Cant seem to find way to preserve train orders from one session to the next. Thought a session would only concern itself with trains on the route and their orders but discovered after deleting previous session that route tracks also were deleted leaving the trains resting on ballast with no tracks. Two days work blown. Don't understand layer concept. Dont understand why Autosave should duplicate itself, surely two files with same name should be flagged for attention. Don't understand why in driver a station is suspended mid air while in build it returns to proper placement. I am rapidly falling out of love with Trainz 2012 and unlikely to purchase future versions if one cannot build a route, test it and decorate it without being frustrated by a less than intuitive methods learned from previous versions.
