TRS 22, build 115985 I dont have too many industries a few coal, Water and 2 or 3 others. I am currently adding the industries after a completed route although the route is about 50 miles long. My CPU usage was about 18% and Ram (32gb) was at 38% when I clicked the waybill menu option. this time the game CTD. I havent tried a test route with just 1 commodity but thats the next step.
If any one wants to know I am using a edited version of the Durango and Silverton Route 1885 v4 number of engines about 6 mostly at the roundhouse not active.
