00:00:01,770 --> 00:00:04,In Australia, Sydney is on a mission.

00:00:04,910 --> 00:00:07,There's still a huge amount of work that
we need to do.

00:00:07,590 --> 00:00:09,To relieve chronic traffic congestion.

00:00:10,230 --> 00:00:14,Sydney's traffic problems are incredibly
difficult to solve. By building a new

00:00:14,330 --> 00:00:18,state -of -the -art metro system right
through the heart of the city.

00:00:20,630 --> 00:00:25,But can it all be built underneath five
million busy people?

00:00:25,250 --> 00:00:26,Huge logistical nightmare.

00:00:27,270 --> 00:00:30,Without bringing them to a standstill. A
lot of things have to go right.

00:00:31,210 --> 00:00:32,In sequence.

00:00:33,570 --> 00:00:39,So an expert team of men and women from
around the world... Quite scary.

00:00:39,610 --> 00:00:41,There's a lot that can go wrong.

00:00:41,370 --> 00:00:47,...are stepping up to this challenge
with some pleasure... Oh, wow, this is

00:00:47,470 --> 00:00:49,amazing. ...and pain... I **.

00:00:50,470 --> 00:00:51,...along the way.

00:00:51,670 --> 00:00:53,That's my station here. That's what we
built.

00:01:12,360 --> 00:01:18,After years of tunneling, the five
megaboron machines on the $21 billion

00:01:18,620 --> 00:01:24,line have completed their mission and
have left the building.

00:01:25,340 --> 00:01:31,In their wake, more than 30 kilometres
of 7 -metre -wide concrete tunnels

00:01:31,020 --> 00:01:32,remain.

00:01:32,580 --> 00:01:38,The colossal station cabins are also
excavated, so it's time for this mega

00:01:38,600 --> 00:01:41,-metro build to enter a new phase.

00:01:42,140 --> 00:01:45,The project's really flipped around.
We've gone from that massive excavation

00:01:45,460 --> 00:01:50,tunnelling stage to just as big a mega
problem, which is how do we deliver

00:01:50,060 --> 00:01:52,everything into the tunnels and into the
stations and complete that build.

00:01:53,400 --> 00:01:57,It's the build of the stations, but it's
also the track, the power, the systems

00:01:57,120 --> 00:01:58,going in.

00:01:58,280 --> 00:02:01,That's what's going to be the next
critical path to getting this railway

00:02:07,320 --> 00:02:08,At Blues Point...

00:02:09,259 --> 00:02:13,Deputy Project Director Nathan
Hofmeister can't wait to start getting

00:02:13,760 --> 00:02:16,railway tracks down so train testing can
begin.

00:02:18,620 --> 00:02:22,Now that we've removed all the earth,
we've g***t these lovely concrete line

00:02:22,340 --> 00:02:25,tubes, we now need to pack these things
with rail infrastructure.

00:02:27,160 --> 00:02:28,It's not as easy as it sounds.

00:02:29,520 --> 00:02:34,The main way into the tunnels is through
the giant excavations where train

00:02:34,420 --> 00:02:36,stations are being built at the same
time.

00:02:37,550 --> 00:02:41,We need to feed all our tunnel
infrastructure through the station while

00:02:41,370 --> 00:02:44,station's being built. There's a
constant juggling of priorities.

00:02:44,350 --> 00:02:46,Who needs to go first? Who needs to go
second?

00:02:46,930 --> 00:02:52,The rail crews will have to compete for
access at nearly every point because the

00:02:52,650 --> 00:02:55,station builders have their own mega
challenges.

00:02:58,070 --> 00:03:01,The first job we now need to do is get
the rail into the tunnels. We're going

00:03:01,970 --> 00:03:04,thread the steel rails, 110 metres long
each.

00:03:05,290 --> 00:03:08,through the tunnels all the way along so
we can start building the train.

00:03:09,670 --> 00:03:14,As there is no train station being built
at Blues Point, Nathan and his team can

00:03:14,910 --> 00:03:19,use the 35 -metre deep shaft as an
access point for equipment and

00:03:22,870 --> 00:03:28,In the tunnels, the steel rails are
pulled to either side to allow

00:03:28,850 --> 00:03:33,sections of concrete sleepers to be
brought in and laid one after another.

00:03:34,700 --> 00:03:39,Once the sleepers are in, the rails are
lifted from either side of the tunnel

00:03:39,540 --> 00:03:41,and carefully placed on top.

00:03:42,600 --> 00:03:47,They are then manually attached to the
sleepers with metal clips and pan

00:03:47,220 --> 00:03:51,pullers. And we have a dedicated
specially built concrete train that

00:03:51,800 --> 00:03:56,delivers concrete to the front of the
track build. Nearly 100 ,000 tonnes of

00:03:56,340 --> 00:04:02,concrete is needed to level the tunnels
and lock the 45 ,000 sleepers into the

00:04:02,700 --> 00:04:03,ground.

00:04:04,760 --> 00:04:09,Once the sleep is a place, the tunnels
are essentially blocked to heavy

00:04:09,200 --> 00:04:10,machinery.

00:04:10,760 --> 00:04:13,All it takes is one machine in the wrong
place.

00:04:14,300 --> 00:04:18,If we get our sequencing and logistics
wrong, we end up with hundreds of

00:04:18,180 --> 00:04:21,thousands of dollars worth of plants
potentially stuck in a tunnel behind a

00:04:21,260 --> 00:04:24,concrete floor. It could be there for
months, it could be there for weeks.

00:04:24,200 --> 00:04:25,a huge amount of downtime.

00:04:26,900 --> 00:04:28,But the tracks are just the beginning.

00:04:29,440 --> 00:04:31,As soon as the rails are locked down...

00:04:32,420 --> 00:04:36,Services like power and data need to be
installed, and the big machines need to

00:04:36,940 --> 00:04:38,go back into the tunnel.

00:04:39,560 --> 00:04:43,We're just about to lower down a shaft,
a 10 -tonne high -rail truck, specialist

00:04:43,340 --> 00:04:46,kit, down onto the newly formed track
down below the harbour so we can start

00:04:46,960 --> 00:04:48,fitting off the bracketry on the side of
the tunnel.

00:04:49,840 --> 00:04:53,We have millimetres either side as we're
lowering it down onto the track. The

00:04:53,960 --> 00:04:57,skill of the operators is second to none
to make sure we get this pattern

00:04:57,040 --> 00:05:02,safely. The high rail truck is a work
platform to carry and install cable

00:05:02,570 --> 00:05:03,and walkways.

00:05:04,410 --> 00:05:08,All the containment, all the services
are all hanging off the wall. Each one

00:05:08,270 --> 00:05:10,those brackets needed dozens of holes
drilled.

00:05:10,910 --> 00:05:14,We had an automated drilling rig that we
actually set up to drill holes all the

00:05:14,090 --> 00:05:15,way along the full length of the tunnel.

00:05:17,450 --> 00:05:23,The team must also install an elevated
metal walkway to enable maintenance and

00:05:23,570 --> 00:05:24,emergency access.

00:05:25,050 --> 00:05:28,That train will fly through those
tunnels in the future at 100 kilometres

00:05:28,330 --> 00:05:30,hour, unmanned, driverless train.

00:05:30,530 --> 00:05:34,Those brackets need to be millimetre
perfect. Those nuts and bolts need to be

00:05:34,390 --> 00:05:35,tight. They've g***t to be triple checked.

00:05:36,010 --> 00:05:40,Every little job, no matter how small it
seems, is critical, and everything's

00:05:40,330 --> 00:05:42,being done to such a high level of
detail and quality.

00:05:43,370 --> 00:05:49,But all this attention to detail takes
time, and the train testing team are

00:05:49,950 --> 00:05:52,counting down the days until they can
launch.

00:05:58,890 --> 00:06:05,About 35 kilometres northwest of the CBD
is the Sydney Metro Trains Facility.

00:06:05,810 --> 00:06:11,It operates the first stage of the
driverless railway, and it's where the

00:06:11,030 --> 00:06:12,are stabled and routinely maintained.

00:06:14,290 --> 00:06:19,It's also home to a vital component of
the metro railway called the Operations

00:06:19,650 --> 00:06:22,Control Centre, or the OCC.

00:06:24,170 --> 00:06:27,I'm very excited to show you where we
are right now.

00:06:27,760 --> 00:06:33,Pretty much like the brain in your body,
the OCC is the brain of our metro

00:06:33,320 --> 00:06:39,railway. This brain is currently
operating the north -west line and will

00:06:39,640 --> 00:06:41,the city line when it opens.

00:06:41,840 --> 00:06:43,Our metro railway is unique.

00:06:44,220 --> 00:06:49,The main difference between our metro
and other networks is that it is fully

00:06:49,520 --> 00:06:53,automated. What that means is that our
trains are driverless.

00:06:53,800 --> 00:06:59,Our stations are automatic and what that
actually also means is that you're able

00:06:59,020 --> 00:07:03,to step into the train, head right in
front of the train, look outside the

00:07:03,440 --> 00:07:07,window and see where you're going. The
system operates on a closed network,

00:07:08,120 --> 00:07:14,protecting it from cyber threats as
hundreds of CCTV cameras monitor every

00:07:14,820 --> 00:07:16,of the automated trains and stations.

00:07:17,780 --> 00:07:19,OCC is...

00:07:20,080 --> 00:07:22,connected via our network.

00:07:22,880 --> 00:07:28,It's like the nervous system with all
the real -time information coming back

00:07:28,180 --> 00:07:31,into the OCC to make real -time
decisions.

00:07:33,520 --> 00:07:39,Melbourne heads to the maintenance shed
to get a closer look at this 21st

00:07:39,380 --> 00:07:40,century rolling stock.

00:07:41,480 --> 00:07:48,Technically, the train is...
