Her Majesty's Mails

The railway post-office proper, is now extended over nearly every considerable line of railway in the kingdom. It comprises a number of divisions or sections, named generally from the locality through which they extend, or the railway travelled over, as the Bangor and Leeds division, the Caledonian Railway post-office. The four principal or trunk mails, three of them being divided into two sections, are (1) the North-Western Railway post-office, travelling between London and Carlisle; (2) the Irish Mail, between London and Holyhead; (3) the Great Western, between London and Exeter; and (4) the Midland, between Bristol and Newcastle-on-Tyne. Most of these divisions have day- as well as night-mails running over them daily. Four trains a-day, being two in each direction, are therefore the usual proportion of mails on the chief lines of railway. As London is the heart of the postal system, so these four principal mails may be termed its main arteries, while as veins in the great system, there are a number of smaller divisions of the railway post-office that have not been enumerated. Again, at other parts or points not important or extensive enough for travelling offices, railway trains are arranged to wait the arrival of the trunk mails; and thus, to continue the figure, our letters--the life-blood of a nation's commerce and sociality--are conveyed to the remotest corners of the country.
