Snowplows New York subway.
Reactive snowthrower, spray alcohol and other devices to deal with snow
I've always wondered how the New York subway is prepared for the cold and snow. Especially in view of its size and the number of open areas. It turned out that it is even ready. It is, of course, in such moments, works in emergency mode, but trains run in spite of the heavy snow and temperature fluctuations. This year the company MTA posted a lot of interesting pictures, which give the opportunity to look behind the scenes and look at their cleaning equipment and technologies work. Some were a surprise to me. I hasten to share.

1. relsoochistitel Jet - Jet Blower - devil-machine installed on it from a jet engine. Technique is very severe, so use it only in the depot and sidings. The principle is simple - using a powerful jet engine blows snow from all that comes her way. The temperature of the jet reaches 315c degrees, so most of the snow with ice in just evaporate. The main problem is a lot of noise, which is why jet relsoochistiteli rarely let out of custody.
2. wiper two propulsion diesel to move on ways and jet engines for blowing snow. On the cleaners, which are used in the New York subway, mounted engines General Electric / Westinghouse J57, which once stood on the B-52 bombers. In addition to the high rate they have another drawback - heavy loads they begin mercilessly smoke.
3. Cleaners assigned to longaylendskoy Railroad (LIRR) recently underwent an upgrade. They have established "new" jet engines Rolls Royce Viper, which are twice as economical old and almost no smoke. The "new" they are for the railroad - engines, as in the previous case, were removed from decommissioned aircraft. The power plant Rolls Royce Viper consumes about 378 liters of aviation fuel per hour at 70% load. Fuel tank capacity of 6800 liters. Ie machine can operate almost 18 hours without stopping.
4. Rotary snowplow - Snow Thrower - cleans and takes off towards the snow lying on the tracks, as well as clean contact rail with optional side brushes.
5. Can dumping snow at a distance of 60 meters. Productivity up to 3000 tons of snow per hour.
6. The main problem is that the snow to throw off nowhere in particular. Once the paths begin private territory.
Electricity supply for passenger trains is fed through a contact rail. It is a reliable thing, but almost nothing unprotected from snow. Therefore, clean it with a brush is a good thing, but, unfortunately, insufficient. Ice very poorly conductive, so If obledeneet contact rail, the train will stop eating and will rise.
7. To prevent such situations, there is a special car-ldoudalitel - De-Icer Car.
8. It is equipped with special shoes that scrape the contact rail system and spraying, which pours its deicing fluid. Tanks with liquid found inside the car.
9. De-Icer works in conjunction with a diesel locomotive and does not depend on electricity. The locomotive is equipped with snegootvalom and scrapers.
10. What would have been the level of mechanization, still can not do without the main worker - a man with a shovel.
11. Sometimes he comes to help people with a crowbar and a man with a broom.
12. Platform commuter trains are cleaned with the help of portable snow blowers. On the platforms above ground subway stations have to throw off the snow into piles in the center. If fold it down, it will fall on the heads of passers-by. After cleaning the surface generously with salt.
13 carriages of the train also undergo special training. Doors sprayed de-icing fluid, air brake line from the purified water, to prevent them from freezing, changing the current collectors shoes for winter, with holes so as not to adhere to the snow.
14. During severe frosts and snowfalls, the compositions put on the night in custody, and in subway tunnels. The benefit of the system allows rapid ways to do it without interfering with movement of night trains.
15. longaylenskoy rail a so-called "alcoholic train» - Alcohol train. The fact that nearly all suburban trains New York, as well as subway trains, are powered by the contact rail.
16. Accordingly, the contact rails and turnouts have to handle de-icing fluid. For this purpose, use so-called industrial alcohol. I understand that this is the same alcohol with additives. Hence the name of the train.
Another problem in the winter is freezing turnouts. This is a pretty complicated technical device uptime is essential that its elements no accumulation of ice and snow. Untranslatable arrows at the right position will halt movement. Solve the problem in different ways, depending on the design and transfer traffic at the site.
17. The arrows can be cleaned the old fashioned way - with a shovel, crowbar, a broom and such a mother.
18. Can be used for these purposes, a mobile blower. This is a very powerful machine with a pressurizing unit.
19. It operates not only in the winter. She blow away leaves, dust, dirt and even water. The machine can be moved on the rails at a speed of 80 km / h.
Just dig turnout is not enough. Move it still somehow unfreeze. For these purposes hexane, which is poured from a watering can along the track, and then set on fire. 15 minutes is usually enough for burning to was the result.
The arrow may have an autonomous heating system.
20. The most primitive system - using a kerosene heater. It is more advanced than scrap and broom, but no less antiquated method. In a special compartment located under the arrow put rags soaked in kerosene and set on fire. Such technology requires constant monitoring and gravy gorjuchki.
21. The next option is an arrow to the gas heating.
22. There is already required hoses gas pipes, which makes this method is not always feasible. The main problem of the gas heater in the fact that in a strong wind it can go out and have set fire again. During rush hour it can be a daunting task.
23. I do not know about the effectiveness and ease of use, but it is undoubtedly the most effective way. Discounted rail fascinating. I wonder what will happen if it will pass about spirtorazbryzgivayuschy train?
24. The most common and modern heating system turnouts - electric. The system includes a heater mounted on the outside of the rail and an automatic heating control system provided with sensors for temperature and rainfall. The system automatically activates the heating in the presence on the translation of snow or ice, and under conditions favorable for their formation. The photo clearly shows that all paths for the preheating zone are hidden under a thick layer of snow.
25. In case of strong snow drifts snow machines use different capacities. This is the newest Snow Fighter. When folded, it looks a bit unclear.
26. Here it is in action - shoveling snow to the side.
27. For the most complex cases has recently been bought by train nicknamed Darth Vader. It is never used, so there is no winter photos.
28. And my personal favorite around the huge fleet of cleaning equipment companies AIT. Although the idea of installing blade on a wheelbarrow for $ 40 000 and it seems to me somewhat crazy, but it looks cool.
29. Rather, to the snow was over.
Dyadya: I have everything! Thank you :)
