Many times I needed the subway map to know where to board and / or change, so I had to search the metro map online, sometimes I did not have internet, with time I already downloaded the maps of the subway and metrobus
Now with this application I have the map of the metro, the metrobus, light rail and suburban train all offline (without internet) and I can put the maps on top of each other to see where the metro meets metrobus.
I already included the new line 7 of the metrobus.
It has a search engine for metro stations, metrobus, light rail and suburban train.
