The compartment aboard a starship that holds a transporter platform and its control console, where landing parties leave and visitors are received.
A transporter room contains the raised platform on which people and cargo are beamed to and from a ship, together with the console from which an operator controls the process. Large ships have several. It also serves as the place where a ship receives guests, with senior officers lining up in dress uniform to greet ambassadors as they materialise.
On the original Enterprise the console is usually worked by Scott or Lieutenant Kyle, and the room is the setting for the accident that splits Kirk in two in The Enemy Within. On the Enterprise-D Miles O'Brien is the regular chief in Transporter Room 3 before his move to Deep Space 9.
Many stories begin or turn here, among them Realm of Fear, in which Reginald Barclay must face his dread of the platform, and Rascals, in which four of the crew arrive on it as children.
