What does the acronym TOASTED stand for in context of restricted speed?

The acronym TOASTED in the context of restricted speed stands for "Hazards that require stopping." This refers to specific situations that a train dispatcher or operator must be aware of when assessing the conditions of the track and the environment around it. When a train is operating at restricted speed, it is crucial that it can stop within half its sight distance in case of an unexpected hazard.

Understanding TOASTED is essential for ensuring safety; these hazards may include obstructions on the tracks, work crews, or any other conditions that could pose a threat. Hence, being cognizant of these hazards enables safe travel and minimizes the risk of accidents.

Each of the other options, while relevant to railroad operations, does not encapsulate the full intent of the acronym in the context of restricted speed. Various track conditions and types of signals may certainly impact a train's operation but do not specifically address the direct need for stopping in potential hazard scenarios. Operational procedures involve broader guidelines but do not specifically relate to the immediate hazards indicated by TOASTED.
