These LU station axonometric maps are fascinating, But the combination of their age, and the fact that what they show doesn't seem geared particularly to what a passenger would need to know (and the fact that it's a partial set) makes them less useful than some of the NR ones are. I say some, since some of the latter are hopeless and simply silly in the way they're misleading. LU equivalents of the NR idea would be useful for some places - though where thyey're needed most they might well be almost impossible to render intelligently in two dimensions anyway.
On the other hand, for many LU stations, there's little need for such maps since the situation is very straightforward, usually signposted adequately, and with few extra facilities (like toilets and shops and so on - and ticket offices) that people need to know about.
