National Rail Network
In United States railroading, the term national rail network, sometimes termed "U.S. rail network", refers to the entire network of interconnected standard gauge rail lines in North America. It does not include most subway or light rail lines. Federal Railroad Administration The Federal Railroad Administration (FRA) is an agency in the United States Department of Transportation (DOT). The agency was created by the Department of Transportation Act of 1966. The purpose of the FRA is to promulgate and enforce rail saf ... regulations require passenger cars used on the national rail network to be heavy and strong enough to protect riders in case of collision with freight trains.

Rail Transportation In The United States
Rail transportation in the United States consists primarily of freight shipments, with a well integrated network of standard gauge private freight railroads extending into Canada and Mexico. Passenger service is mainly mass transit and commuter rail in major cities. Intercity passenger service, once a large and vital part of the nation's passenger transportation network, plays a limited role as compared to transportation patterns in many other countries. The United States has the largest rail transport network size of any country in the world. The nation's earliest railroads were built in the 1820s and 1830s, primarily in New England and the Mid-Atlantic region. The Baltimore and Ohio Railroad, chartered in 1827, was the nation's first common carrier railroad. By 1850, an extensive railroad network had begun to take shape in the rapidly industrializing Northeastern United States and the Midwest, while relatively fewer railroads were constructed in the primarily agricultural S ...

Standard Gauge
A standard-gauge railway is a railway with a track gauge of . The standard gauge is also called Stephenson gauge (after George Stephenson), International gauge, UIC gauge, uniform gauge, normal gauge and European gauge in Europe, and SGR in East Africa. It is the most widely used track gauge around the world, with approximately 55% of the lines in the world using it. All high-speed rail lines use standard gauge except those in Russia, Finland, and Uzbekistan. The distance between the inside edges of the rails is defined to be 1435 mm except in the United States and on some heritage British lines, where it is defined in U.S. customary/Imperial units as exactly "four feet eight and one half inches" which is equivalent to 1435.1mm. History As railways developed and expanded, one of the key issues was the track gauge (the distance, or width, between the inner sides of the rails) to be used. Different railways used different gauges, and where rails of different gauge met – ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Federal Railroad Administration
The Federal Railroad Administration (FRA) is an agency in the United States Department of Transportation (DOT). The agency was created by the Department of Transportation Act of 1966. The purpose of the FRA is to promulgate and enforce rail safety regulations, administer railroad assistance programs, conduct research and development in support of improved railroad safety and national rail transportation policy, provide for the rehabilitation of Northeast Corridor rail passenger service, and consolidate government support of rail transportation activities. The FRA is one of ten agencies within DOT concerned with intermodal transportation. It operates through seven divisions under the offices of the Administrator and Deputy Administrator. These divisions are: Financial Management and Administration, Chief Counsel, Civil Rights, Public Affairs, Public Engagement, Railroad Policy and Development, and Safety. It has a staff of about 850.
