Until fairly recently it was possible to download (pdfs) excellent maps of bus routes serving various stations, districts etc eg bus services from Marble Arch, bus services from Paddington station, Liverpool Street , Euston etc.. These were in a format similar to the currently available map of bus services in Central London obtainable from tfl. These were excellent maps, very clear and easy to use to navigate around the capital, showing local bus routes and interchange points with rail services. They were ideal in providing an overview of quite a large area. The present system presupposes a knowledge of which bus/route one needs to use. What has happened to these excellent maps??
