This is a relatively old map, and it's also quite a strange map since
it's somewhere between the "London Connections" and the "Tube map",
showing the Croydon tramlink, Thameslink and Crossrail but not other
railways.
There's a few things that are definitely not going to happen.
Shoreditch is closed and will stay closed, the West London tram is very
unlikely, and the East London Line will be named Overground.
The Northern Line will hopefully be split by then, the Bakerloo
extended back to Watford Junction and the old Watford station would be
closed. Those are all much more likely projects than some of the ones
on this map.
