A cab unit and a carbody unit are body styles of locomotives in railroad terminology. While closely related, they are not exactly the same.
With both body styles, a bridge-truss design framework is used to make the body a structural element of the locomotive. The body rises above the locomotive frame, and extends the full width of the locomotive and along its length. The service walkways are inside the body.
This configuration gives a cab or carbody unit poor rear visibility compared with a hood unit. For that reason, cab or carbody units are mostly used in situations where rear visibility is not important, such as power for through freight and passenger trains. Cab and carbody units are also more aerodynamic than hood units, and pulled many of the streamliner trains.

“During the Suffragette revolt of 1913 I ... [urged] that what was needed was not the vote, but a constitutional amendment enacting that all representative bodies shall consist of women and men in equal numbers, whether elected or nominated or coopted or registered or picked up in the street like a coroner’s jury. In the case of elected bodies the only way of effecting this is by the Coupled Vote. The representative unit must not be a man or a woman but a man and a woman.”
—George Bernard Shaw (1856–1950)
