I am currently working on a beautiful model of the Union Pacific FEF-3, 4-8-4 locomotive #844! It is an amazing model from what I have done so far. It is just super time consuming to create the steam locomotives as the animations and moving parts are very complicated.
I actually have had that model donated to me as well, so eventually I will add it as well! Like I said, the steam locomotives are tedious and super complex, so they take lots of time. So far I have UP #844 in game and working, I am fine tuning the piston and connecting rod movements as this one is more complex then the Berkshire
