Terrific! Great idea. Good, simple graphics (which is as it should be) reflecting and, maybe, paying homage to London Underground's design heritage - since used as a benchmark by so many urban transport systems worldwide (and, ironically, now lost at its source). However, this is about more than that - potentially a far greater picture, encapsulating the UK's national rail network as well as specifics like London's DLR and Dublin's DART. On a personal basis my only negative is that it's of little practical use to me on a day-to-day basis at this time. Both the Underground and national networks need to be developed for the program to really become truly magnificent. Keep at it Mr Boros. The rewards will, most certainly, be there!
