In Great Britain there existed a practice of naming steam railway locomotives. The names chosen covered many and varied subjects. However, a large number of those represented direct links with military personnel, regiments, squadrons, naval vessels, aircraft, battles and associated historic events. This publication looks specifically at the relevant steam locomotives which came into British Railway stock on 1 January 1948.

Memorably, the London, Midland & Scottish Railway named an express locomotive Patriot, as a memorial engine following on from a London & North Western Railway (LNWR) tradition. That name was then applied to a complete class of locomotives. In addition, a large number of the company's Jubilee class locomotives were given names with a military connection, as were a small number of Black Five class engines. Famously the majority of the much-admired Royal Scot class of engines carried names associated with the military in general and regimental names in particular. The Stanier 8F class, often referred to as The Engines of War were unnamed by the LMS. However, one of the class honoured the memory of a Victoria Cross holder, whilst the locomotive was in the UK and under the ownership of the War Department.

Many of the nameplates were adorned with ornate crests and badges.

Long after the demise of mainline steam, rescued nameplates are still much sort after collectors' items, which when offered for sale command high prices. This generously illustrated publication highlights the relevant steam locomotives at work around the railway network and explains the origins and social history surrounding their military names.
