The station is between Mount Pleasant Mail Centre and Whitechapel Eastern District Post Office, and is situated at the south end of Liverpool Street under the Great Eastern Hotel. It opened in December 1927; lifts on either side of the station as well as chutes enabled the transfer of mail to and from the main station. Two parcel and letter bag conveyors were connected to platforms 10 and 11 (currently used by Greater Anglia); postal traffic reached 10,000 bags daily in the 1930s, with 690 Post Office services calling. The system was discontinued in 2003.
