Three Rail Model Layout at the National City Depot

3-Rail Layout

The National City Depot hosts a O-Scale / Three-Rail model railroad exhibit that is available during Museum operating hours. Members bring their rolling stock to run on the multi-track layout and many of the trains are capable of sounds, smoke, and nighttime operation. There are even a few items along the tracks that can be operated by visitors.

"Kids" of all ages can enjoy this world in O-Scale - even the Senior Kids! You just need to be a "kid" at heart. As you will see, there are unique elements all around that proves the designers had some fun!

We operate a modulal layout having 3 looping rail lines along with a 4 track ladder yard and long siding. The layout is in racetrack racetrack form and slightly "L" shaped. There is TMCC, ZW and an MR power supplies available to the tracks.

Bring your own trains and give them a good run in an historic train depot! Lionel 3-Rail, MTH, K-Line or similar - analog or digital - will run on the layout. Sorry, we can't run smaller gauges like S, HO, or N.
