TRADITION and a modern tourism image of Scotland will be mixed on the new Bank of Scotland £10 note, which will come into circulation in the autumn.

The bank has announced that the new polymer note will retain the portrait of Sir Walter Scott on the front alongside the image of The Mound, its historic head office.

On the reverse side the world-famous Glenfinnan Viaduct will remain, but with the addition of a steam locomotive hauling a heritage tourist train, echoing how the viaduct is featured in the Harry Potter movies.

Designed by banknote manufacturer De La Rue, the new note will incorporate the enhanced security features introduced on the polymer £5.

These include the anti-counterfeit “window effect”, which will be built into the windows of the image of The Mound, and the “rolling bar” metallic ink that changes colour as you move the note.

It will also include a new “Tactile Emboss” — created by a series of raised dots — that will aid visually impaired people.

All Bank of Scotland notes carry a portrait of Sir Walter Scott, who was a prominent figure in the campaign for Scottish banks to retain the right to print their own banknotes in 1826.

The Glenfinnan Viaduct carries the West Highland Railway line from Fort William to Mallaig.

It was designed by WS Wilson and built by Sir Robert McAlpine, and was completed in 1901. Reaching a quarter of mile long and standing more than 100 feet at its highest point, it was one of the largest concrete engineering projects ever undertaken.

The locomotive pictured on the new £10 note is a preserved Stanier “Black 5”, which was designed for the London, Midland and Scottish railway and often seen on the West Highland line.

Existing paper Bank of Scotland £10 notes will be gradually withdrawn following the issue of the new note, but any in circulation will retain their value and be accepted at shops, banks and cash payment machines.

Bank of Scotland director, Mike Moran, said: “Bank of Scotland has been issuing bank notes for 320 years, evolving our designs to pay homage to our heritage. The new note retains our much loved design of Sir Walter Scott with the famous Glenfinnan Viaduct pictured on the back and we’ve evolved the design by introducing the popular heritage tourist train crossing the bridge.

“With polymer notes being cleaner and more durable than paper notes I’m sure our new £10 note will prove popular across Scotland.”
