Operating a model railroad in a prototypical manner is one of the many
great aspects of this hobby. Realistic operations is
something
that can be shared with other model railroaders. Operations
include setting up systems to simulate the movement of freight cars on
the railroad and some means of dispatching trains. The
Operations
Special Interest Group (OpSIG) is a great resource of information on
operating model railroads.
