In the context of transportation, 'deadhead' refers to the act of moving a piece of transportation equipment, such as a bus, train, or truck, when it is not carrying a paying load (either people or freight). It also extends to describe a nonpaid trip or someone who uses a service without paying.
A timetable is a tabular statement of the times at which certain events occur, often used for schedules of public transportation such as trains and airlines, as well as for predicting natural events like high and low tides.
