Managers (Bureaucrats) are the users that steer Indian Railways Wiki. They have authority in any disputes, and can approve large-scale changes to the wiki. As well as being full administrators, Managers can also promote other users to staff.
On Wikipedia, an admin is defined as a "trusted user". You should be aware that this might not be the case on Wikia. The requester of a wiki will be given admin access to that wiki on the Principle of First Trust. If a user later turns out to be irresponsible with the admin access, it may be removed by one of the wiki's bureaucrats at any time.
