e/Standard Gauge (toy trains)

Information
has gloss	eng: Standard Gauge was originally an effort by Lionel Corporation to corner the U.S. model railroading market of in the early years of the 20th century. Lionel standardized its offerings on three-rail track with a gauge of 2 1/8 in (54 mm) between the outer rails, making it incompatible with Gauge 2 offerings from European manufacturers. Lionel then registered a trademark on Standard Gauge. Other American companies followed Lionels lead, standardizing on Lionels new standard but calling it Wide gauge in order to avoid infringing on Lionel's trademark.
