Trains at Wanstead station - Pauline Cavilla is back?!

Yesterday afternoon, I was revisiting Wanstead station on the Central Line's Hainault Loop, but for some reason, there were random moments when announcer Pauline Cavilla came online voicing "Ladies and gentlemen, please stand behind the yellow line as the train approaches. Use the full length of the platform. Let customers off the train first", essentially her signature announcement. But what was odd was that Elinor Hamilton was already voicing next train announcements like "The next train will arrive in 2mins. It will be a Central Line service calling at all stations to Ealing Broadway". You know, similar announcements as what you find at Victoria and at other stations. Now Pauline Cavilla was present at many stations when she recorded for the Tube back in 2011, and was mainly found on Bakerloo and Central line stations, along with select stations between Earl's Court and Edgware Road on the Circle and District lines. But when the phrase "ladies and gentlemen" was withdrawn in around 2017, stations began to withdraw Pauline Cavilla's recordings, with Notting Hill Gate and Bayswater being some of the last locations, withdrawing the recordings in 2024. I'm not sure if Pauline's random announcements at Wanstead were done out of error or not, but it sort of clashed with Elinor's more modern recordings. But it was ultimately pretty cool to hear Pauline's announcements again after a while
