Two logos (or crests) were used during the period. The first logo (1948–1956) was the "Lion and Wheel" (sometimes nicknamed the "Cycling Lion"), showing a lion standing over a spoked wheel upon which the words "British Railways" were displayed. The second logo (1956–1965) featured a lion "holding" a wheel (which gave rise to the nickname "ferret and dartboard"), sitting in a crown, with the words "British" and "Railways" to left and right. (Passenger stock and certain diesel locomotives used a roundel variant, where the words "British Railways" were in a ring surrounding the crest.) From 1965, the BR Corporate Image and "Double Arrow" logo was adopted, but this logo was not applied to steam locomotives (except on the Vale of Rheidol line).
