1
00:00:03,550 --> 00:00:05,851
More than one container move in five

2
00:00:05,851 --> 00:00:09,813
carries nothing at all, and this
full box is about to join them

3
00:00:11,300 --> 00:00:14,136
Cargo flows are unequal between regions,

4
00:00:14,136 --> 00:00:19,169
so many boxes arriving full must be
sent back empty to where cargo waits

5
00:00:19,550 --> 00:00:22,188
At the freight station the doors open and

6
00:00:22,188 --> 00:00:25,726
the cargo leaves, and a working
box becomes a hollow one

7
00:00:27,550 --> 00:00:29,786
From here it is equipment rather than

8
00:00:29,786 --> 00:00:33,653
cargo, and it is moved to wherever
the schedule will need it next

9
00:00:35,550 --> 00:00:37,974
In the empty depot stacks climb higher

10
00:00:37,974 --> 00:00:42,440
than loaded ones can, because a box
with nothing inside weighs far less

11
00:00:43,550 --> 00:00:45,972
It usually leaves the stack only when a

12
00:00:45,972 --> 00:00:49,513
booking calls for it, and every
day it waits earns nothing

13
00:00:51,550 --> 00:00:54,153
Before it carries anything again a box

14
00:00:54,153 --> 00:00:58,058
must be clean, dry and sound,
so it is washed and repaired

15
00:00:59,550 --> 00:01:01,944
Once it passes inspection it rejoins the

16
00:01:01,944 --> 00:01:06,374
pool of available equipment, and
somewhere a booking is waiting to claim it

17
00:01:07,550 --> 00:01:10,211
Matching an empty box to a new booking is

18
00:01:10,211 --> 00:01:13,846
a quiet decision, and with
cargo inside it is whole again

19
00:01:15,550 --> 00:01:17,950
None of it makes headlines and it never

20
00:01:17,950 --> 00:01:21,643
ends, because a box emptied in
one place is needed in another

21
00:01:23,550 --> 00:01:26,174
The empty leg is never free, because much

22
00:01:26,174 --> 00:01:29,437
of its cost is carried in
the price of the full ones

23
00:01:31,550 --> 00:01:33,982
It is a dot again on the water, and the

24
00:01:33,982 --> 00:01:37,286
half nobody sees is what
keeps the other half possible
