00:00:02.000 --> 00:00:03.903
Welcome to Read Listen Draw!

2
00:00:03.903 --> 00:00:07.708
This is Twenty-Five More Amazing Train
Facts, Volume Two.

3
00:00:07.708 --> 00:00:09.610
Let’s discover how railways work.

4
00:00:09.610 --> 00:00:10.371
All aboard!

5
00:00:10.371 --> 00:00:10.752
1.

6
00:00:10.752 --> 00:00:13.035
Train tracks have two steel rails.

7
00:00:13.035 --> 00:00:16.840
These strong, smooth strips guide the
wheels along the railway.

8
00:00:16.840 --> 00:00:17.220
2.

9
00:00:17.220 --> 00:00:20.265
Sleepers lie across the track beneath the
rails.

10
00:00:20.265 --> 00:00:24.070
They support the rails and help keep them
in position.

11
00:00:24.070 --> 00:00:24.450
3.

12
00:00:24.450 --> 00:00:27.875
The crushed stones beneath many tracks are
called ballast.

13
00:00:27.875 --> 00:00:31.680
They help support the sleepers and hold
the track steady.

14
00:00:33.300 --> 00:00:33.733
4.

15
00:00:33.733 --> 00:00:38.491
Inside a steam locomotive, a fire heats
water in a boiler.

16
00:00:38.491 --> 00:00:41.952
The water becomes steam that powers the
engine.

17
00:00:41.952 --> 00:00:42.384
5.

18
00:00:42.384 --> 00:00:44.980
Steam pushes pistons backwards and
forwards.

19
00:00:44.980 --> 00:00:50.171
Connecting rods carry that movement to the
driving wheels, making them turn.

20
00:00:50.171 --> 00:00:50.604
6.

21
00:00:50.604 --> 00:00:54.930
Many steam locomotives pull a special
vehicle called a tender.

22
00:00:54.930 --> 00:00:58.390
It carries water and fuel for the journey.

23
00:01:00.000 --> 00:01:00.439
7.

24
00:01:00.439 --> 00:01:03.947
A diesel-electric locomotive makes its own
electricity.

25
00:01:03.947 --> 00:01:10.087
Its diesel engine drives an alternator,
which supplies electric motors that turn
the wheels.

26
00:01:10.087 --> 00:01:10.525
8.

27
00:01:10.525 --> 00:01:16.226
Some electric trains collect power from a
third rail beside the running rails.

28
00:01:16.226 --> 00:01:19.735
Sliding contact shoes connect the train to
it.

29
00:01:19.735 --> 00:01:20.173
9.

30
00:01:20.173 --> 00:01:26.313
Some electric trains can return
electricity to the railway power supply
while slowing down.

31
00:01:26.313 --> 00:01:28.505
This is called regenerative braking.

32
00:01:30.075 --> 00:01:30.568
10.

33
00:01:30.568 --> 00:01:34.021
A boxcar is an enclosed freight wagon.

34
00:01:34.021 --> 00:01:38.461
Its roof and walls protect cargo from the
weather.

35
00:01:38.461 --> 00:01:38.954
11.

36
00:01:38.954 --> 00:01:43.394
Covered hopper wagons carry loose loads
such as grain.

37
00:01:43.394 --> 00:01:47.340
Sloping floors help the load flow out
underneath.

38
00:01:47.340 --> 00:01:47.834
12.

39
00:01:47.834 --> 00:01:50.300
Cylindrical tank wagons carry liquids.

40
00:01:50.300 --> 00:01:56.220
Some transport water, while others carry
ingredients such as thick, sweet molasses.

41
00:01:56.220 --> 00:01:56.713
13.

42
00:01:56.713 --> 00:01:59.673
Refrigerated boxcars control the
temperature inside.

43
00:01:59.673 --> 00:02:05.099
They help keep fruit and vegetables fresh
during their railway journey.

44
00:02:06.700 --> 00:02:07.141
14.

45
00:02:07.141 --> 00:02:11.115
Railway signals tell drivers whether they
may move ahead.

46
00:02:11.115 --> 00:02:14.646
They help trains travel safely along the
railway.

47
00:02:14.646 --> 00:02:15.088
15.

48
00:02:15.088 --> 00:02:17.736
Points are movable sections of track.

49
00:02:17.736 --> 00:02:23.034
They guide train wheels from one track
onto another at a junction.

50
00:02:23.034 --> 00:02:23.475
16.

51
00:02:23.475 --> 00:02:29.656
Track circuits use electricity to help
detect whether a section of railway is
occupied.

52
00:02:29.656 --> 00:02:33.629
This information helps the signalling
system control train movements.

53
00:02:35.175 --> 00:02:35.593
17.

54
00:02:35.593 --> 00:02:39.776
A machine called a tamper packs ballast
beneath the sleepers.

55
00:02:39.776 --> 00:02:43.958
It helps workers put the track in the
right position.

56
00:02:43.958 --> 00:02:44.376
18.

57
00:02:44.376 --> 00:02:47.722
Rail-grinding machines smooth the surface
of rails.

58
00:02:47.722 --> 00:02:52.323
Looking after the rail surface helps give
trains a smoother ride.

59
00:02:52.323 --> 00:02:52.741
19.

60
00:02:52.741 --> 00:02:55.669
Wet, crushed leaves can make rails
slippery.

61
00:02:55.669 --> 00:03:01.106
Special cleaning trains use powerful water
jets to wash the leaf coating away.

62
00:03:02.675 --> 00:03:03.096
20.

63
00:03:03.096 --> 00:03:06.890
Freight containers can travel by ship,
train and lorry.

64
00:03:06.890 --> 00:03:11.947
The whole container transfers between
them, without unpacking all the goods
inside.

65
00:03:11.947 --> 00:03:12.369
21.

66
00:03:12.369 --> 00:03:16.162
Special wagons called autoracks carry cars
and other vehicles.

67
00:03:16.162 --> 00:03:20.798
Their decks make room for vehicles at more
than one level.

68
00:03:20.798 --> 00:03:21.220
22.

69
00:03:21.220 --> 00:03:25.434
Some container wagons have a low space
called a well.

70
00:03:25.434 --> 00:03:29.649
On suitable routes, they can carry two
containers stacked together.

71
00:03:31.225 --> 00:03:31.642
23.

72
00:03:31.642 --> 00:03:37.069
Some freight trains have extra locomotives
in the middle or at the back.

73
00:03:37.069 --> 00:03:40.827
These can be controlled remotely from the
leading locomotive.

74
00:03:40.827 --> 00:03:41.244
24.

75
00:03:41.244 --> 00:03:44.166
A railway turntable is a rotating
platform.

76
00:03:44.166 --> 00:03:49.176
It can turn a locomotive so that it faces
a different direction.

77
00:03:49.176 --> 00:03:49.593
25.

78
00:03:49.593 --> 00:03:54.185
A funicular railway pulls its carriages
along rails using a cable.

79
00:03:54.185 --> 00:03:57.942
This makes it useful for climbing a steep
hillside.
