Some countries used narrow gauge rail to prevent invasion forces from using their rail infrastructure against them.

It was mostly used on branch lines for cost reasons. not only is the hardware less expensive since you can use much lighter rails and sleepers and smaller rolling stock, but you can take sharper turns so you can avoid topographical obstructions instead of having to go through them.
