Little Amerricka is an amusement park located in Marshall, Wisconsin, United States. It features the 16 in gauge Whiskey River Railway, a 1/3 size rail road with over 3 miles (4.8 km) of track that begins at the amusement park and goes through trees, past the wildlife pond area, and across the Whiskey River. Passengers hear a whistle as they go through the tunnel, past the locomotive shops including roundhouse and turntable, over bridges and around a lake. Other attractions include 24 rides and an 18-hole miniature golf course.

Minimum-gauge railways have a gauge of most commonly 15 in, 400 mm, 16 in, 18 in, 19 in, 500 mm or 20 in. The notion of minimum-gauge railways was originally developed by estate railways and the French company of Decauville for light railways, trench railways, mining, and farming applications.
