Where is Sir Isaac Newton ?

Perhaps the DfT are envisaging some sort of Newton's Cradle scheme for
getting trains out during power failures ? Put a train in at high speed
at the south end and a corresponding one pops out of the north ...

No - just alter the gradients so that it's low at Blackfriars and St
Pancras, but much higher in the middle.. :-)

Ah of course, their famous Brontosaurus In The Room scheme :-)

Doesn't that make some heroic assumptions that "they" know what the
job is? Lynn to Eastbourne requires more stock than Lynn to East
Croydon or Gatwick, surely?

I believe there is enough evidence in the public domain to strike both Kings
Lynn and Eastbourne from the route, namely the recent discovery of Kings
Lynn in the IEP programme, and the dissapearance of places like Eastbourne
and Littlehampton from the Thameslink final route maps in the more recent
South London RUS...

IEPs on the Cambridge fasts then?

It's looking likely. The South London RUS saw a major contraction in
the route map at the south end to inner-ish suburban, and there's also
been a recent disappearance of 2 ECML trains per hour from the final
MML/ECML split (was 14/10, now 16/8).

The old plan would have made poor use of King's Cross, leaving it half-
empty just as its redevelopment was complete. Although I don't know
what use the suburban shed will be post 2015.

Yes, I'd wondered about that too.

I suspect that they are thinking of a hybrid arrangement with
batteries or super capacitors, as have been proposed for light rail
schemes to avoid wiring up historic city squares.

There are a number of alternatives.

1) A development contract to the man who created the clockwork wind up
radio.

2 Or my favourite, RATOG (Rocket Assisted Take Off Gear) used on
carriers in the 1950s when the steam catapult was u/s.

3) Or the hydrogen peroxide powered steam turbine from the Spearfish
torpedo which gave over a megawatt

Over to Prof Breen.

the original artists' impressions of Manchester Metrolink, and I think
from ageing memory Leeds supertram, showed no wires, which is a far
cheaper way of avoiding complaints!

Terminating at KX, presumably. That's a shame, I was looking forward to
being able to get a through train.
