We are well past the anticipated opening dates which were variously Jan
2011, Feb 2011 and possibly March 2011. Therefore dates like "late
Spring" or "early Summer" are now mentioned but you can debate what that
means.

Just so long as no-one mentions "late Summer"!

I can remember the Jubilee (Fleet) line being finished in a hurry for
something or other at Stratford, so important that the moving block
signalling was abandoned. Anyone remember what it was? What's the
likelihood something will delay the DLR and compromises will be made?

The opening of the millenium dome in North Greenwich, rather than
anything at Stratford.

There were multiple delays on the Jubilee extension, including
escalating costs, lack of promised finance, and worries about the New
Austrian Tunnelling Method used.

But the full moving block signalling had to be abandoned because it was
an untried system developed by Westinghouse, and couldn't be made to
work.

Thank you, I couldn't remember what it was.

Is that the same method, where the tunnel collapsed under Heathrow?

Isn't it moving block on the DLR? Have they got anywhere near getting
it working on the Jubilee yet?
Did I hear that the Jubilee was to be automatic like the Victoria and
Central lines are?

Yes, and Yes - the Jubilee has been using moving block since Christmas,
(it's known as the 'transmission based train control system' (TBTC)) ,
except for the section between Dollis Hill and Stanmore.

The conventional signalling is no longer used, which is why it is all
covered up.

Yes, and that's the reason for one of the Jubilee extension delays.

was an untried system developed by Westinghouse, and couldn't be made

Isn't it moving block on the DLR?

The Jubilee contract eventually went to Alcatel, who had provided a
workable system for the DLR, but the Jubilee solution was not full
moving block (partly because of difficulties integrating with the older
signalling on the rest of the Jubilee line).

Have they got anywhere near getting it working on the Jubilee yet?

I think that most of it is now working.

ITYM North Greenwich not Stratford.
I don't doubt you're right, but what was it that the Jubilee line was
finished in a hurry for?
