$\gamma}_{\text{e}}=\frac{{V}_{\text{i}}^{2}-{V}_{\text{t}}^{2}}{2l$

where*l* is the distance between the position of the train or vehicle at the moment of the operation of the brake control and its position when the final speed is attained;

*V*_{i} is the initial speed measured at the moment of operation of the control device for the brake;*V*_{t} is the final speed obtained at the end of the braking
