If you look at old documentaries and photographs showing the process of building railway roads, then it is almost impossible not to be surprised. The endurance and strength of ordinary artel workers cannot go unnoticed. People, carrying a sleeper on their shoulders, carry it to their destination. And this is not a step or two to go, but a rather long distance.
To understand the full scale and assess the strength of the road workers, you should know how much one railroad tie weighs. To begin with, it is worth understanding what these sleepers are in general:
- edged - there is a cut on four sides;
Often the workers carried the last version of the sleepers on themselves. Each of the listed types has its own size and its own sectional shape.
If we assume that in pre-revolutionary times the length of unedged sleepers was 2.75 m, width - 0.28 m, height - 0.18 m, then we can conclude that the dimensions are quite serious. As for the average density of a certain wood, it is different for all tree species. Pine products have 500 kg / m3, and larch has 660 kg / m3.
Multiplying the indicators, we obtain the data for the weight of the sleeper. In the first case, the weight will be 69, 3 kilograms, and in the second, even more - 90.
Do many people now manage to carry 90 kg of weight on one shoulder? But in our time, everything is much simpler, since there is a variety of special equipment that makes it possible to significantly simplify and facilitate the work of workers. But before it was not.
By the way, not only representatives of the stronger sex, but also women already in the period of the USSR could cope with such power loads. Similar pictures can be found on the Internet. There is no doubt about their authenticity, since people were not familiar with Photoshop at that time.
Continuing the topic read, for which on many railway bridges, two strange rails are placed inside the track.
