An observation car/carriage/coach is a type of railroad passenger car, generally operated in a passenger train as the rearmost carriage, with windows or a platform on the rear of the car for passengers' viewing pleasure. The cars were nearly universally removed from service on American railroads beginning in the 1950s as a cost-cutting measure in order to eliminate the need to "turn" the trains when operating out of stub-end terminals.

A whistle stop or whistle-stop tour is a style of political campaigning where the politician makes a series of brief appearances or speeches at a number of small towns over a short period of time.
