Abelio Greater Anglia calling at TFL rail stations

I can't explain the stopping pattern issue as to the purpose.

The only thing of potential relevance is that I read in this post is that the DfT have "permitted" the new Anglia franchisee (Abellio as finally confirmed today) to not have to call at a number of intermediate stops like Gidea Park, Seven Kings, Romford and Edmonton Green from the start of "TSR2" (a franchise milestone - presumably when faster, more frequent services start running to a new timetable). As Jukes said in the linked to post TSR2 is May 2019 which links in rather nicely with Crossrail running into the tunnel from the east and presumably also residual services into Liv St surface. The assumption must be that Crossrail trains will "rule the roost" from May 2019 on the local lines and faster trains don't need to stop.

In the Anglia ITT there are spreadsheets setting out the tph stopping requirements. Nothing required on the local stops on the GEML for TSR2 but there is a requirement in TSR1 (effectively what it's like now) to have an early train call at Gidea Park and Seven Kings.

The Southend trains (off peak) used to call Stratford, Ilford, Romford then all stations to Southend. However, they used the slow lines. Back then, the metro service was every 20 mins to Gidea Park only - trains only ran to Shenfield in the peaks.
