For those unfamiliar with the tangle of train lines in south , getting to grips with the official route map can be a bit of a headache. Max Roberts — an expert on metro mapping, whose radical designs we've discussed previously — has now reworked the network into a circle map.

Below, Max explains the background and rationale behind his new map. Judge for yourself whether it is an improvement on the official version.

Historically, the never had a monopoly of frequent electric services in London, and south of the , a journey by train would usually involve the Electric network, unfortunately.

Even today, with slam-door trains long-gone and operations privatised, these railways give the impression of a 19th century steam service that happens to be run by electric trains (hence my labels in the key). Service patterns are complex and uneven, varying by time of day. Stopping patterns can be arbitrary, and trains relatively infrequent (especially at evenings and Sundays). Such irregularities make this a formidable network to negotiate. The notoriously complicated ex-Central Division (London Bridge and Victoria to South London and Surrey) is certainly not for the fainthearted. In terms of user-friendliness, the railways of south London are probably among the worst in the world, up there with the RER and much worse than the New York Subway. I always cringe whenever an optimistic piece of marketing tries to brand these as ‘metro services', surely a breach of the Trade Descriptions Act.

But why should the Underground get all the circles? I've had my sights on south London for a while now, and after four attempts have finally got something that works reasonably well. Like all circles maps, this one has strengths and weaknesses. It struggles to tame the network in places, with many lines not quite radial and not quite orbital. The inherent complexity of the system is reflected in the final , a good map can't fix a bad network. In fact, this is only one of two designs where I had to refer to a track plan in order to be sure that I was getting it right (New was the other).

I was born in South London and endured the Southern Electric for two decades. I'm fully aware of everything I have had to do in order to get this one to work. All compromises and distortions were made with good reason. Any commentators wishing to complain about the geography or the shape of the design should refer back to current TfL maps of London's railways as a comparison. Only Beck, on his unpublished London Railway diagram from the 1930s managed a reasonable shape for the Southern Electric, although his attempt was full of errors.

Max has crafted circular maps for many cities, including , and Berlin. The south London circular rail map follows on from his reworking of the standard tube map.
