University is one that really needs sorting. I'm aware of people who have turned up at Manchester Airport and expected - quite reasonably, in my opinion - that the ticket machine offering to sell them a ticket to "University" is selling them a ticket to the University of the city they have just arrived in, which has a station right next to it, not one in another city a hundred miles away!
It's an excellent example of something which wouldn't have been a problem at all when tickets were sold overwhelmingly at ticket offices (I can't imagine a ticket office clerk in Manchester selling a ticket to Birmingham for someone who just asked for "University" without making very sure that was what they meant!) - but certainly is a problem in the age of computer systems where passengers are expected to serve themselves. Some such systems do say "University (Birmingham)" but plenty don't.
In general removing station names that happen to contain a major place name other than the one they serve (e.g. Liverpool Street) is probably not a bad idea in principle, but not something I see an urgent need for. Likewise with eliminating duplicate station names.
The other suggestions - in particular, changing compass points - I'm not sure is very important. Perhaps the names are technically inaccurate but I can't see how they are causing a problem.
Yes, but that is no longer relevant to most travellers.
I am all for keeping traditions, but not this one.
Nor is the compass direction!
Most travellers trying to reach Wigan centre will follow signage (and if that signage isn't in place it should be - it's a relatively low cost and mitigates the frankly dreadful but all-too-common passenger experience of exiting a station and having no idea where you are), or look at a map, or plan their journey on their phone and follow the directions.
I would bet nobody is arriving at Wigan North Western, and saying "aha! I am at Wigan North Western, thus I know I must travel in a south-easterly direction to reach the town centre!" and then marching off in that direction with no further thought...
