Mail Rail The Travel Show

US media has made fresh claims about purported links

between President Trump's transition team and the Russian government -

the subject of a current FBI investigation.

The latest allegations involve the President's son-in-law.

Bowser the headlines on BBC News. Now on BBC News, it is time for the

Travel Show. On The Travel Show this week:

Gigantic metal elephants. So this is how you make

an elephant roar. And exploring London's

secret tube network. The top speed of one of our mail

trains was about 35mph. We start this week

on France's River Loire. Along its banks, you'll find

some of the country's A chateau there were visited

by the likes of Joan of Arc, Leonardo Da Vinci

and Eleanor of Aquitaine. But we sent Keith Wallace

to the city of Nantes to find out how the region's industrial past

is being used to inspire Just over a decade ago,

this little island in the Loire was a scrap of wasteland close

to the centre of Nantes. A three-mile stretch of brownfield

site, home only to the odd artist who had gone there in search

of peace and quiet. But it didn't stay

peaceful for very long. In 2007 this, the Great

Elephant, began taking People came from all over to hitch

a ride in its belly. And, as it prepares to celebrate

its 10th birthday, they still come. So this is how you make an elephant

roar from inside its body. You can feel the whole thing

pull against your body All of these switches are twitching

every time the elephant's moving. The elephant rides form part

of the first huge push to turn The industry that had recently

departed had left a huge ugly scar just a stone's throw

from the historic centre. It's a crazy project

when you think about it, when they proposed to the city

to create an elephant that will carry people on his back and go

around on the Isle of Nantes. I mean, you have to ask money

for that, you can imagine that people were quite surprised

but the fact is that they managed to I mean, there are loads of cities

that have old industrial quarters that have been taken over by arty

types but this is different. This is about rivets and metal

and wood and workmanship In the mid-1970s, 60,000 people

made their living on this island but the ships started getting bigger

and bigger and the Loire was too narrow this far upstream

to accommodate them. 30 years ago, in 1987,

the last yard closed. These days, the old buildings are

occupied, not just by the elephant, All the animals began life

inside the head of Francois and he still gets a kick out

of the drama. And these are all dockyards,

aren't they, and they still feel But there's another influence,

the adventure writer Jules Verne was a son of Nantes and his book,

20,000 Leagues Under The Sea inspired the island's

gothic carousel. We are on the top level precisely

and under we have the deep sea and then the level of the sea

and at every level you have The idea is that you make a trip

and to dream basically. Since the carousel was built,

it's possible that Nantes skyline has become one of the most

distinctive in Europe and it's A 45-metre tall artificial tree

complete with mechanical herons Building work on that is scheduled

to begin soon with a finish Keith Wallace in the

French city of Nantes. And if you're thinking about heading

there any time soon, The Voyage of Nantes is an urban

trail that winds several miles through the city taking in dozen

of artistic and historical sites. The distinctive green line will take

you around all sorts of treasures, some of which are created especially

for the summer and many We have about 40 artists everywhere

in town with great installation, follow the green line,

it's kind of for children to discover the city

with their parents. At the end of June the Museum

of Fine Arts reopens It's been redeveloped

and expanded and will become one Treasures include works by Picasso,

Kandinsky and Max Ernst. If you want a glimpse

of some of the region's most important chateaux,

head a couple of hours up the river to places

like Chambord, Amboise, They're not only historically

important, they're also And finally, if you fancy joining

in the Great Elephant's birthday The venue is across the river

at the old quarry where the heron The latest in our series

looking at what the city This time we're off to meet

Baker Street's nocturnal florist. We can never shut down,

if something goes wrong. My name Kaleem and I work at flower

station as a night shift supervisor. It's used to be a petrol

station about 13 years ago Our customers at night are kind of,

you know, especially When they fight with each other

one thing can fix that One time somebody came 4am,

he said that a search on Google, only one shop open 24/7,

let's go there and fix it. The reason I am buying flowers

in the middle of the night, I have finished my shift as a taxi

driver, it's my wife's birthday tomorrow and hopefully this will be

a nice surprise for her. Yeah, I was looking

at the purple ones, as well. 24/7 really helps people

in Australia and America When they want to be afternoon,

everything going to be closed here. Celebrities, sometimes they come

and they choose their own flowers, they feel like they are in their own

heaven or in back gardens. In centre of London

you can never have that. We don't print out any letter

and send it to customer, I am the one at night

time who writes letters At night it is peaceful, everybody

is sleeping but we are working. I was thinking if I have a girl,

maybe girl I will give It's a flower name, it's one

of my favourite, Dahlia. I think flowers are the one

thing which can connect Stay with us because coming

up on The Travel Show: A neat way to book New York hotel

rooms by the minute. And I'm in London exploring

the secret tube network that's about to be opened to the public

for the first time. You're going to get a dodgy back

if you're walking down here all day. The Travel Show, your essential

guide, wherever you're headed. Time now for Trend and Travel,

your monthly mash-up of the best travel-related stories,

snaps and videos online. A few months ago

we met the Tiletsons. They launched a huge social media

campaign to find one lucky nanny who would join them

on a once-in-a-lifetime Well, almost 25,000 applications

later, they found their It was such an honour,

to have so much attention on us and so many people saying

yeah, take me. I called them and they were like

yeah, we wanted to see how your week has been and Derek goes,

can we switch over to Facetime. And I am like oh, obviously

I have the job, there was no way they're going to Facetime me

to tell me I won't do The group set off in July

and will be blogging This kickstarter

project has a solution. The unique travel set packs seven

pieces of women's clothing down into a single lightweight bag

with 30 different combinations. The project hit its funding target

earlier this month with a rollout Recharge is an app that lets

you book luxury hotel It's just launched in New York

offering customers a chance to use But be warned, if you're

still there when housekeeping And finally, one tweet

managed to save the life After reading about a Sumatran rhino

with a dangerous abscess, I immediately tweeted

at Saving the Survivors, and they put together

an international crew of vets that performed a highly

successful operation. The rhino has now recovered and is

living at a sanctuary in Malaysia. The Sumatran rhino is one of the

most endangered species on earth. There are fewer than 100 of them

left and if we're going to save them from extinction every single

last one counts. Thanks to everyone who sent

us their pictures this month Richard was in Hong Kong when he

snapped the daily light show. And no prizes for guessing where

this was taken, a famous landmark. Don't forget to check our

Twitter and Facebook feeds for loads of extra special

Travel Show content. Now let's look at the travel videos

clocking up the views online. With the European summer fast

approaching, we ride the waves with some

of the internet's surfing stars. They surf these waves a couple

of times a year but when we do, In my opinion, what makes

a great surfing film? You got to go for it

with what you got. You need to know your

way around the ocean. And if you don't know

what you're doing out there, you can find yourself

in a lot of trouble. And if you see anything you think

we should know about, Let's finish this week

deep underneath London. Final preparations are under way

to open to the public an underground train network most Londoners

will never even have heard of. Until 2003, it belonged

to the Royal Mail. Its tunnels snaked between

and alongside the regular tube, I've been told to come

to Liverpool Street station, the capital's gateway to the east

of England, to see it for myself. This really is the bowels

of Liverpool Street. I think there's a set of stairs

I am meant to go down. You can actually hear the old tube

trains kind of going down The station mirrors its counterpart

on the Central Line just above us. It just lacks that nice

tiling and polish. It's almost like stepping

back in time, isn't it? It's pretty much how

it was when we shut in 2003. Ray's worked down here ever

since it was decommissioned. He is one of three making sure

the tunnels are dry and safe. After a letter is received

at a sorting office if it needed to be transferred to the railways

or another sorting office it would be bagged up and sent down

to us and our trains ran it from East London at White Chapel

to Paddington in the west and it was a loop and we would send

trains round and they go continuously go around 22 hours

a day with a six-minute This was the 150 volt power supplies

for powering the trains If I hold that up there

you can work the handle. If I release that coil

it will drop out. Now that there are no trains

running through here it's Well, the whole railway

is six-and-a-half miles long but there's 22 miles of track laid

because it's double These are built on the hill,

so as the train approached it And as the train departed it

could naturally accelerate. You're going to get a dodgy back

if you're walking down here all day. You could develop

the mail rail walk. Still smaller than I

thought they would be. They're sort of half-size,

we use a two-foot gauge so it's quite narrow and they were unmanned,

so they were automatic. The top speed of one of our mail

trains was about 35mph. That's fairly perky,

though, it is pretty fast. Mail rail was very busy,

there were lots of people here, It was a noisy environment

with trains coming in and out. Lifts coming up and down and people

pushing mail containers around, And very soon paying

customers will be able to see In the next few weeks,

a brand new postal museum will hope here at Mount Pleasant in central

London. They're actually moving

all their archives to a purpose built centre just over the road

and the highlights This is traditionally

the heart of the network. This is where all the locomotives

would have been worked on and this will be the centre of the post

room museum experience. Sorry to point out the obvious,

but what is this thing? So, this is one of

the new locomotives. The centre piece will be a ride

through the tunnels below on the modern equivalent

of a mail train. OK, so this is where the driver

will sort of sit and co-ordinate. One train driver and

one guard per train. It's a huge project so there must

have been some challenges that you guys came across,

what were the biggest? We started off very much

from the point of view of it can be done and being honest we probable

thought there was a reason And as we got further

through the development I think we realised kind of how much

the public wanted the tunnels So do you think the British

public find an affinity The collections that we hold

represent 500 years And constantly innovating

and constantly changing and certainly in terms of post

offices they've been the glue that's While the ride is clearly

the main attraction, the routes of Royal Mail go

all the way back to Henry VIII. So the archivers have some

rich pickings to choose from as they assemble

the new exhibition. The post room museum

is scheduled to open in July. I'm afraid that's all the time

we have for this week. But join us next week when: I head

to Istanbul to take in the sights and sounds of a city that combines

two continents and thousands Along with some of best

Turkish baths in the world. With a good scrub you get a bit

of water on the head... But from me, Henry Golding,

and the rest of the Travel Show team here deep underground

in London, it's goodbye.
