What for?

I'll throw that one back at you and ask ''why not''. The Bakerloo goes
to Harrow (and used to go to Watford), the ELLX is projecting LU service
over NR routes, Croxley link (if ever) are examples.

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.


Its being designed for the tube system

Actually, no its not.

Don't be pedantic , you know exactly what I mean.


S-stock does NOT run in the tubes but on the sub-surface lines.

not national rail.
Different radio
systems, different ATP systems

So what ?

Err , so it wouldn't be able to run without extra kit? Which means
extra money? Which means more tax/fares from londoners to pay for
something which might one day maybe possibly when a cow jumps over a
blue moon get used once and then they discover the train layout isn't
suitable anyway for journeys of that length.

Stop looking at details and think about the bigger picture.

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


, possibly a slightly different loading
gauge,. not to mention
the 4th rail shoes dangling inbetween the rails that could foul some
mainline track systems.

So 4th rail surface trains are out of gauge at Wimbledon and Richmond
are they ? Met A stock knocks NR infrasture to pieces every time one
goes to Amersham ?

Other people have answered that.


S-stock is being built as common stock for all sub-surface lines. I'd be
pretty sure that spec would more or less put them within NR gauge.

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

And - as been pointed out already - District trains did used to run
further than then they do now to beyond Upminster.

So? This isn't the 1930s. It doesn't run there anymore and nor does it
have steam trains pulling the carraiges. Plus its highly unlikely it
ever will run there and even if it did then it would probably just
suffer the same fate as the east london line and become part of NR
using standard NR stock.

There was so much negative thinking in your response. If everything
proposed was dealt with your way nothing would ever move forward. It was

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.

I mean why not take your argument to its logical conclusion and make
every train everywhere in the country compatable with every line? Lets
fit 3rd rail shoes to pendilinos and class 91s for example, then we
could have through services then from edinburgh to Brighton via snow
hill!
