Yes, Ely is the right answer.
On both occasions, 60007 is in platform 1, however mine was taken at the North End, while the previous entry was taken at the South end, from platform 2.
The OHLE equipment does vary in different parts of the station, there is even a cantilevered gantry just over the crossing, which is great for framing trains as they arrive into P2/3, as can be seen from this view taken a couple of minutes after the last.
Anyway- OPEN FLOOR!
