Welcome!

The principal purpose of the Operations Special Interest Group (OPSIG) is to discuss, develop and disseminate ways of operating model railroads to realistically emulate practices of the prototype. This includes sharing information on various methods of generating, moving and controlling traffic to heighten the feeling that our models are an active and integral part of the national rail transportation network, serving shippers and consignees throughout the nation. We also discuss and communicate information about the methods and procedures used by the real railroads and ways of most practically and realistically adapting them to the model world. So if you like to operate the railroad you've created, this is a place to learn more and find others with similar interests.

We publish a quarterly magazine, The Dispatcher's Office, which in addition to containing articles and information on railroad operations (both prototype and model), contains listings of operating layouts, sessions, and events that members are invited to attend. Back issues are available. In addition, the OPSIG web site serves as a clearinghouse for publicizing regional operating events and meetings, where layouts are open for guest operations. We also have a Facebook page and send out the Second Section email newsletter on a regular basis. 

What's New?

Additional features have been added to the web site:

  • When you log into the Members Only site, you will now see your subscription history, including the number of issues you have remaining on your current subscription.
  • The content related to the Virtual Meetups has been separated into multiple pages for better organization.
  • For each Dispatcher's Office starting in 2008, we have the covers and tables of contents digitized. You can see them in the Issue Index and in the Dispatcher's Office Online page.
  • The new Member Directory is available in the Members Only section of the site. Display of the information is controlled by the two settings in the member profile editor.

There are a number of features being redesigned to allow for easier maintenance:

  • Event Calendar - all entries will be tied to a member's information so they can be updated by that member at any time.
  • Call Board - we'll be merging your user profile information with what's on the call board so that you only have one place to update that information.
  • Membership Orders/Renewals - we'll be integrating with PayPal directly so that your order/renewal is processed immediately without having to mail in a form. For people who still want to pay by check, we'll provide a stub to send with your check so that it's processed properly. However, your membership information will be maintained here.
