1
00:00:04,740 --> 00:00:06,740
And finally, a piece of technological heritage.

2
00:00:06,820 --> 00:00:09,700
Poland's last working Odra computer.

3
00:00:09,780 --> 00:00:11,460
We found it in Wrocław.

4
00:00:11,540 --> 00:00:15,460
For 30 years, it has managed Wrocław-Brochów railway station.

5
00:00:15,540 --> 00:00:18,980
How does it work? Kacper Cecota reports.

6
00:00:20,710 --> 00:00:24,470
Wrocław-Brochów is the largest freight yard in Lower Silesia.

7
00:00:24,550 --> 00:00:27,110
Information about every train and wagon

8
00:00:27,110 --> 00:00:31,430
entering the yard goes straight to the Odra computer.

9
00:00:31,510 --> 00:00:37,830
Model 1305 ensures no wagon goes missing and valuable cargo reaches its destination.

10
00:00:37,910 --> 00:00:39,590
It almost never makes a mistake.

11
00:00:39,670 --> 00:00:43,590
For its time, it was a very good, well-designed product.

12
00:00:43,670 --> 00:00:47,030
And, as you can see, it has served for all these years.

13
00:00:47,270 --> 00:00:51,030
So its quality was quite good, too.

14
00:00:51,510 --> 00:00:57,270
So good that today, Odra coordinates several newer computers at the railway station.

15
00:00:57,350 --> 00:00:59,990
It's the last working example in Poland.

16
00:01:00,070 --> 00:01:01,590
It occupies two rooms.

17
00:01:01,670 --> 00:01:07,030
It was built in 1986 by Elwro in Wrocław.

18
00:01:07,270 --> 00:01:12,870
I'm starting the consignees program for 1977.

19
00:01:12,950 --> 00:01:16,310
You'll get the information from the line printer.

20
00:01:17,790 --> 00:01:20,430
The first models appeared in the early 1960s.

21
00:01:20,750 --> 00:01:23,950
In its day, this was a major achievement in electronics.

22
00:01:24,030 --> 00:01:28,270
Odra and its applications were the subject of serious television debates.

23
00:01:28,350 --> 00:01:41,630
If raw materials were delivered, and products shipped, along routes calculated by computer, transport costs would fall by about 17 million zlotys.

24
00:01:41,710 --> 00:01:46,110
The late 1980s also marked the end of Elwro and Odra production.

25
00:01:46,190 --> 00:01:48,510
One computer after another became obsolete.

26
00:01:48,590 --> 00:01:54,430
Six years ago, Odra at Wrocław's Hutmen plant had a ceremonial send-off. Farewell, our Odra!

27
00:01:54,510 --> 00:01:59,470
Dear friend, for years to come, you will still be an example to us.

28
00:01:59,550 --> 00:02:02,990
A similar farewell awaits Polish State Railways staff.

29
00:02:03,070 --> 00:02:08,590
A new program is being developed for different equipment.

30
00:02:08,910 --> 00:02:09,950
And, well...

31
00:02:11,000 --> 00:02:13,320
I'll feel sad here.

32
00:02:13,640 --> 00:02:18,680
Odra's users say it will be switched off within weeks, perhaps even days.

33
00:02:18,760 --> 00:02:20,600
