I know that your plates are already overflowing with requests, but please consider this one as well -- even if it gets placed at the end of the list. The manuals for all TSW routes are just plain inadequate. For example, several of the engines now available to us feature operations screens on which a number of functions actually work, but none of the manuals even mention them, much less provide illustrated descriptions of what they do. Here and there, a tutorial or a scenario includes sketchy instructions for using cab controls, both manual and electronic, but only in a very superficial manner. Again, providing this information is less important than developing new routes, scenarios, sessions, etc.; but this information would, in my opinion, add a lot to understanding, appreciating, and enjoying TSW.
