Funnily enough, I was thinking of this theme on Wednesday... on a tram back from Crystal Peaks into Sheffield I passed the sign for "Elm Tree House" (on the way up from Gleadless to Manor Top).
At some time (1980ish?) South Yorkshire Transport changed "Manor Top" to the quainter sounding "Elm Tree". There's nowt quaint about Manor Top (as referred to in Reverend & The Makers "Heavyweight Champion Of The World") - it's the top of the hill near the large Manor Park council estate (and bordering other similar areas) - maybe someone thought that Elm Tree would sound more picturesque?
We've had others in Sheffield - e.g. when the SYT 21 to nearby "Woodthorpe" was replaced by the Eager Beaver 92 (in the days of double deckers being replaced by minibuses in funky colours with "cheap and cheerful" branding) the destination became the more interesting sounding "Fishponds" (despite the terminus being the same triangle of roads that the 21 had served).
The 31's northern terminus changed from Lower Walkley to Hillsborough.
The southern terminus of the long running 76 changed subtly from "Low Edges" to "Lowedges" shortly after Stagecoach started a competing 87 that referred to the suburb as one word rather than two (locals refer to it as one word, but there are other places in Sheffield where the Edge is a separate word, e.g. Nether Edge).
The SYT/Mainline/First 52 changed the name of its eastern terminus from "Woodhouse" to "Woodhouse Station" when the competing Stagecoach 52 was extended to Woodhouse Village.
To avoid doubt, the 31/52/76 continued to terminate in the same place, it's just the name used that changed.
Also, possibly not on any destination blinds, but we now refer to an area on the Sheffield/Rotherham border as "Waverley" and any mention of "Orgreave" has been banished to the 1980s (no buses terminate there, so it's off topic for this thread, but I guess nobody wants to be associated with the excesses of the Miners' Strike).
(yet, despite all this, a timetable for one of my parents local service continued to show a stop at "Safeway" ten years after the shop had become Morrisons)
More recently, in Bristol, buses to the Centre became City Centre
That's one I'd always wondered about but never got round to asking anyone - I didn't know if "Centre" was a particular place in the city centre (or just referred to the general area)?
Kind of the opposite of the Scottish thing of putting "The" at the start of something to make it sound grander (often applied to whisky brands but also referring to Waverley Station in Edinburgh as "The Waverley").
