This is just what the title says it is...there are three in this set so you can produce multiple train cars. The 'A dynamometer is a measuring device that is used to measure force tension applications and weight or pull forces. They are used to determine the torque, force, speed, and power required to drive a motor, which can be measured by evaluating the torque and rotational speed simultaneously.'
