its variety and availability. HO Scale trains are 1:160 scale. You can
build a small layout on a sheet of 3x6 plywood on up to a basement size
model railroad empire!

HO Scale is a great way to get started in the model train hobby. There
are many ready to run starter sets that can easily be expanded to a
much larger layout. There are many details and accessories available to
allow you to build a railroad based in the 1950's or even a
contemporary modern day railroad!
