'Not to scale'?
With only two stations shown how could it be otherwise?
I can send you a scaled map of the Waterloo and City line if you want to see a scaled map with only two stations. (No thank you. That's quite enough scaled maps. Ed)
UPDATE: This from Pedantic of Purley...
Well of course it is not to scale. It is a diagram. And
diagrams are, er, diagrammatic. It is not a map even though it is wrongly
referred to as a map. And the fact that no scale is specified means it is
unlikely to be to scale.
To be accurate First Great Western should have added something like “This
diagram is not an isometric representation of the portion of the network
illustrated” or “Diagram for illustrative purposes only” but a more sensible
thing would be to add nothing as it is perfectly obvious.
