Im wondering as a beginner of scenairio editing, if I should, or is it easier to, CREATE an existing scenairio, or EDIT an existing scenairio? So far I havent had much luck with manipulating installed free add-on locos, havent really tried to use any add-on freight cars as of yet. I want to base the scenairio on CSX/Conrail freight operations. But again, I dont have a stereo-typical route for either road. (although Ive heard one or both is common on the Horse Shoe, yet the terrain is uncommon to what I am used to in west central Ohio) Anywho, I like AI traffic, and I want the driver train to be signaled to stop to wait on passing trains and such. My question is is there any video tutorials (youtube) on a "beginners guide to scenairio editing/creating? I searched on youtube and found nothing.
