There are several issues with the current application. The portion of the system represented by the application is severely limited. It currently knows about the Central Line from Tottenham Court Road to Notting Hill Gate and the Bakerloo Line from Oxford Circus to Baker Street. That is only two lines and ten stations. Also, the generated travel instructions are rather tedious as they list all the stops that you should skip. Expand the Network: You are to add your name to the main program and add additional stations and lines to the network by completing the following items below. Follow the Capitalization, spacing and punctuation for the stations as they appear on the map.
