Heathrow Worldwide Distribution Centre
Template:Refimprove thumb Heathrow World Distribution Centre (HWDC) is a sorting office for international mail operated by Royal Mail. It is situated in Langley, near Slough, England and opened in 2003.<ref name="dailymail">Template:Cite news</ref>
All mail entering and leaving the United Kingdom is sorted at Heathrow World Distribution Centre under tight aviation security standards, following the closure of all other international mail handling facilities in the UK. Not all mail handled at HWDC arrives by air, as road vehicles that formerly arrived in the UK by ferry at Dover, or container ship at Southampton now extend their trip to HWDC by road, instead of entering the Royal Mail network at (now defunct) offices of exchange situated nearest the ports. Outbound mail will usually leave the country by aircraft from the nearby Heathrow Airport.
Sorting & despatch process
HWDC is one of the most automated postal centres in Europe, and the site covers 100,000 square metres.
Automated conveyor systems transport trays of mail to automated mail processing equipment and manual or special handling workstations. The conveyors read the bar code labels on the trays and then transport them to the desired destination. When the mail is sorted on the automated mail sortation equipment, the letter destination image is lifted by high speed optical cameras. Both inbound and outbound mail is then automatically sorted into groups.<ref name="dailymail" />
Mail which is departing by air transport is often conveyed by containers unique to airlines and/or fuselage shapes. Upon arrival, specialised floor conveyors manipulate awkwardly shaped containers to support their manual loading. Frequently used containers are stored on site in a specialised automated storage and retrieval system. The scheduling of container arrival, loading, and dispatch is sequenced with flight arrival and departures.Template:Citation needed
