COVID has thinned the ranks of vendors.

Links to these forms can be found to the left in the menu. Registrations and policy letters must be filled out completely. Send no money. Registrations will be placed on the list in the order received but placing in the show will be on a space available basis.

The show floor is brightly lit and laid out to make it possible to browse and shop without crowding. Access to vendors is easy, even at the busiest times of the day. Our vendors come from all over the eastern and Midwest US to make a wide variety of merchandise available, including model and toy trains, railroad memorabilia, parts and tools, custom modeling services (painting, decals, structures, etc.), and custom layout design.

As always the venue will feature a large number of operating layouts in a wide variety of scales, from the tiny "N" scale to the glorious large-scale ("G" scale) garden layouts, and even bigger. A number of groups from around the country combine to build a huge N-Trak modular layout. There will be demonstrations by some of the best modelers in the nation including hands-on experience by local modelers, who will be available for questions and advice. There is something for everyone. Layout photographs from our show appear on many model railroad websites.

See you at the 45th Dayton Train Show on November 6-7, 2021.
