Truly "fix" the GEML? The shopping list of expensive things:
Addtional tracks from Bethnal Green to Liverpool Street to take Lea Valley London Overground. Knock down the Broad Street development, build new platforms there, and obviously build on top of it again...
Which then releases the existing most northerly track pair and those platforms to be just West Anglia outers.
From Stratford to Ipswich, an additional pair of tracks. All the way. Allows separation of Metro (ie Crossrail), Suburban/local and Intercity.
