HO scale train layout plans are a favorite choice for model train enthusiasts because of its large selection of layouts, structures and rolling stock. When choosing a model train layout plan, there’s two variables that matter most.
The first one is the amount of space that’s available to construct your layout and second is the level of detail that you desire. HO layout plans are a wonderful middle ground scale between larger and smaller scales, and it allows you to fit a solid layout into a somewhat sized space.
Here’s top 5 HO scale train layouts plans for model train beginners and intermediates including the dimensions and area required for the benchwork that provide easy access to your model train layout from hard to reach spots.

This HO scale layout plan consists of a reverse loop layout track plan with double oval line tracks. Along side of the two reverse loops is a train station near the front of the layout and a small train yard in the back. It uses a C-track, which is excellent for both passenger and freight trains plus has ability for shunting and switching traffic types.
You’ll also notice that all of the R2 tracks in the HO scale reverse loop wiring match the minimum radius of 360mm and turn-out angles of 24.3°. This allows for a high degree of maneuverability and adds more enjoyment to the overall layout plan.
Also, the easements at the outset of curves, i.e., the starting track piece have a wider radius (R2) than the “primary” curve, which is one of the advantages of this HO scale reverse loop. It will help you slightly enhance the appearance of a train entering and exiting curves.
