The service didn't stop between East Croydon and Brighton which for those
passengers makes it about as useful as an ash tray on a motorcycle.

Useless ****ing cretins.

You phrase it so eloquently. Some time last year I was at Brighton with
major disruption to services in progress anfd trying to get to work. A FCC
service was announced as departing for Bedford, first stop Blackfriars. It
was so pleasant not having to suffer those Useless ****ing Cretins who
normally get on at places such as Haywards Heath, Gatwick Airport, East
Croydon, Tulse Hill etc. etc.

AIUI FCC would not require GSM on 377s for the same reason that SN do.

The Victoria 377 problem is GSM, yes, sure, but it is for postioning
for SDO.

FCC/TL won't be using SDO ... they do not use it anywhere on their
network pre-KO0, there is no need for it at any of the ''underground''
stations. Hence they don't need GSM for this, so the delay etc will
not occur.

I don't know any reason why they will need underground SDO post KO0,
since the relevant stations are already 8car - we are not into +8car
yet and won't be for a long while, nor is FCC/TL putting in SDO. In
any case SPILL is already 12car (and thats the one people seem to be
commenting on) as is City.

There may be another reason for GSM, but not for postioning, and there
may well be GSM/SDO postioning somewhere, but not underground.

The problem therefore should not affect FCC/TL.

Oops - delete 'GSM' insert 'GPS' throughout above perhaps?

Maybe the programmers have also used GPS to control announcements, and
cannot run the announcement system without the doors bit as well, even
though it is redundant? Sounds a bit far fetched though doesn't it...

So the question then becomes, how easy is it to disable the GPS/SDO on
the 377/2 units? I assume that it won't be as easy as flipping a
switch, but will need an alteration to the units' software. Hopefully
the 377/5s will be delivered without the SDO enabled.

It's possible that the delay on the doors yesterday was for some other
reason, I suppose - I assumed GPS as I knew about the problems with
the 377 doors on SN. No idea what else it might be though.

(side note: some kind Google Groups user has marked my original post
as 1*, which seems a bit weird given that it's first-hand research on
an interesting and relevant railway topic. To which I can only say
'stick your ****ing head up your arse and leave it there til you die,
you petulant ****').

It could well have been another reason, but 90s does sound
suspiciously like the original delays at Victoria.

Well, I never use the Google Ratings, but I've gone back and given you
a 5, to keep your ranking up

I know maturity when I see it, well done for the expletives!

Doesn't it also work out which side of the train to open the doors on?

No, because the wheels are not a fixed diameter, but get gradually
smaller as they are turned on lathes to remove flats and
imperfections. A small difference in diameter will lead to a large
cummulative error, if no corrections are made. There are other systems
which measure distance travelled (for example radar), but I don't know
how they are affected by different track formations etc.

A more clever system could use the GPS data to derive how far the
train travels on one revolution on that day and use it later when the
GPS was not available.

OTOH, the Mk1 eyeball would also do the job, though I hear that there
was an incident of it failing to do so at Bletchley last week.
Fortunately, the Mk1 eyeball of the passengers prevailed, and (as one
would expect) nobody fell out.

AIUI some trains have been fitted with forward facing TV cameras as
well as the ones looking down the side of the train. If these were
coupled with some pattern recognition software and a set of images of
the stations served by the train then an electronic version of the Mk.
1 eyeball could be produced. It should be easy-peasy to work out if a
platform is beside the train or not. Not only that it could probably
work out which side of the train the platform is. If an infra-red
sensitive camera was used then it could also be used in fog and under
roofs in the dark.

If too much responsibility and action is removed from people operating
machinery or other things, then it can happen they are not as alert as
they could be when you really need it. If you see what I mean.
