A '''mixed-traffic locomotive''' is one designed to be capable of hauling both [[Engineering:Passenger train|passenger train]]s and [[Engineering:Freight train|freight train]]s.  The term is mostly used in the {{wipe|United Kingdom}} and those nations following British practice.

==Overview==
Mixed-traffic locomotives were common in the early years of railway development, but changing traffic patterns meant that later designs would tend to be more specialised, to haul the fastest passenger trains and the heaviest freight trains.

==Characteristics==
Driving wheel sizes were generally intermediate: larger than the small wheels of most freight locomotives, required to produce a high [[Physics:Tractive effort|tractive effort]] at low speeds, but smaller than the large wheels express passenger locomotives required to reach high speeds.

==Use of the term==
The term was generally only used for [[Engineering:Steam locomotive|steam locomotive]]s, since most of the first generations of British mainline diesel locomotives were equally capable of hauling both passenger and freight trains, specialised designs not appearing for many years.
