What does coasting help reduce during train operation?

Coasting is a technique used in train operation where the train is allowed to glide along the track without power, relying on its momentum. This method is particularly effective in reducing fuel consumption. By turning off the propulsion system and allowing the train to coast, operators can minimize the energy required to keep the train moving, leading to a more efficient use of fuel. This reduction in fuel consumption not only helps in lowering operational costs but is also beneficial for the environment, as it leads to decreased emissions.

While coasting may also indirectly impact other factors, such as noise reduction, travel time, and potential station delays, its primary and most significant advantage is the reduction in fuel consumption. This practice is applied during various scenarios, such as approaching a station or negotiating a gradual descent, where maintaining momentum is feasible without active propulsion.
