Everyone has been saying for years that the current Overground map is terrible because the lines are not made visually distinct, unlike the Underground lines. TfL themselves agree, and there was an earlier proposal to improve this, but in 2015 mayor Boris Johnson allegedly nixed the idea.
Well, today some new names and colours have been announced, a mere 9 years later! Hurrah! But oh boy they’ve done a bad job of it.
The first complaint I saw was that they are not very distinctive for those who are colour blind. I’m not terribly convinced by this argument though. There are only a few colours that are sufficiently distinctive even for people with normal vision, and when you take into account the multiple different types of colour blindness there’s hardly anything left. As it is, for those with normal vision the “Weaver line” and “Windrush line” are hard to tell apart. Thankfully there are no stations shared between them.
I’m more concerned by the names. Only one of them is even slightly descriptive of where the line is or what places it connects. This is of course a sin perpetrated by many of the existing Underground lines, but just because you’ve got it wrong in the past doesn’t mean that you should continue to get it wrong in the future.
The “Liberty line” not only doesn’t tell you anything useful, it sounds like a dreadful Americanism.
The “Lioness line” is especially awful, partly because it makes a special celebratory case out of association football, partly because the “lionesses” moniker is just a bit of temporary marketing nonsense. And of course it doesn’t tell you anything useful.
The “Mildmay line” is named after a small hospital that hardly anyone has heard of. The name is actively misleading, as the two Overground stations closest to the Mildmay hospital are not on the Mildmay line!
The “Suffragette line” is, of course, named after a famous and worthy political campaigning movement. However, it doesn’t tell us anything useful about where the line is. Furthermore, the line already has a well-known name – it is the Goblin, so-called because it is the Gospel Oak to Barking LINe.
The “Weaver line” does at least have a vaguely descriptive name, in that it serves places historically associated with the weaving and cloth trade. But that association is not particularly well known so it still fails to be a useful name.
Finally, the only one that I like is the “Windrush line”. Named after the Empire Windrush ship which brought many of the first major wave of Caribbean immigrants to the UK, the line is quite nicely descriptive in that it serves an area that is well-known to have been settled by those immigrants.
