Which environmental condition can negatively impact traction system performance?

The performance of traction systems can be significantly affected by rain, snow, and ice. These weather conditions create a number of challenges for traction systems, including reduced wheel-to-rail adhesion. In the presence of moisture, such as rain, or particulates like snow and ice, the surface characteristics of the rail can change, leading to slippage and ineffective power transfer from the traction system to the track.

When snow accumulates on the tracks or when ice forms, it can create a slick surface, making it difficult for the wheels to maintain adequate grip. This not only hinders acceleration but can also affect braking performance and overall stability. Moreover, snow and ice might require additional measures, such as de-icing strategies or sand applications, to maintain traction, further complicating operations and potentially leading to safety concerns.

Other options, while they may impact overall operations, do not present the same uniform, significant risk to the traction system itself as adverse conditions involving water and ice do. Cloudy weather might not affect traction negatively, and while windy conditions can influence stability and operations, they typically do not directly impair traction. High temperatures can affect system components and efficiency, but they tend to be less critical concerning immediate traction performance compared to the impact of precipitation and
