But freights using GO-Barking cannot get on to the GE main line
(except with a double reversal). Is there any possibilty of a North
to East link where the lines cross?

Manor Park Cemetery is in the angle between the two lines. However, AIUI, a
significant proportion of the freight which comes up the GEML goes via the
NLL and WCML to the West Midlands or North West. This could all go via
Peterborough and Leicester when that route is upgraded. Freight from the
LTSR (which will increase considerably if/when the Shellhaven port
development goes ahead, and could in the future include fast freight from
Mainland Europe via Channel Tunnel and CTRL), if electrically hauled,
currently has to get across the whole of the GEML to access the NLL.
Upgrading and electrification of the Barking - Gospel Oak route for freight
could make a big difference to the GEML and the congested Stratford - Camden
Road part of the NLL.
