Except it isn’t, as this thread shows. Neither are acceptable, but in many cases the ‘St. Pancake’ example is worse because it is a fictional station and it is appearing on screens which are primarily used to find trains to a particular destination. Those with dyslexia or whose first language isn’t English do struggle with these fictional names.
Conversely, whilst Bond Street is a problem it is for different reasons. When travelling to the station all other information (other stations, on-train maps and signage and audiovisual announcements) still refer to Bond Street. The issue comes either after alighting for confirmation of the correct destination or when trying to find the station - particularly somewhere like Oxford Street where it’s entirely reasonable to have a ‘funnied’ roundel that could easily be some kind of shop or other tourist attraction.
Both are bad. Both need to stop. It’s unlikely that anything can be done under the various equality/disability legislations (particularly as the LU and XR parts are governed by different rules) but it does seem that there is finally enough of a furore that people are waking up, rather than the usual praise (as highlighted above).
Ultimately, you can’t support St. Pancakes whilst condemning Burberry Street - neither should be happening.
