How many compartments must utility boxes have at minimum according to the operational standards?

Utility boxes are critical components in the infrastructure of train operations, often utilized for housing electrical equipment, emergency tools, or other essential items necessary for safe train operation. The operational standards dictate a minimum number of compartments to ensure proper organization, accessibility, and safety.

Having a minimum of three compartments allows for optimal space management. This configuration enables the separation of different types of equipment or tools, reducing the risk of cross-contamination or damage. For instance, one compartment might be designated for electrical equipment, another for tools, and a third for safety gear. This clear categorization facilitates rapid access during emergencies or routine inspections, thus promoting efficiency and operational safety.

In contrast, configurations with fewer compartments, such as one or two, would not provide the necessary organization and could lead to clutter, confusion, or delays in accessing critical equipment.
