This list is for the promotion, discussion, exchange of technical data, model building construction advice and display of Interurban, Traction and Trolley prototypes, model photos and plans.

Historical data, modeling hints and JPEG photos of models both completed and in progress are encouraged. Photo attachments are once again allowed as of May 15, 2010.

This list primarily targets the serious modeler, interested in scratchbuilding, superdetailing and/or kitbashing reasonably accurate models, based upon a specific prototype, or logical prototype practice. However, all model railroaders and other interested parties are welcome. The long term goal of this list is to, hopefully, increase the popularity of "Traction" modeling to the general model railroad community.
