Question: 1 / 400

What does the term 'dynamometer' refer to in rail transport?

A tool used for measuring distances

A device used to measure the force exerted by a train during its operation

The term 'dynamometer' refers specifically to a device used to measure the force exerted by a train during its operation. This measurement is crucial for assessing the performance and efficiency of locomotives and rail cars. By quantifying the pull or push force, a dynamometer assists engineers and conductors in understanding how well the train is performing under various conditions, which can influence operational decisions such as load adjustments and maintenance performance checks.

The other options relate to different aspects of rail transport. Tools for measuring distances, tracking train movements, and monitoring train speed serve important roles but do not encompass the specific function of a dynamometer. Hence, the focus on force measurement distinctly identifies the purpose of the dynamometer in rail operations.
