So it's very difficult to remember all the ward names and their corresponding locations, especially if you're new to the hospital.
In Washington New Town in the North East, instead of names for the individual suburbs they gave them numbers. Only the numbers were shown on road signs. Nobody could ever find where they were supposed to be going and thankfully in the early 2000s they abandoned that stupid idea and gave the districts names.
Elizabeth line was widely maligned here, it's lazy argumentation to imply the reason anyone disagrees is a racist or wants to stop women from voting
The vast majority of the whingeing about these names comes from people who complain that the names are too "woke", whatever that means, and not from people who don't think the lines should have been named at all. Certainly on social media it seems to mostly come from the sorts of people who have hilariously observed that the Mayor's surname sounds a bit like a swear word.
The Elizabeth Line was slightly different in that it already had a perfectly good name- Crossrail- that had been in use for several years during construction. It even had its own logo. There was a genuine cost to changing the name compared to sticking with the name it had had for years.
But a bit like the Jubilee Line, which was always going to be called the Fleet Line right up until it was named after the Queen, the name didn't take long to stick.
If they'd called the Overground the (Winston) Churchill Line and the (Horatio) Nelson Line the ones complaining wouldn't care (although other groups of people would almost certainly have complained instead).
My general objection was that it was a waste of time and money, and the answer to a problem that didn't exist.
The Overground being an amorphous blob of orange spaghetti was a problem that needed sorting, though. Sorting it out was a manifesto promise from the Mayor. Manifesto promises only get made by politicians when politician making them knows for certain that it is something that people care about. If nobody else is bothered, the politician is not bothered. Certainly not bothered enough to stick it in their manifesto.
The actual names don't matter, the cost would have been the same.
*underground lines in London have names.
The Waterloo and City Line had a name long before it was an Underground line.
