Rolling stock, edit session parameters, driver commands and interactive industry settings were saved with the session file. For example the track, groundtextures, trees and other scenery objects were saved with the route as were triggers and trackmarks. long time users of Trainz are aware that in the past when you saved in surveyor certain items were saved with the route file and certain other items were saved with the session file.

There's a good introduction to the new concept of layers on Auran's forum at Layers Quickstart Guide. Trainz 2009 SP4 is barely different than Trainz 2010's initial releases, but the installed content varies, and TS2010 continued with the never ending succession of new improvements. English is virtually always first as a de facto International, if not Universal language. Initial Trainz retail releases (and build 'tracks') lag in time and feature somewhat because of the translation needs to support global languages of the user base. Layers started in this case, in Trainz TS2009 SP4 (Service Pack 4, so build=44653, post-TRS2009, Service Pack 3=build 40040)- where build 40040 was considered a stable product and all languages build paths converged to that state with SP3 installed. Layers are a new feature, one good example of the incremental improvements put into the game engine between major Trainz retail versions, by the programmers as they evolve the software. In most respects, TS2010 is best considered the belated final release of advanced and user community requested features promised in TS2009: World Builder Edition, and it should be noted that the TS10 releases, for the most part, share the same 'technology tracking level'-the Trainz-build (TB) or version numbers. The formally named Trainz Simulator 2010: Engineers Edition by any of its more commonly seen shorthand 'use notations' was a 'continuation' building upon changes made in the transitional release TS2009, and going one step further using the Windows 32 bit computing technology of multi-core CPUs and further supporting advances in graphics cards while maintaining backwards data model compatibility ( Compatibility mode) on the route and sessions data types on the one hand or the initial implementations of next generation technologies later seen better exploited in TS2012 such as Trainz Multiplayer, Speedtrees, and the Native mode data model changes that thereafter prevent backwards compatibility to older-earlier Trainz releases.
