The Dakota Southeastern Division (DSED) is a division of the National Model Railroad Association (NMRA) and its Thousand Lakes Region (TLR).  Any NMRA member that resides in the eastern portion of South Dakota or Lincoln, Pipestone and Rock counties in Minnesota is automatically a DSED member.

You do not have to own a model train layout (or even model trains) to belong to the DSED. The DSED has railroads in both N and HO-scale that we travel within the Greater Sioux Falls, SD area. Members can bring their own trains, or use other members trains (we share), to operate on any of the DSED displays at various events throughout the year. You only need an interest in model railroading. You are also welcome to join us for a few events before joining NMRA to check us out. Contact us for additional information.
