What does the Special Service Request Code MAXO mean?

The Special Service Request Code MAXO specifically signifies that the maximum occupancy has been exceeded in sleeping car accommodations. This code is crucial for managing the availability and comfort of passengers in sleeping cars. It serves as a warning that the allocated space for resting and sleeping arrangements has been filled beyond its safe or comfortable capacity, which implies that no additional passengers can be accommodated in those particular sleeping arrangements. Understanding this code is vital for ensuring that all passengers have appropriate accommodations when traveling, enhancing their overall experience and safety on board.

The other options revolve around different aspects of travel management or passenger services but do not accurately reflect what the MAXO code represents in the context of Amtrak's service codes.
