The tragedy here is that one of the amazing features of the Cutty Sark
was that it was almost completely original. Whatever they now do with
it, that aspect has now gone.

It's just lucky that so much of it was elsewhere during the renovations.

Surprisingly enough I have seen the viking ships. They are well housed
in a really nice museum that is well worth a visit.

It is clear which parts have been replaced/restored. Sufficient to
give an idea of what the entire ship looked like, but not so much as
to swamp the originals.

The real travesty is the motorised 'lookalike' that pootles around
Oslo harbour - completely the wrong shape and doesn't even sail.

One of these days I'd like to sail a replica longship.

I didn't realise there was any left. I thought it had all been
turned into the Thatcher Memorial.

When my father and I visited Cutty Sark in the mid 1970s we walked
through the tunnel to the other side, we met one other person in the
tunnel. When we did the same thing a decade later the tunnel was
full of people.

That is the case with preserved trains. Even when they were working
things would be replaced, for example boilers. The more sensible
railways standardised boilers to make this easier.

A lot of preserved trains have bits for other trains, sometimes
quite large bits. However, much the same thing would have been done
in their working life.

Things become more interesting if they are to run on the big
railway. A number of bits of safety equipment are now necessary and
have to be fitted somewhere, does this mean they are no longer
"authentic"?

Why does this matter? If old knackered bits are replaced with newly made
bits it doesn't change the design or history of the ship and that's what
makes it what it is. Otherwise it's just a pile of old wood and metal.

The tunnel was built to get workers from the south of the Thames to
the docks on the north, that's when cycling in the tunnel was banned.
The ban remains in place today and the lift attendants threaten to
make you carry your bikes up the stairs if they catch you cycling.

The Woolwich Foot Tunnel is now as empty as the Greenwich Foot Tunnel
once was.

ISTR that there's a wooden temple in Kyoto which has burned to the ground at
least three times, and been rebuilt to the original spec. To the locals,
it's still the same building, which apparently heathen Westerners find
rather odd

A history that ends "and it is now preserved here" is different from one
that ends "and it was replaced with a replica after it was destroyed by
fire". We're now part-way between those two endings.

After all, the design and working history of the ship wouldn't have
been changed if it had been scrapped in 1954 instead of dry-docked.
Are you saying that wouldn't matter either?

Many Japanese temples and shrines, including the famous one at Ise, are
regularly rebuilt. Every twenty years at enormous expense in the
Ise-jingu case. Doesn't stop the tourist though.

If the original material is what matters, there's not much point in
keeping up with any of your old friends

The inverse square law is sadly neglected by alarmists. I know several
people who are scared of mobile phone cell masts, but aren't in the
slightest worried about spending hours with their own cell phone
clamped to their lug. And I know someone who was worried enough about
wifi radiation that he put the base station aerial very high up on the
wall to keep it at a distance from him while he sits with his laptop
on his knee

Incidentally, my wifi PDA lets me control its power by software, and
I've found that reducing it from 100mW to 4mW makes hardly any
noticeable difference. I suspect that where there's a lot of local
interfering transmissions (there's another half dozen local wifis
within range) it can be more than a square law where effective range
is concerned.

Indeed. If you make a single one minute call on a 1w mobile right
next to your head, that's the same energy dose as you'd get from a GSM
basestation 400m away.

These naysayers also fail to appreciate that they put cellular masts
where the traffic comes from i.e. their neighbours.

Preserved locomotives now have to be fitted with high intensity
headlights. At the moment this can be a portable battery operated
unit, though even this might be considered to spoil photographs.

They are now being fitted with train air brakes, which are not
authentic for most preserved steam locomotives and some preserved
diesels. Usually space is found on the tender of steam locomotives,
so as not to spoil the appearance (and sound) by fitting a
traditional air pump.

For some years they have been fitted with AWS and now TPWS. The
former is again not something some preserved steam locomotives had
fitted in their "working" lives, while the latter was obviously
never fitted.

Those locomotives working on particular lines have to be fitted with
RETB equipment. Those only making occasional forays just have
portable units, but I understand that those working on the lines
regularly have been fitted with RETB equipment permanently. Although
an electronic box of tricks with glowing displays is not authentic I
think this is very sensible.

When the ETCS part of ERTMS is introduced preserved locomotives will
at some point have to be fitted with it if they are to work over
lines where it is installed. That strikes me as very sensible.
Preserved locomotives are not toys by large machines capable of
causing death and injury, just like unpreserved ones. Some years ago
I saw a full size version of one of these
http://images.google.co.uk/imgres?i...s+pacific+locomotive&svnum=10&um=1&hl=en&sa=N
at Tamworth Low Level. She was having the water in her tender
replenished and, after some passenger trains had passed, set off
along the main line towards Stafford. Having something like that
crashing into the rear of another train, even at ISTR the speed
limit for such preserved locomotives of 75mph, would be just as
serious as if it was an unpreserved locomotive.

While all these things are I think necessary they can also be seen
as not being authentic if one takes a purist opinion.

Personally I think a modern version of the Cutty Sark should be built
and used to carry fairtrade tea from India & Sri Lanka. On arrival the
tea should be transported by rickshaw to the places in the UK where
people gather to drink tea. That would be some progress in the fights
against inequality & global warming.

Places such as the departure lounge at Heathrow?
