Balloon loop

A balloon loop, turning loop or reversing loop, allows a rail vehicle or train to reverse direction without having to shunt or stop. Balloon loops can be useful for passenger trains and freight trains.

Balloon loops are common in tram or streetcar systems. Many streetcars and trams use single-ended vehicles that have doors on only one side and must be turned at each end of the route, or else haul tarile'cars with no driver's cabin in the rear car.
