If you're going to electrify anything, the Goblin is a marginally less
silly candidate than Bedford-Bletchley. Still going to be hard to
justify, at least until oil hits $100 a barrel...

Can't justify electrifying Goblin for the passenger service, even if TfL
increase it to 4tph. But if the new port at Thames Haven goes ahead, it
would make a lot of sense to allow freight off the Tilbury line to run
electric-hauled through to the WCML without having to go via Stratford,
crossing the GEML on the level and using the most congested section
(Stratford - Camden Road) of the NLL.
