This map does not have the blue airbrush background from the 1939 edition. Mainline stations are indicated by a light blue triangle, and the Bakerloo line extension to Stanmore is open. The map continues to show as under construction the "New Works Plan" (Northern Heights project) to take over the ex-GNR line between Finsbury Park and Edgware and High Barnet, including the Alexandra Palace branch.
