Could you expand on the cases which you think present difficulties?

A lot of the Southern routes are rather complicated to map ......

sure how a map could be simply coloured by London terminal destinations
without descending into trying to map the various combinations to give a

Wait a while and don't attempt to draw the diagram until after the service
is binned as per the South London RUS and ELL Phase 2?
