I have read in these newsgroups that the only two things holding up
the electrification of the GOBLIN and the implementation of 378s on
this route are the short platforms at South Tottenham station
(necessitated by the junctions at either end) and the inability to
find funding for the electrification. Are both of these problems still
without solutions, or are there solutions available awaiting the
necessary funding (which won't arrive until 2016 at the earliest
IMHO)?

Also, are the 172s any good? I've not sampled them yet so I'm
interested to know if the GOBLIN has had a mini-sparks effect thanks
to the newer trains.
