This SIG was formed independently in November of 1993 from within the National Association of S Gaugers membership for the purpose of forming an open line of communication among group members for the exchange of relevant prototype and model information.
The common interest of this SIG lies in the preference of modeling the modern diesel power and rolling stock of railroading as it is today and of those since merged roads of the immediate past in 'S' P:64 scale.
It also establishes a voice providing support and suggestion to the model railroad industry for the continual production of new modern S scale equipment.
Membership in this SIG includes the MPSM SIG newsletter, published at least six times a year. The cost of membership is $3.00. For more information contact the SIG coordinator:
