Shunting (rail)
sorting railway vehicles into complete trains (or the reverse)
Shunting, in railway operations, is the process of sorting items of rolling stock into complete trains, or the reverse. In the United States this activity is known as switching.
Motive power
Motive power is normally provided by a locomotive known as a shunter locomotive (in the UK) or switcher locomotive (in the US). Most shunter and switchers are now diesel-powered but steam or even electric locomotives have been used. Where locomotives could not be used (e.g. because of weight restrictions) shunting operations have in the past been effected by horses or capstans.
A railcar mover (also called a shunt vehicle in Australia, the UK, and in Canada, or the trademarks Trackmobile or ShuttleWagon) is a road–rail vehicle (capable of travelling on both roads and rail tracks) fitted with couplers for moving small numbers of railroad cars around in a rail siding or small yard.
Hazards
Coupling
The terms "shunter" and "switcher" are not only applied to locomotives but also to employees engaged on the ground with shunting/switching operations. The task of such personnel is particularly dangerous because not only is there the risk of being run over, but on some railway systems—particularly ones that use buffer-and-chain/screw coupling systems—the shunters have to get between the wagons/carriages in order to complete coupling and uncoupling. This was particularly so in the past.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Shunting (rail)”, the useful work is to connect “sorting railway vehicles into complete trains (or the reverse)” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 21, 2026. The linked authority identifier is Q1429051. The Library of Congress control number is sh85111051. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
