Tip: Click on lines to see the patterns of movement in each direction along each segment.
Line colours are the official colours for that line, as specified by TfL.

Only the higher of the flows in each direction are mapped, with arrows showing which way this is.

Station borders change colour - red indicate that more people are entering the station than interchanging in it or leaving it, black indicates more interchanges and green indicates more exits.

When comparing years, orange lines/stations indicate a fall in usage between the years. Blue stations indicate a rise in usage. The station areas and line thicknesses correspond to the size of the rise (or fall).
