Got the Steam Patch for the FEF 844 this morning , and immediately I can see some major improvements. First thing that caught my attention was the loco sounds, which are 100% better. The author on Facebook said there are some changes in the Steam patch that are in addition to the changes that were in the patch on this website. He has some instructions on the Facebook page if you have the original patch.
Here is what he posted on his Facebook Page I just copied and pasted his not here.
" The official patch for the FEF-3 has gone live ... it's a 197.4 MB download (to replace the entire package, including the manual).
This patch supersedes the one I posted at RWA in December, so if you did install that one, you should delete the unpacked folders (Audio, Particles, Preload, RailVehicles and System) in ..\RailWorks\Assets\Smokebox\UP FEF-3 Northern, leaving only the UP FEF-3 NorthernAssets.ap file (size 1,009,994 KB)."
