The advantages of a virtual railroad simulation: club members may be many miles apart, the railroad and its equipment can be synchronized to a particular era, operation may be accomplished in real-time with the affects of real distances, the session can be paused and resumed at the groups convenience, and software driven operating session is more adaptable then typical model railroad layout. Sharing your latest model with the group has an exact equivalent in sharing a newly created 3d model, but with a 3d model each member can have their own copy where the cost of producing the model is only having the use of a computer with an internet connection.
