By the 1970s the carriages were a distinctive bright blue, but they were eventually discontinued and it is believed there are now just over 400 left in the world today.
Simon, who has received a Heritage Lottery Fund (HLF) grant to explore and exhibit the hidden and neglected heritage of invalid carriages, has been urging people who have memories of them to share images, memorabilia, video footage or stories which may help to inform his work.
As part of this project, Simon will present a talk, The Extreme World of 鈥楢C cars, Invalid Carriages and Cripples鈥�, at 6.00pm on Thursday 17 January at Preston Park Museum, Eaglescliffe, Stockton-on-Tees. Admission is free and open to all.
Simon, who is himself disabled, remembers his granddad having an invalid carriage and recalls how the vehicles were extremely primitive by today's standards and only suitable for one person. The vehicles were prone to break down and it was a common sight to find people stranded on their own.
There is a great beauty in these cars and we want to recognise their historical importance and present them in a way that will engage a whole new audience.
He has one of the world鈥檚 largest collections of invalid carriages, with 26 currently in his fleet. His interest in the preserving their memory and examining what happened to the rest of Britain鈥檚 invalid carriages led him to appear in a recent BBC Four television documentary on the history of the NHS.
Simon, who has exhibited his varied work all over the world, is working with Disability North, along with graduates in the University鈥檚 School of Computing, Media & the Arts鈥� Digital Studio, to create 3D animations and other digital assets as part of a major exhibition.
He said: 'There is a great beauty in these cars and we want to recognise their historical importance and present them in a way that will engage a whole new audience.'
