In the UK, the person with ultimate responsibility for operation of a train is usually described as the Guard. The term 'guard' is derived from the days of stagecoaches. Until the later part of the 20th Century, Guards on passenger trains in these countries did not have routine responsibilities for ticket inspection or sale. Their jobs focused more on safe operation of their trains, timekeeping and handling parcels and other consignments. In recent years, passenger train Guards have been assigned more responsibility for on-train revenue collection and ticket inspection. When the Guard has a significant customer contact role, the position is usually classified as Conductor-Guard or Conductor.
