The original game comes with some fifty items of rolling stock and 15 different locomotives in 38 liveries and you can expand your collection by creating your own models, downloading those created by others or purchasing official add on packs. 

The 'My Collection' module also provides relevant information about each piece of rolling stock and allows you to move a virtual camera around any item to get a full 3D view.

As the Trainz project expands, My Collection will be updated to incorporate more functionality and support the new features of additional modules.
