A more thorough explanation:

Definition: Limbo time refers to the period when an employee is neither on duty nor off duty. This can occur when a railroad worker is waiting for transportation from a duty assignment to their final release location.

Example: A railroad worker has completed their shift and is waiting for transportation to take them back to their home location. During this time, they are not considered to be on duty, but they are also not yet off duty. This period of waiting is known as limbo time.

Explanation: The example illustrates how limbo time can occur in the context of a railroad worker's job. During this period, the worker is not actively working, but they are also not free to leave and go home. This can be a frustrating and uncertain time for the worker, as they are not sure when they will be able to leave and officially end their shift.
