The model train simulator is not working correctly anymore. Is there a “BUG”? It worked perfect before.
Thx

and describe the problem in order I to provide help and solution for it.
Is there a way to ” Adjust ” Flex Track after laying or is it Delete & Replace?
Hello loren,
Yes, you can select already laid flex-track, then right-click over its end and select “Reshape” from the context menu – that will place the flex track in edit mode where its sections can be deleted one-by-one (using Backspace) and reshaped as needed.
