Points

• There's an additional area at the top of map adding Luton, St Albans and Welwyn Garden City

• West Ealing, Hanwell and Acton Main Line no longer served by GWR

• Reading now included using a vertical trajectory with branch lines branching off to the south rather than the north.

There are five places where lines are drawn wrongly to ease the cartographers job (based on the notion that you can't have a station name separated from its station by another service not stopping there). There's London Northwestern avoiding Queen's Park, Greater Anglia avoiding Bethnal Green and running south of Mile End, Heathrow Express striking its own route south of Ealing Broadway and now:

• EMR taking a new route between Kentish Town and Mill Hill through Hampstead by the Northern line (EMR introduced as it stops at Luton Airport Parkway which is newly on the map).

• TfL Rail to Reading added with GWR branches 'towards' Windsor & Eton Central, Marlow, Henley-on-Thames and the west. Uses an ungeographic vertical trajectory

• Acton Main Line station (wrong side of Central Line) caption moved to other side and Heathrow Express moved further away due to GWR no longer calling there

• River boat connections added - but not all, eg Westferry, Canary Wharf, Putney Bridge, Waterloo

• Not new: Layer issues on High Speed all the way from St Pancras to Barking as it is in tunnel under the other surface lines; NLL should go over Thameslink at Hampstead; by South Hampstead

• Bridge (white keylines) at Hoxton but not at Poplar
