Design and function

A typical design consists of an arm, called the walking beam, that pivots seesaw-like on a base, which the passengers alternately push down and pull up to move the car.

An even simpler design is pushed by two or four people (called trolleymen), with hand brakes to stop the trolley. When the trolley slows down, two trolleymen jump off the trolley and push it till it picks up speed. Then they jump into the trolley again, and the cycle continues. The trolleymen take turns in pushing the trolley to maintain the speed and avoid fatigue. Four people were also required to safely lift the trolley off the rail tracks when a train approaches.

Rail tracks have a tendency to develop various defects, including cracks, loose packing etc., which may lead to accidents. The first rail inspections were done visually. Push trolley inspections formed a very important part of these visual inspections.
