What does accommodation code VS represent in coach class?

The accommodation code VS in coach class signifies that the seating is reserved. This means that when a passenger books a ticket with this code, they are guaranteed a specific seat on the train. Reserved seating provides travelers with assurance and planning convenience, as they do not have to worry about seat availability upon boarding.

Unreserved seating would mean that passengers can sit in any open seat, which often leads to a more chaotic boarding experience and uncertainty about seating arrangements. An accessible bedroom typically refers to private accommodations that meet specific accessibility standards, which is separate from coach class accommodations. Finally, a wheelchair transfer seat is a feature designed to assist passengers with mobility issues, ensuring they have the necessary support during their journey, but it doesn't indicate reserved seating. Therefore, the choice that correctly identifies the meaning of the accommodation code VS is that it represents reserved seating.
