilled to collaborate with LittleNiko36 on this endeavor, fostering deeper creative synergy within our modding community. Together, we’re delivering unprecedented power and majestic presence to players worldwide, transforming how enthusiasts experience historical railroading. This project isn’t just a remaster—it’s a leap forward, elevating community-driven mods into a new golden age of immersion and artistry.
FEF-3 No. 844 Steam Locomotives
The Union Pacific Railroad’s iconic FEF-3 steam locomotive—a masterpiece built in 1944 by American Locomotive Company (ALCO) as part of a 4-8-4 wheel arrangement series. Among these, the legendary No. 844 remains in active operation today as a fully preserved historical exhibit, embodying the enduring legacy of America’s steam era.
This mod features two meticulously crafted FEF-3 locomotives, each offering two distinct paint schemes for seamless customization. Choose your preferred livery to experience the power and elegance of these engineering marvels in your virtual railroading journey.
