Euston Bank/Charing X Branch Announcements

[Busaholic]

Interestingly even though the platforms at Camden Town are split by northern branch (Edgware/High Barnet), southbound trains announce a branch name based on where they will go next after the junction, as heard for example at 21:23 and 22:20 in this "Northern line Full Journey From Edgware to Morden via Bank" Youtube video by X2K9.

This means that on approach to and at Camden Town the on-board announcements name the station as follows:
Platform 1 (Edgware branch northbound): "Camden Town (Edgware Branch)"
Platform 2 (Edgware branch southbound): "Camden Town (Bank Branch)" or "Camden Town (Charing Cross Branch)" depending on train
Platform 3 (High Barnet branch northbound): "Camden Town (High Barnet Branch)"
Platform 4 (High Barnet branch southbound): "Camden Town (Bank Branch)" or "Camden Town (Charing Cross Branch)" depending on train

That seems to me the most logical approach in those circumstances for those already on the train, providing just the right information without over-complicating it.
