A number of Welsh stations have had their spellings altered (corrected some would say). Memorably it is said that Dolgellau once featured three different versions on different nameboards shortly before closure.
But have any actually lost their English versions in favour of the Welsh form (by which I mean a different name, rather than a spelling change)?
Caergwrle opened as Bridge End in 1872, the became Caergwrle Castle in 1898, later becoming Caergwrle Castle and Wells, becoming Caergwrle in the 1970s.
However, the next station along the line: Hope opened in 1866 as Caergwrle! It then became Hope Village in 1899 and finally Hope in 1974.
Just to confuse the issue, there was then another station (now closed) further along the line called Hope Junction which opened in 1867, then the railway company (the Wrexham, Mold and Connah's Quay Railway) opened a new station in 1877 only 25 chains to the south which they called Hope Junction (and this time it really was at the junction between the WM&CQR) and the LNWR); the existing Hope Junction was then renamed Hope (WM&CQR) before being renamed Hope Exchange (even though there was already a Hope Exchange on the LNWR) but it was indeed an exchange for passengers between the two lines. In 1953 the original Hope Junction was renamed Hope High Level.
Meanwhile the LNWR station opened as Hope Passenger Exchange in 1867 and then became Hope Exchange, and finally Hope Low Level in 1953. It closed in 1958.
The Hope Junction station that opened in 1877 became Penyffordd for Hope later in 1877, then Penyffordd for Leeswood, and finally becoming the existing Penyffordd in 1974.
However the LNWR railway to Mold predated all of these and had a station in Penyffordd called Hope (of course!), which opened in 1849, it became Hope and Penyffordd in 1912, then closed in 1962.
