Its not unconfirmed. It says Edgemead quite clearly, it looks like Edgemead, the next stop is Leighton City on the 68, all the trains on the new line are going to edgemead or leighton city
I'm not sure, but there might be a small chance to see minor changes to Milcastle Racecourse due to Milcastle Scenery Upgrade, I don't mean the station but maybe the entrance and stairs.
