This is a fun bespoke greetings card featuring the Stockton & Darlington Railway at Skerne Bridge in Darlington about 1827. The card arrives as a small square package and unfolds to its full delightful extent of Locomotion No.1 hauling waggons over Skerne Bridge with a horse drawn passenger coach to the rear. The building on the left is the Merchandising Station of 1826-7. The card is blank for your own message but because it is black you might need a coloured pen to write with.
The Skerne Bridge was going to be designed and built By George Stephenson using ironwork, but his other railway bridge further west had suffered problems in bad weather, the price of iron had rocketed and so confidence was low. The S&DR decided to bring in Ignatius Bonomi instead to design the bridge. He was the County Architect for Durham and designed the bridge in stone. The bridge needed some additional support within a short space of time, but remains in use today; it even featured on the British £5 note in the 1990s. It is the world’s oldest continuously operated railway bridge. You can read more about it here in an article by Brendan Boyle.
