Since 2006, the Tōkaidō Shinkansen's ATC-1A system has been superseded by ATC-NS. ATC-2: Used on the Tōhoku, Jōetsu and Nagano Shinkansen routes, it utilized 0, 30, 70, 110, 160, 210 and 240 km/h (0, 19, 43, 68, 99, 130 and 149 mph) trackside speed limits. In recent years, ATC-2 has been superseded by the digital DS-ATC.
All of NS's locomotives are equipped with Energy Management a computer system that provides real time data on the locomotive. The system can also control train speed and brake systems on board. The EM system allows the locatives to use less fuel and be more efficient. NS's final goal is completely autonomous operations of their trains.

A modern LF radio-controlled clock. A radio clock or radio-controlled clock (RCC), and often colloquially (and incorrectly [1]) referred to as an "atomic clock", is a type of quartz clock or watch that is automatically synchronized to a time code transmitted by a radio transmitter connected to a time standard such as an atomic clock.
For example, 12 o'clock means directly ahead, 3 o'clock means directly to the right, 6 o'clock means directly behind, and 9 o'clock means directly to the left. The clock system is not confined to transportation. It has general application to circumstances in which the location of one object with respect to another must be systematized.
Air traffic control (ATC) is a service provided by ground-based air traffic controllers who direct aircraft on the ground and through a given section of controlled airspace, and can provide advisory services to aircraft in non-controlled airspace. The primary purpose of ATC is to prevent collisions, organize and expedite the flow of traffic in ...
A quantum clock is a type of atomic clock with laser cooled single ions confined together in an electromagnetic ion trap. Developed in 2010 by physicists at the U.S. National Institute of Standards and Technology , the clock was 37 times more precise than the then-existing international standard. [ 1 ]
