I decided to travel the subway and take some photos of the station signs.
The station walls are undergoing some renovations. Above is one version of the newer signage and tiles and below are an older version of the signs with the vertical tiles and showing the original version and the giant square subway tiles that was underneath, on the left.
(this just looks like it was taken in black and white, but it really is that colour)St Andrew station opened in 1963 (there is also a St George and St Patrick, but no St David station. none however were named after the saint or the cross or even England, Scotland or Ireland)
