railroad station in the US, while train station is used in both; trains have drivers (often called engine drivers) in the UK, while in America trains are driven by engineers; trains have guards in the UK and conductors in the US, though the latter is also common in the UK; a place where two tracks meet is called a set of points in the UK and a switch in the US; and a place where a road crosses a railway line at ground level is called a level crossing in the UK and a grade crossing or railroad crossing in America. In the UK, the term sleeper is used for the devices that bear the weight of the rails and are known as ties or crossties in the United States. In a rail context, sleeper (more often, sleeper car) would be understood in the US as a rail car with sleeping quarters for its passengers. The British term platform in the sense "The train is at Platform 1" would be known in the US by the term track, and used in the phrase "The train is on Track 1". The British term brake van or guard's van is a caboose in the US. The American English phrase "All aboard" when boarding a train is rarely used in the UK, and when the train reaches its final stop, in the UK the phrase used by rail personnel is "All change" while in the US it is "All out", though such announcements are uncommon in both regions. For sub-surface rail networks, while underground is commonly used in the UK, only the London Underground actually carries this name: the UK's only other such system, the smaller Glasgow Subway, was in fact the first to be called "subway". Nevertheless, both subway and metro are now more common in the US, varying by city: in Washington D.C., for example, metro is used, while in New York City subway is preferred. Another variation is the T in Boston. Television Traditionally, a show on British television would have referred to a light-entertainment program (BrE programme) with one or more performers and a participative audience, whereas in American television, the term is used for any type of program. British English traditionally referred to other types of program by their type, such as drama, serial etc., but the term show has now taken on the generalised American meaning. In
