`Reliable sources that use speeds below 110 mph include  and . The latter implies that this lower speed is only used in the U.S.; if this is true, we should state that, but not remove it just because it's not a worldwide standard. Also note  ``The Federal Railroad Administration (FRA) and U.S. Department of Transportation (DOT) has defined high-speed rail as self-guided intercity passenger ground transportation by steel wheel railroad that is time competitive with air and/or auto for travel markets in the approximate range of 100 to 500 miles (160 to 800 kilometers). This is a market-driven, performance-based definition of high-speed rail rather than a speed-based definition.`` and ``The international organization of railways, the Union Internationale Chemins de Fer (UIC) High-Speed Rail Task Force, has decided to use the plural word ``definitions`` for high-speed rail to reflect the fact that there can be no standard definition based on infrastructure, rolling stock, and operations.`` `
