Not if you've thrown away the jigs, and/or there are compliance issues
with a new build of an old design.

And, of course, the 378s do not share a platform with the S stock. Neil is
wrong, as usual.

Same traction and control system which is the important part. The bodyshells
are all built to order anyway.

I notice you never point our when you're wrong which is pretty often.
Still think ordering the 710s was a great idea?

Really?

Using jigs.

Yes, of course.

MITRAC.

Jigs arn't rocket science and reassembling some for an older design would be a
lot less expensive than the mess we have now.

Why not go ask some goblin passengers and see if they agree with you.

The issue is not if it was right to order the 710s. It's whether
TfL should have allowed for a delay preventing their being
in use by December, 2019.

Well they've never been blessed with foresight and they've
painted themselves into a tight corner. If they can't find
some spare 378s then it looks like it'll be a bustitute
until the 710s turn up - whenever that will be. If the delays
are as stated purely down to software issues then I'd venture
these issues are pretty intractable since they should have had an
off the shelf solution ready to go, its not exactly bleeding edge
tech.

And which software, exactly, have you reviewed and characterised as 'not
exactly bleeding edge'?

Train software. Its not stealth radar or a spacecraft control system they're
trying to get working. It moves in 1 dimension on a track and moving block
signalling and IGBT train control systems are a solved problem and should be
off the shelf packages from their suppliers. If Bombadier have been dumb enough
to write everything from scratch then more fool them and someone should get
their P45.
