Travelling Post OfficeIn 1838, the first Travelling Post Office in Britain, a converted horsebox on the Grand Junction Railway in which the mail could be sorted, left London for Birmingham. Its success led to a rapidly expanded system with specially-designed railway wagons added to passenger trains. In the late 19th century the TPOs were specially timed to coincide with the ships which carried foreign mail. In 1855, trains solely devoted to the carriage and sorting of mail were introduced. During the 1990s, railway service became less reliable than by road or inland air network. The last TPO trains ran on 9/10 Jan 2004.
