Without a doubt, this has to be one of my favourite transit maps ever. As far as I know, this isometric approach is unique and it is staggeringly effective. Everything is beautifully labelled, and lovely icons highlight important sites like the zoo, museums and sports stadiums. Unfortunately, this stunning map has since been replaced by a far more conventional diagram – a great loss in my opinion.

Have we been there? I’ve changed trains at the Hauptbahnhof, but have never ventured into the city itself.

What we like: The clever three-dimensional representation of the Hauptbahnhof, complete with corner tower, does a lot to complete the illusion of dimensionality. The isometric layout is a clever way of allowing all the type to be set horizontally without hitting route lines. Subtly different line weights for the S-Bahn and U-Bahn work really well.

What we don’t like: The isometric effect is so effective and convincing that the one and only horizontal line — the R31 across the top of the diagram — looks strangely out of place.

Our rating: Undeniably brilliant. 5 stars.
