To us, this sounds like the script to a Two Ronnies‘ sketch, but presumably people wishing to travel on the York mail could work it out – or maybe end up in Edinburgh?!
“Considerable alterations will be made in about a month’s time, in the arrangements of the mails which pass through Stamford. The present ‘York mail’ will go northward by Northallerton, and not at all to York. Its time is to be still further accelerated, so that it will reach Edinburgh (394 miles) at six o’clock on the second evening, or in 46 hours after leaving the General Post office in London: its speed, therefore, must be more than ten miles an hour when travelling, or nine miles an hour including all stoppages. It is to reach Stamford at a quarter before six in the morning. – The Glasgow mail is to be taken entirely off this road, (it is to be made a branch or continuation of the Leeds mail;) but a new coach, to be called the York mail, is to travel at the same time as the Glasgow now does: it is to come from London by Biggleswade, and to go through Selby and Thorne to York, and forward to Newcastle and Edinburgh. This new coach is not to travel quite so fast as the other Edinburgh mail: it is to reach Stamford from London at half-past six in the morning, and is to pass upward at about the same time as the Glasgow mail now does, viz. 11 o’clock in the day. The coaches are to take separate lines northward from Bawtry instead of Ferrybridge.”
The Stamford Mercury, 25th March, 1825.
