The pictures at right show past layout scenes


The Tri-City Model Railroaders (TCMR) welcome you to their website and hope that its resources and information will be useful in your pursuit of this amazing hobby of model railroading. TCMR members are part of the Pacific Northwest Region’s 5th Division of the National Model Railroad Association. 

JUST NEED TO CONTACT US? See information at bottom of this page.


*** Effective immediately, our facility (11 West Kennewick Avenue in the City of Kennewick) will be closed to the public for an indefinite period of time. This closure will be re-evaluated in a couple of months and a follow-up announcement may be made, depending on the latest health requirements.

The organization’s modular layout, as used at various venues between 1990 and 2020, is no longer available. If you would like to see a brief video on the modular layout’s earlier operations, just click here.

The “Progress” section of this website contains photos of the new layout now under construction and as discussed below. Access to the layout’s design and schematic drawings are also provided below. To view initial train operations during a previous Saturday session, click here.

The pictures above (at left) show the upgraded building facade and a recently added mural to the West exterior wall done by local artist, Jared Johnson. The mural scenes depict the original swing bridge over the Columbia River, the Kennewick Hotel, a teacher who traversed the bridge system for her work schedule, original strawberry crops and local workers.


When our organization’s permanent site is open to the public, a small retail operation is available and the new layout can be seen. Items for sale include books, various structures, rolling stock pieces, detail parts, kits, T-shirts, mugs and other related (model) railroad items. All sales are on a final, cash-only basis. Also, please remember that we are a small organization and dependent on volunteer members being available for the above schedule.


Layout development is continuing. Track work is complete for both Pasco and Kennewick areas on Level B as well as for the Wallula and staging areas on Level A. Continuous train operations can now occur on both Levels A and B in conjunction with helix tracks. 

Trackwork to Levels C and D within both helices is complete and track roadbed has been laid for the Toppenish and Yakima areas as well as for Union Gap and surrounding branchline service areas. Roadbed is also being laid for the Level D thru the Cascade Mountain area including Stampede Tunnel. Once the Level D trackwork is complete, major scenery development is expected to begin.

The special modeled bridge structure for our future Columbia River scene has been completed and delivered by renown model builder, Wayne Wesolowski. The bridge will be on display at a future date. 

Our design plan for this HO-scale layout reflects a hybrid “mushroom” configuration to maximize the size of the exhibit. To view the four levels of the layout design, click on the appropriate links below. The “Elevation View” file provides a composite depiction of all levels while the Layout Schematic drawing gives a linear view of how the levels’ trackwork is interconnected.

Our work on the new layout continues to be dependent on increased funding. CAN YOU HELP US? See the “Donations” discussion below for more information.
