Underpull is a term that is predominantly used in the field of transportation, especially in connection with railways. It refers to a situation in which a locomotive or a train experiences a lower level of tractive effort or pulling power than is required to pull or move a load. In simpler terms, underpull occurs when the force exerted by the locomotive is not sufficient to overcome the resistance or drag experienced by the train.
Underpull can arise due to various factors such as adverse weather conditions, mechanical issues in the locomotive, excessive weight of the load being pulled, or gradients on the track. When underpull occurs, the train may struggle to maintain its speed or even come to a complete stop, causing delays or disruptions in the transportation network.
To counteract underpull, rail operators may undertake various measures. This can include using more powerful locomotives, redistributing the load within the train, employing multiple locomotives to work together to increase tractive effort, or reducing the weight of the load being pulled. These actions aim to ensure that the locomotive generates sufficient traction to overcome the resistance and maintain a steady pace.
In summary, underpull refers to a situation in which a locomotive or train lacks the necessary pulling power to move a load, often resulting in reduced speed, delays, or even a complete halt.
The word "underpull" is primarily used in the context of train or locomotive operations, referring to the act of applying less power to the engine than required. However, it is worth noting that "underpull" is not a commonly used term and may vary in meaning depending on the specific context.
Etymologically, the word "underpull" can be broken down into two parts: "under" and "pull".
The prefix "under-" in English often indicates a sense of insufficiency, inadequacy, or below a certain standard. It suggests something less than expected or required. For example, words like "undercooked", "underestimate", or "underperform" all convey the idea of falling below a desired level.
The word "pull", in this context, is related to the action of exerting force or drawing something towards oneself.
