Numerous industrial narrow-gauge lines were built for peat extraction, clay extraction for brickworks and construction sites. The dominant gauge for industrial lines was 700mm (2ft3+9⁄16in), contrary to the 600mm (1ft11+5⁄8in) gauge used in neighbouring countries.
The majority of the Dutch narrow-gauge railways were built as steam tram networks, predominantly with 750mm (2ft5+1⁄2in) and 1,067mm (3ft6in)track gauge.[1]
