Handborough on the Cotswold Line had the spelling slightly changed in the mid '90s to Hanborough.
This is closer to the actual name of the village in which it is located - Long Hanborough.
When the eastern end of the Oxford Worcester and Wolverhampton Railway opened in 1853, places names in the area (and the rest of the country) were something of a moveable feast, including Hanborough/Handborough.
The OWW went with the spelling including the d, but the version without it then became the one used more generally, including in the world of officialdom, with the railways taking quite a while to catch up.
You get the same thing with nearby Wolvercote - which in the mid-19th century was often spelled without the e on the end, which is how Wolvercot Junction remained on the railway map from 1853 until 2018, when it became Wolvercote North Junction in the Oxford area resignalling scheme.
And in Bletchingdon/Bletchington, near Kidlington, the issue has never been fully resolved, so the road sign at the entrance to one end of the village uses the version with a d and the one at the other end uses the version with a t - locals tend to just call it Bletch.
There are plenty of other examples around the country. While it had been resolved by the time the Oswestry & Newtown Railway got there, Welshpool was originally known as Pool, then from the 15th centre or thereabouts, it was often referred to as Welsh Pool - to distinguish it from Poole in Dorset and Pool (-in-Wharfedale) in Yorkshire. The single word Welshpool seems to have become the preferred version a couple of hundred years ago.
