Hi,
Could you explain where you got your information from regarding the boundaries that you "clarified"? There doesn't seem to be have been any official process to change the boundaries. This article reflects the fact that the border crosses the station area: https://www.getreading.co.uk/news/property/plans-new-reading-station-building-16827876
Has something now changed officially?
By the way, I have a problem understanding what you mean here by "making the boundaries a bit clearer" - can you explain what you were intending?
Thanks!
