Re your comment in another post about 10 megapixel images: They do
have their uses. For example, in this case you can see from the shape
of the dot over the 'i' in 'capacity' that it's in New Johnston Book
at a large size, contrary to the TfL design rules. (The dot is about
20 x 20 pixels, at which size it's possible to see that it has
concave sides to the diamond, a feature of New Johnston Book that is
not supposed to be readily visible. The rules say that NJ Book should
not be used at larger sizes than 12-point. New Johnston Light should
be used instead.)

But that's for signs. This is not a sign, it's part of a small photo, and
was not supposed to be looked at IRL. Use of New Johnston Book was IMO
correct.
