How to Make a Screen Shot
From TrainzOnline
Making screen shots (creating an image of what is shown on the screen) has changed through the various Trainz versions. The methods described here apply to TRS2019 and TrainzPlus. Screen shots have a number of uses in Trainz beyond just preserving an image of a part of your route for your enjoyment. Routes can have a thumbnail image, used as the 'preview' image on the Download Station as well as in Content Manager, and as a prominent display when a route is selected in Surveyor (see: HowTo: Thumbnail and Preview Images).
