On elevated structure trackways, it is possible that:

Emergency alarm boxes may not be found on elevated structure trackways due to the specific design and accessibility considerations associated with these structures. In many elevated track systems, the infrastructure might not support the installation of alarm boxes as frequently as on ground-level tracks, leading to potential gaps in their availability.

It is important to recognize that the placement of emergency alarm boxes is often influenced by factors such as visibility, safety, and ease of access for both passengers and operators in case of emergencies. Elevated tracks can pose unique challenges, such as limited space, structural design limitations, and safety concerns that might hinder the efficient placement of these boxes.

Consequently, while the presence of alarm boxes is a necessary safety feature in many train operations, their distribution might vary based on the specific requirements and constraints of elevated structures, making it possible that many areas lack these essential emergency communication tools. This recognition can help in understanding operational safety protocols and the regulatory considerations necessary for effective emergency response planning on elevated track systems.
