|There is a long association between the railways and the mail. From the earliest lines, carriage by train proved an efficient and secure means of carrying parcels and letters of all
sorts. As W H Auden put it . . .
Letters of thanks, letters from banks,
Letters of joy from girl and boy,
Receipted bills and invitations
To inspect new stock or visit relations . . .
. . . Letters from uncles, cousins, and aunts,
Letters to Scotland from the South of France,
Letters of condolence to Highlands and Lowlands
