Family tree of the sub-surface lines
Image: © Robert Lamb Taken: 30 Aug 2009
An interesting family tree done in the style of the tube map showing all the stock used in the past and present on the sub-surface (Circle, District, Metropolitan and Hammersmith and City lines), sub-surface meaning that the tunnels are just below ground level and are thus taller and square-shaped compared to the small and arched tunnels of the deep-level stock, hence why the stock is taller and more box-shaped than deep-level stock.
