Positive Train Control
Positive train control (PTC) is a family of automatic train protection systems deployed in the United States. Most of the United States' national rail network mileage has a form of PTC. These systems are generally designed to check that trains are moving safely and to stop them when they are not. Positive train control restricts the train movement to an explicit allowance; movement is halted upon invalidation. A train operating under PTC receives a ''movement authority'' containing information about its location and where it is allowed to safely travel. PTC was installed and operational on 100% of the statutory-required trackage by December 29, 2020. Overview The American Railway Engineering and Maintenance-of-Way Association (AREMA) describes positive train control systems as having these primary functions: * Train separation or collision avoidance * Line speed enforcement * Temporary speed restriction enforcement * Rail worker wayside safety * Blind spot monitoring History ...

Cab Signalling
Cab signalling is a railroad, railway safety system that communicates track status and condition information to the cab (locomotive), cab, crew compartment or driver's compartment of a locomotive, railcar or multiple unit. The information is continually updated giving an easy to read display to the train driver or Railroad engineer, engine driver. The simplest systems display the trackside signal, while more sophisticated systems also display allowable speed, location of nearby trains, and dynamic information about the track ahead. Cab signals can also be part of a more comprehensive train protection system that can automatically apply the brakes stopping the train if the operator does not respond appropriately to a dangerous condition. The main purpose of a signal system is to enforce a safe separation between trains and to stop or slow trains in advance of a restrictive situation. The cab signal system is an improvement over the Railway signal, wayside signal system, where vi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unfunded Mandate
An unfunded mandate is a statute or regulation that requires any entity to perform certain actions, with no money provided for fulfilling the requirements. This can be imposed on state or local government, as well as private individuals or organizations. The key distinction is that the statute or regulation is not accompanied by funding to fulfill the requirement. An example in the United States, would be those federal mandates that induce "responsibility, action, procedure or anything else that is imposed by constitutional, administrative, executive, or judicial action" for state and local governments and/or the private sector. As of 1992, 172 federal mandates obliged state or local governments to fund programs to some extent.Dilger, Robert J., and Richard S. Beth. Unfunded Mandates Reform Act: History, Impact, and Issues.
