I'm loading up a Williams GG1
I found a RailKing File.
I'd like a premier file, as the wheels are pretty big on the Williams, I expect speed will be better.
Also, I expect lighting and sound will better.
There is 1 premier GG1 listed in the 2006 catalog, but I can't find a sound file, for it. 2005 and older are all 5V. The 5V file gave a critical error.
Anyone? I'd load the file from any Diesel or Electric that someone thought the speed would most accurate.
