Thats a few extra miles on track that will be electrified to 4th rail
if it ever happens. Not all the way to the Thames estuary under 25Kv.

I did not say where to.

All I said was connection to Tilbury lines.

District Line trains to Fenchursh Street for example (capacity relief
District line taken up by reinstating NR trackage).

systems, different ATP systems

So what ?

Err , so it wouldn't be able to run without extra kit?

extra money? Which means more tax/fares from londoners to pay for
something which might one day maybe possibly

Approving something when a train is new and going through type approval
costs far far less than a retro-fit - the example of 365s v. 458s has
been cited many times. 365s were done all at new even though they were
in two single volt batches. That saved a lot when they moved the DC
batch from Kent to GN. 458s have limited redeployment choices because
they were never AC approved even though can technically handle it. This
is why 350 have now been DC approved, and so on.

What I was referring to was include AC in the s-stock testing spec, not
fit every train for AC and NR running.

Stop looking at details and think about the bigger picture.

Details tend to be important or things don't work.


But are not blocking points.



Yes , I'm sure "more or less" would be fine until it hits a bit of
trackside equipment.



This is EXACTLY what the Ludites said when Electrostars and Desiros came
to the Sr.


It doesn't run there anymore

Again so what.

That something once happened (eg Snow Hill) and was closed does not
prevent a restart (Thameslink).


And if everyone thought like you then we'd be paying through the nose
for trains with a compromise design and possibly redundant equipment
which would never get used.

No.

See above.

Testing and approving - not equipping until or if needed.



I mean why not take your argument to its logical conclusion and make
every train everywhere in the country compatable with every line?

Ideally they should be.
