The Ry-ops-industrialSIG list, (Ops-Ind) is the primary discussion list of the Operations SIG of the NMRA and the NMRA's Industries SIG.

The purpose of this list is to provide a forum for railway modellers to discuss railroad operations as well as to model industry practices and operations. Operations is a series of events that are required to complete a task. We expect this list to show how these tasks should be set out to accomplish your goal. Discussions will include, among other things, how best to simulate the operations of prototype railways and how to operate trains by Train Orders or Centralized Traffic Control. Computers or car cards (a manual car card waybill system)will be discussed.

Do you know how all the industries you model actually carry on day to day business? Where do typical raw materials come from to produce their products? Where do the finished products go? How are industry practices and railway operations linked? All of these questions are typical of what we plan to discuss on the Ops-Ind list.

The list is open to all who have an interest in simulating the operations of railways and industries on their layouts.
