Good Morning All
I do not have access to the Amazon release of Trainz, however it should still include the expanded manual that is included in the 'international' edition of Trainz. You can access this by clicking on the 'manual' icon on the launcher screen. The expanded manual is 241 pages (inc front cover), however it will not cover every little aspect of Trainz.
Due to the complexity of Trainz, and the different in physics, or function of objects, we simply cannot cover the entire functionality of Trainz in the manual. We cover only the basic functions in the 'standard' manual (about 60 pages from memory), and then cover the majority of the common functions in the expanded manual, including 6 pages describing CAB mode. These will only explain the controls, and the basic theories of driving. It will not tell you exactly how to drive a locomotive through session, as this will vary (this is a simulator, and requires some practice to get the hang of CAB driving).
I will, however, speak to the team to see if we can put a copy of the expanded manual online.
As to printing the manual, printing is becoming more expensive, and including a full printed manual requires larger packaging to handle it. No matter what, it will increase the cost, and quite substantially... The TRS2006 'limited edition' that I have here includes the expanded manual for this edition. The manual is as thick as a standard DVD case, being 1.5cm thick (approx 5/8inch). To include such a manual would require either a custom produced case (much more expensive than using standard, widely available, cases) or extra packaging (again, more expensive).
As to 'locking away' information... We have a copy of the standard TS12 manual available for download, albait on the Trainz iPad page (I will, however, drop a link in the helpdesk knowledgebase/downloads area to this). As above, I'll also speak to the team to see if we can put the expanded manual online as well. All other Trainz documentation that is publicly available is on the TrainzDev, which does not require a login.
The helpdesk does require a login, however this is to make it easier for both sides, particularly for the person contacting us. Namely, they can then login and check the status of their ticket. It also means that replies go to one ticket, making it far quicker for us to handle tickets (one area that causes delays for us is when we need to read through 3 or 4 separate tickets, possibly under different accounts, to get all of the information!).
Note, the forums (some sections only) are the only part of our website that requires a serial number to actually post, or access some of the sections. Of course, the online functions within Trainz itself (DLS, iTrainz/multiplayer, chat) do require a serial number, but these aren't information/support functions...
