What is a common consequence of an overheated bearing during transport?

An overheated bearing during transport can lead to several significant issues. When a bearing overheats, it often indicates that there is a problem that needs to be addressed, such as insufficient lubrication or excessive friction. This situation typically necessitates immediate repair to ensure safety and prevent further damage.

Moreover, the consequences of an overheated bearing can lead to potential train delays. If engineers or conductors notice signs of overheating, they must take necessary precautions, which might involve stopping the train, performing inspections, and possibly making repairs before continuing. Such actions can disrupt the schedule and lead to delays, impacting overall operations.

Thus, the correct choice captures the multi-faceted implications of an overheated bearing, emphasizing the need for immediate repair and the likelihood of delays, alongside highlighting that there are generally increased safety considerations such as a need to adjust speed limits to maintain safety.
