When a train has made a full brake application due to adverse event, or has lost its train air due to a defective valve (a "kicker"), or a broken air line or train separation. The train crew will normally declare that they are "in emergency" over the train radio, thus warning other trains and the dispatcher that there is a problem.
A train (from Old French trahiner, from Latin trahere, "to pull, to draw") [1] is a series of connected vehicles that run along a railway track and transport people or freight. Trains are typically pulled or pushed by locomotives (often known simply as "engines"), though some are self-propelled, such as multiple units or railcars .
Rail transport terms are a form of technical terminology applied to railways. Although many terms are uniform across different nations and companies, they are by no means universal, with differences often originating from parallel development of rail transport systems in different parts of the world, and in the national origins of the engineers and managers who built the inaugural rail ...
In some cases the term higher speed rail would sound incorrect to define a train travelling below a high speed since higher is greater than high. Therefore, the word higher speed rail would sound correct to refer to a train at a speed between 300 and 500 km/h (i.e. greater than the high speed of 200–300 km/h). [according to whom?]
A train is a connected series of rail vehicles that move along the track. Propulsion for the train is provided by a separate locomotive or from individual motors in self-propelled multiple units. Most trains carry a revenue load, although non-revenue cars exist for the railway's own use, such as for maintenance-of-way purposes.
A passenger train is a train used to transport people along a railroad line, as opposed to a freight train that carries goods. [1] [2] These trains may consist of unpowered passenger railroad cars (also known as coaches or carriages) hauled by one or more locomotives, or may be self-propelled; self propelled passenger trains are known as multiple units or railcars.

A passenger coach that is disconnected from a train without the train having to stop. While the train continued on its route, the slip coach would be guided and stopped by a guard on board using the coach's own brake mechanism. This practice was almost entirely limited to the United Kingdom and was discontinued in the 1960s. [23]: 339 [93] Spinner
