London, Midland & Scottish Railway workers beside the "Irish Mail" at Holyhead station, Anglesey, 1931. The Irish Mail is the oldest named train in the world and has been running since 1848. It runs between London Euston and Holyhead where it connects to a ferry which takes the mail to Dublin. The train also carried passengers wishing to travel from London to Dublin. The worker on the left is handing over a watch. The Irish Mail ran strictly to Greenwich Mean Time and the train carried a watch that had been set at the Greenwich observatory to ensure the train ran to the correct time. The watch was handed over in Holyhead, taken on the ferry to Dublin and brought back again the next day! This ceremony took place from 1848 to 1939.
