I appreciate them trialling new designs. Although I think the absolutely most confusing thing about the undergound (especially as a visitor or a newbie) is how incoming trains are labelled if there are multiple branches on a line. These will be labelled with the terminology terminus via midpoint of branch. Now this is fine to know, but sometimes there are station closures, redirections, early terminations which can cause new and confusing labels for a train you usually get. Visiting family seem to persistently get this wrong or confused. Northbound via Northern line, they need to get off at "Tufnell Park". 9/10 times this train is labelled as "High Barnet". So they look for that as I've explained, but this train might also be labelled "Mill Hill East" or 11 other labels it could possibly go to based on the terminating station. Going the other way they are equally confused. Going to "King's Cross" they need to catch "Morden via Bank", but to determine the name of the train you need you basically need to do a full scan of a fairly abstract diagram, find where you are, find where you need to go, then look beyond that for any possible terminus and the midpoint of the branch you need to take. I understand their initial confusion.
