What is a common consequence of en route brake failure if not documented?

The most significant consequence of en route brake failure, particularly if it is not documented, is the heightened safety risks for both the crew and passengers. When brake issues occur and remain undocumented, it could lead to lack of awareness or preparation for future incidents, increasing the potential for accidents or mishaps. Adequate documentation ensures that all safety protocols are followed, necessary repairs are made, and preventive measures are implemented, thereby safeguarding lives during train operations. When brakes fail to respond effectively, it creates a situation where immediate stopping is compromised, which directly threatens the safety of everyone on board.

While increased fuel consumption and delayed train schedules are potential outcomes of various operational issues, the severity of safety risks in the context of brake failure takes precedence over logistical concerns or cost implications. The primary focus in railroad operations must always prioritize the safety and well-being of those involved.
