Sorry, which modern electric trains exactly - the 378s which run on
the NLL *and* the 3rd rail ELL all the way down to crystal palace? Do
they run faster or with better acceleration on the NLL then?

3rd rail is fine for frequent suburban and metro services but
increasingly hopeless for long distance passenger and freight
services. The huge benefit derived from power electronics is that dual
system trains are so much cheaper and more versatile so there is no
reason to keep third rail where 25KV would allow bore versatile
traffic, hence the electric spine re-powering project. It may have been
ahead of its time but it will come so freights too heavy for diesel
haulage can run in and out of Southampton.

I understand that all other things being equal 25Kv is the better
choice. However all the 378s are capable of 3rd rail and installing 3rd
rail on the goblin line would have meant little to no disruption of
services plus it would have cost a damn site less. Ok, so freight on the
line would still have to use diesels or 92s. So what - it always hauled
by diesels anyway from my experience probably because the wires don't
extend to whatever port or sidings its heading for anyway, not because
the goblin isn't wired up.

But the reson for electrifying Goblin is for freight thus need 25kV

"electrification of the Gospel Oak to Barking rail corridor, to improve
a key freight corridor and improving reliability for passengers. "

And 378s won't be used on GOBLIN either.

Is Spud related to Mr Ludd by any chance?
