Sydneys Super Tunnel -darkflix S02E03 Subtitles

At 00:00:01,770, Character said: In Australia, Sydney is on a mission.

2
At 00:00:04,910, Character said: There's still a huge amount of work that
we need to do.

3
At 00:00:07,590, Character said: To relieve chronic traffic congestion.

4
At 00:00:10,230, Character said: Sydney's traffic problems are incredibly
difficult to solve. By building a new

5
At 00:00:14,330, Character said: state -of -the -art metro system right
through the heart of the city.

6
At 00:00:20,630, Character said: But can it all be built underneath five
million busy people?

7
At 00:00:25,250, Character said: Huge logistical nightmare.

8
At 00:00:27,270, Character said: Without bringing them to a standstill. A
lot of things have to go right.

9
At 00:00:31,210, Character said: In sequence.

10
At 00:00:33,570, Character said: So an expert team of men and women from
around the world... Quite scary.

11
At 00:00:39,610, Character said: There's a lot that can go wrong.

12
At 00:00:41,370, Character said: ...are stepping up to this challenge
with some pleasure... Oh, wow, this is

13
At 00:00:47,470, Character said: amazing. ...and pain... I **.

14
At 00:00:50,470, Character said: ...along the way.

15
At 00:00:51,670, Character said: That's my station here. That's what we
built.

16
At 00:01:12,360, Character said: After years of tunneling, the five
megaboron machines on the $21 billion

17
At 00:01:18,620, Character said: line have completed their mission and
have left the building.

18
At 00:01:25,340, Character said: In their wake, more than 30 kilometres
of 7 -metre -wide concrete tunnels

19
At 00:01:31,020, Character said: remain.

20
At 00:01:32,580, Character said: The colossal station cabins are also
excavated, so it's time for this mega

21
At 00:01:38,600, Character said: -metro build to enter a new phase.

22
At 00:01:42,140, Character said: The project's really flipped around.
We've gone from that massive excavation

23
At 00:01:45,460, Character said: tunnelling stage to just as big a mega
problem, which is how do we deliver

24
At 00:01:50,060, Character said: everything into the tunnels and into the
stations and complete that build.

25
At 00:01:53,400, Character said: It's the build of the stations, but it's
also the track, the power, the systems

26
At 00:01:57,120, Character said: going in.

27
At 00:01:58,280, Character said: That's what's going to be the next
critical path to getting this railway

28
At 00:02:07,320, Character said: At Blues Point...

29
At 00:02:09,259, Character said: Deputy Project Director Nathan
Hofmeister can't wait to start getting

30
At 00:02:13,760, Character said: railway tracks down so train testing can
begin.

31
At 00:02:18,620, Character said: Now that we've removed all the earth,
we've g***t these lovely concrete line

32
At 00:02:22,340, Character said: tubes, we now need to pack these things
with rail infrastructure.

33
At 00:02:27,160, Character said: It's not as easy as it sounds.

34
At 00:02:29,520, Character said: The main way into the tunnels is through
the giant excavations where train

35
At 00:02:34,420, Character said: stations are being built at the same
time.

36
At 00:02:37,550, Character said: We need to feed all our tunnel
infrastructure through the station while

37
At 00:02:41,370, Character said: station's being built. There's a
constant juggling of priorities.

38
At 00:02:44,350, Character said: Who needs to go first? Who needs to go
second?

39
At 00:02:46,930, Character said: The rail crews will have to compete for
access at nearly every point because the

40
At 00:02:52,650, Character said: station builders have their own mega
challenges.

41
At 00:02:58,070, Character said: The first job we now need to do is get
the rail into the tunnels. We're going

42
At 00:03:01,970, Character said: thread the steel rails, 110 metres long
each.

43
At 00:03:05,290, Character said: through the tunnels all the way along so
we can start building the train.

44
At 00:03:09,670, Character said: As there is no train station being built
at Blues Point, Nathan and his team can

45
At 00:03:14,910, Character said: use the 35 -metre deep shaft as an
access point for equipment and

46
At 00:03:22,870, Character said: In the tunnels, the steel rails are
pulled to either side to allow

47
At 00:03:28,850, Character said: sections of concrete sleepers to be
brought in and laid one after another.

48
At 00:03:34,700, Character said: Once the sleepers are in, the rails are
lifted from either side of the tunnel

49
At 00:03:39,540, Character said: and carefully placed on top.

50
At 00:03:42,600, Character said: They are then manually attached to the
sleepers with metal clips and pan

51
At 00:03:47,220, Character said: pullers. And we have a dedicated
specially built concrete train that

52
At 00:03:51,800, Character said: delivers concrete to the front of the
track build. Nearly 100 ,000 tonnes of

53
At 00:03:56,340, Character said: concrete is needed to level the tunnels
and lock the 45 ,000 sleepers into the

54
At 00:04:02,700, Character said: ground.

55
At 00:04:04,760, Character said: Once the sleep is a place, the tunnels
are essentially blocked to heavy

56
At 00:04:09,200, Character said: machinery.

57
At 00:04:10,760, Character said: All it takes is one machine in the wrong
place.

58
At 00:04:14,300, Character said: If we get our sequencing and logistics
wrong, we end up with hundreds of

59
At 00:04:18,180, Character said: thousands of dollars worth of plants
potentially stuck in a tunnel behind a

60
At 00:04:21,260, Character said: concrete floor. It could be there for
months, it could be there for weeks.

61
At 00:04:24,200, Character said: a huge amount of downtime.

62
At 00:04:26,900, Character said: But the tracks are just the beginning.

63
At 00:04:29,440, Character said: As soon as the rails are locked down...

64
At 00:04:32,420, Character said: Services like power and data need to be
installed, and the big machines need to

65
At 00:04:36,940, Character said: go back into the tunnel.

66
At 00:04:39,560, Character said: We're just about to lower down a shaft,
a 10 -tonne high -rail truck, specialist

67
At 00:04:43,340, Character said: kit, down onto the newly formed track
down below the harbour so we can start

68
At 00:04:46,960, Character said: fitting off the bracketry on the side of
the tunnel.

69
At 00:04:49,840, Character said: We have millimetres either side as we're
lowering it down onto the track. The

70
At 00:04:53,960, Character said: skill of the operators is second to none
to make sure we get this pattern

71
At 00:04:57,040, Character said: safely. The high rail truck is a work
platform to carry and install cable

72
At 00:05:02,570, Character said: and walkways.

73
At 00:05:04,410, Character said: All the containment, all the services
are all hanging off the wall. Each one

74
At 00:05:08,270, Character said: those brackets needed dozens of holes
drilled.

75
At 00:05:10,910, Character said: We had an automated drilling rig that we
actually set up to drill holes all the

76
At 00:05:14,090, Character said: way along the full length of the tunnel.

77
At 00:05:17,450, Character said: The team must also install an elevated
metal walkway to enable maintenance and

78
At 00:05:23,570, Character said: emergency access.

79
At 00:05:25,050, Character said: That train will fly through those
tunnels in the future at 100 kilometres

80
At 00:05:28,330, Character said: hour, unmanned, driverless train.

81
At 00:05:30,530, Character said: Those brackets need to be millimetre
perfect. Those nuts and bolts need to be

82
At 00:05:34,390, Character said: tight. They've g***t to be triple checked.

83
At 00:05:36,010, Character said: Every little job, no matter how small it
seems, is critical, and everything's

84
At 00:05:40,330, Character said: being done to such a high level of
detail and quality.

85
At 00:05:43,370, Character said: But all this attention to detail takes
time, and the train testing team are

86
At 00:05:49,950, Character said: counting down the days until they can
launch.

87
At 00:05:58,890, Character said: About 35 kilometres northwest of the CBD
is the Sydney Metro Trains Facility.

88
At 00:06:05,810, Character said: It operates the first stage of the
driverless railway, and it's where the

89
At 00:06:11,030, Character said: are stabled and routinely maintained.

90
At 00:06:14,290, Character said: It's also home to a vital component of
the metro railway called the Operations

91
At 00:06:19,650, Character said: Control Centre, or the OCC.

92
At 00:06:24,170, Character said: I'm very excited to show you where we
are right now.

93
At 00:06:27,760, Character said: Pretty much like the brain in your body,
the OCC is the brain of our metro

94
At 00:06:33,320, Character said: railway. This brain is currently
operating the north -west line and will

95
At 00:06:39,640, Character said: the city line when it opens.

96
At 00:06:41,840, Character said: Our metro railway is unique.

97
At 00:06:44,220, Character said: The main difference between our metro
and other networks is that it is fully

98
At 00:06:49,520, Character said: automated. What that means is that our
trains are driverless.

99
At 00:06:53,800, Character said: Our stations are automatic and what that
actually also means is that you're able

100
At 00:06:59,020, Character said: to step into the train, head right in
front of the train, look outside the

101
At 00:07:03,440, Character said: window and see where you're going. The
system operates on a closed network,

102
At 00:07:08,120, Character said: protecting it from cyber threats as
hundreds of CCTV cameras monitor every

103
At 00:07:14,820, Character said: of the automated trains and stations.

104
At 00:07:17,780, Character said: OCC is...

105
At 00:07:20,080, Character said: connected via our network.

106
At 00:07:22,880, Character said: It's like the nervous system with all
the real -time information coming back

107
At 00:07:28,180, Character said: into the OCC to make real -time
decisions.

108
At 00:07:33,520, Character said: Melbourne heads to the maintenance shed
to get a closer look at this 21st

109
At 00:07:39,380, Character said: century rolling stock.

110
At 00:07:41,480, Character said: Technically, the train is...
