A Travelling Post Office was a type of mail train used in Great Britain and Ireland where the post was sorted en route. The last TPO services were ended on 9 January 2004, with the carriages used sold for scrap or to preservation societies.
Following an agreement in 1830, made between the General Post Office and the Liverpool and Manchester Railway, mail had been carried by train in Great Britain, between Liverpool and Manchester, via the L&MR. The passing of the Railways Act 1838 required railway companies to carry mail, by ordinary or special trains, as required by the Postmaster General; however, this act did not set the charges for such services. These special trains eventually became TPOs. TPOs were employed in many British Commonwealth countries; and the Army Post Office had its own TPOs. TPOs were equipped with letter boxes so that mail could be posted whilst the train stood at a station. The post-marks from TPOs are valued by philatelists.
History
Mail was first sorted on a moving train in January 1838, in a converted horse-box, on England'sGrand Junction Railway. It was carried out at the suggestion of Frederick Karstadt, a General Post Office surveyor. Karstadt's son was one of two mail clerks who did the sorting. In 1845 the service was extended via Derby to Newcastle upon Tyne by the Midland Railway; and soon after reached Scotland. The first special postal train was operated by the Great Western Railway between London and Bristol. The inaugural train ran on 1 February 1855, leaving Paddington station at 20:46, and arriving at Bristol at 00:30. In 1866, apparatus for picking up and setting down mailbags without stopping was installed at Slough and Maidenhead. This had first been patented in 1838 by Nathaniel Worsdell, first deputy mayor of Crewe, and carriage and wagon superintendent at Crewe Works. In 1963 there were 49 mail trains, with one to five TPOs attached to passenger trains, and complete TPO trains between London and Aberdeen and Penzance. The last mail drop from a moving train using automatic apparatus was carried out on 4 October 1971 at a location just north of Penrith although there were over 40 TPOs still running, transfer of items was only carried out at stations after this date.
Post-privatisation of British Rail
After the privatisation of British Rail in the mid 1990s, British TPOs were operated by Rail Express Systems and its successor EWS. Royal Mail decided to suspend all transportation of mail by rail in 2003. The last TPO services went out on the night of 9 January 2004, ending the sorting of mail on trains in the UK. However, Royal Mail did restore the movement of some already-sorted letters by rail in time for the Christmas season that year, contracting with EWS's competitor GB Railfreight to resume bulk transfer services along the West Coast Main Line between its mail terminals at London, Warrington and Glasgow using the dedicated Class 325electric multiple units that had been in operation since 1996. In 2009 the contract for these mail trains was transferred to EWS's successor DB Schenker Rail. For flexibility Royal Mail had preserved rail access to its distribution centres on Tyneside and at Tonbridge in Kent, and did occasionally send mail trains to Low Fell, for example when Newcastle Airport was closed by snow. In June 2013, a regular service resumed from Low Fell.
Early TPOs began to appear on Irish trains in 1855, though general post-carrying vehicles had been around since the early days of the Dublin and Kingstown Railway. In 1958, Coras Iompair Eireann built four modern TPOs for Department of Posts and Telegraphs at their Inchicore Works. Some time before their withdrawal it had been decided that two would be dedicated to use on the Cork Mail and two to the Galway Mail, both of which originated from Connolly station in Dublin. The movement of post by rail in Ireland ended in 1992. Two of the 1958-built TPOs survived into preservation- 2977 of the Cork Mails and 2978 of the Galway Mails. Both are at the Downpatrick and County Down Railway, who own 2978, whilst 2977 is still owned by An Post.
Preservation
Several Royal Mail TPOs have been preserved along with stowage vans and general utility vans. Only one PCV remains, currently at the Mid-Norfolk Railway. At these preserved lines you can see the TPOs performing a live drop off/pick up from a preserved line side apparatus. The Great Central Railway and the Nene Valley Railway are leading this endeavour with many weekends devoted to Mail by Rail. Other lines are following in their wake.
TPO vehicles
TPOs were formed of several different types of vehicle:
