The connections at the other end are more important - the Goblin has
no equivalent to Canonbury tunnel, meaning southbound ECML trains
can't get onto it eaily. Plus anything electric. Plus various
occasional traffic like diverted sleepers heading for the ECML.

OTOH there is no access from the NLL to the MML, whereas from the Goblin
there is the connection via Junction Road Junction.
