Let’s look at car shields and cloud shields.
A barrier literally means ‘blocking a vehicle’. So it will be a railroad car here. A barrier refers to a facility or device that prevents a train or vehicle from leaving a location where it is supposed to stop.
The barrier is usually installed at the end of the line, that is, at the end of the line. It is common to see sidelines or safety sidelines rather than mainlines where the line has continuity.
At two-stage platforms such as Suseo Station and Yeosu Expo Station, they are also installed at the end of the main line.
Shall we take a look at domestic and foreign chamak first?
Overseas is unfortunate, but you have to be satisfied with 3-4 countries. As soon as overseas travel resumes, we will continue to add various barrier materials from various countries.
▲ A barrier at Kagoshima Chuo Station in Japan
A barrier sign is often installed on the barrier to indicate whether the barrier is installed or not, and indicates that you cannot proceed further.
The barrier marker can be installed on the barrier itself or behind it. In the case above, it was installed at the front.
It’s so big that I think it’s a bit excessive, so it’s covering the screen. It can be said that it is a surprise (?) outside the standard of a Japanese railway that starts with a sign and ends with a sign.
▲ It looks like a different form of the shield cover.
It is a simple form that is installed in the middle of a side line or unused line, not at the end, to indicate that further progress is not possible.
In other words, rather than the original role of a ‘shield’, it appears to be a substitute for a role as a cover.
▲ A barrier at Nagasaki Station in Japan
Nagasaki Station is the terminal station of the Nagasaki Main Line and has a two-level platform.
This is a barrier installed at the end of Nagasaki Station. By bending the end of the rail, it is a form that can play the role of a barrier and a wheel rolling block at the same time.
▲ Curtains at TRA Chiayi Station in Taiwan
The Alishan Forest Train, one of the world’s top three mountain trains, departs from Chiayi Station in Taiwan.
The Alishan Forest Train runs on a 762mm narrow gauge. This is an example of bending the rail with a small barrier at the starting line of the narrow gauge train.
▲ A barrier at Chiang Mai Station, Thailand
Have you ever seen such a pretty chamak?
It is a screen made by attaching two rails by welding and then firmly fixed to the rail. It is all about absorbing the kinetic energy of the car going round by the log, which is the contact part (painted part). It can be said that the purpose of installation is to stop and watch.
▲ It has the same shape as the barriers at Nagasaki Station in Japan.
The concrete wall behind the screen and the closed sleepers are attached to it for double defense.
▲ Blocks on the Oreum-gil monorail in Yeongju-dong, Busan (01)
It is a barrier to block relatively lightweight vehicles such as monorails and elevators. The circular elastic rubber will be able to receive some of the kinetic energy of the railroad car.
Apparently, monorails, especially lightweight monorails for 4-5 people, are small in size and most of them operate at low speeds, so the size of the barriers is also taken into account.
▲ Blockade of Yeongju-dong Oreum-gil monorail (02)
In the worst case, as above, the concrete bulkhead blocks it with the whole body so that it does not lead to secondary damage.
▲ A barrier for the 168-step monorail in Choryangibagu-gil, Busan.
It is a product of Korea Monorail, a monorail specialized company that produced the above Yeongju-dong Oreum-gil monorail, and has the same shape.
▲ The screen of Maya cable in Japan
A cable car that we commonly use is called a lift in Japan, and a cable car refers to a vehicle that operates using rails and cables.
This is the screen installed at the end of the cable car line.
Since most of the cars run at low speed, the barriers are also used as barriers by installing dampers on small steel structures and concrete walls.
▲ The screen of Rokko Cable in Japan
It is the same way as the Maya cable above.
▲ A barrier at Takamatsu Station in Japan
This is an example of using gravel tombs to absorb the vehicle’s kinetic energy first, and at the end to protect it in three layers with steel structure barriers and concrete bulkheads.
▲ The barriers at Seoul Station
Blockade using gravel graves and used sleepers
▲ Screens of the Incheon Maglev Railway
Nowadays, hydraulic dampers are widely used. It can effectively absorb the kinetic energy of an overspeeding vehicle.
It’s expensive, but it fits in tight spaces and looks good. Adjust the size of the damper according to the size of the driving vehicle and install it.
▲ Curtains of the Daegu Beommul vehicle base
Hydraulic barriers installed to fit the Daegu Line 3 monorail of 2 cars and 1 formation.
▲ A barrier at Namba Station in Japan
Namba Station of the two-stage platform. It is installed at the arrival line of the limited express train, absorbs the shock wave once with the connector and elastic rubber, and receives the entire force of the vehicle with the oil pressure device on both sides of the wall.
▲ A barrier at Ueno Station in Japan
It is a hydraulic barrier similar to Namba Station and is installed at the arrival line of limited express trains. Fixed to a rail instead of a wall, it is of such a size that it can absorb a considerable amount of force by itself.
In addition, elastic rubber, springs, hydraulics, and connectors are used to absorb collision energy.
▲ The shield of the wing shuttle at Kansai International Airport in Japan
This is a barrier for the shuttle train that runs from the boarding gate at Kansai International Airport to the immigration hall. It’s not easy to judge which way to shoot from the front.
It’s a pity that if I had taken a picture from the side, I would have been able to know more clearly. It was in the early days of railroad travel, so it was a time when filming skills were lacking.
If there is a method using different magnetic polarities between the vehicle and the curtain, I wonder if it will be the same as above.
▲ Blocks of a suspended monorail in Chiba Prefecture, Japan
If you go to Chiba Prefecture, Japan, you can see railroad cars that are rarely seen. It is a suspended monorail that runs directly on rails.
There can be no exceptions to the installation of screens for such suspended monorails. This is because the secondary damage is much greater if it derails beyond the stop position and falls into the car road below.
For this reason, you will install something that is more robust and has better performance than the barriers that are usually found on light rail.
Although it is not visible in the picture, a large spring is installed inside the curtain behind the curtain.
▲ Suspended monorail in Chiba Prefecture, Japan
Wheel base, wheel block, and receiving wheel rolling block are the same terms, only the terms have changed. Now it’s called a cloud cover. However, in practice, wheeled vehicles are still being used more often.
The cloud guard is used by fixing it under the wheels when it is necessary to attract vehicles or restrict movement for a certain period of time.
▲ It is a general form of water-retaining wheel cloud guard.
If you can clearly see the slope, you can install a cloud cover on the side where you can roll, but if you cannot determine the slope, install a cloud cover in both directions.
This is when both sides are installed on one wheel.
▲ Depending on the structure of the vehicle, if it is difficult to install the cloud guard on one wheel, it can be installed on both wheels.
▲ Cloud protection in Vietnam
It is a cloud cover made of iron. It’s in a slightly pushed state ^^ It seems that it was pushed because the cloud cover was made so that it could not completely enter the wheel and rail contact surface.
▲ Cloud protection at Thi Cau Station in Vietnam
It is a cloud cover that can prevent the vehicle from rolling. Some railway lines in Vietnam are 3-line complex gauge. A structure in the form of an accommodation wheel rolling block was obtained on three rails and fixed to the roadbed.
Although the size is large, it is difficult to call it a receiving wheel cloud because it is fixed in shape. Fixed wheel cloud cover? I guess I should call it like this.
▲ Cloud protection at Taipei Main Station, Taiwan
A cloud guard was also fixed to the end of the rail for the vehicles displayed in this way. It is also fixed, so it is not acceptable.
Since it is for display, it seems that it was installed only for show.
▲ It is an inverted cloud cover.
It is installed to prevent the vehicle from rolling out of a specific location.
It must be installed inside the vehicle contact limit sign and the heating device. Usually, in addition to the inverted cloud cover, the receiving wheel cloud cover is installed on the vehicle itself.
If there is no vehicle on the track, the open position is the normal position. You can often see inverted cloud blocking using waste tires.
▲ A barrier at Chiang Mai Station in Thailand?
Normally, if the barrier is to prevent vehicles traveling around the track, in the case above, it is preventing the hand car that has been placed inside from coming down.
Of course, it can also play a role in preventing entry into the hand.
It’s a bit ambiguous whether it’s a car curtain or a cloud cover. It’s a size that is not enough to block the entry of vehicles traveling around, so it would be better to view it with a cloud barrier.
▲ The rail bike’s cloud cover
It is not designed to be installed on wheels. By raising the body slightly and preventing the wheels from touching the rails, the rolling of the vehicle is fundamentally prevented.
It must be a vehicle with a weight that can be moved by human power as much as the body needs to be lifted.
▲ Bench at Chiang Mai Station Square
It’s a bench made with wheels. To prevent the wheel from rolling, a cute cloud guard is welded to the rail contact surface.
▲ The smallest cloud cover in the world?
It might even be the smallest cloud cover in the world. A handcar is placed on an unused track and the end of the rail is welded to serve as a cloud stopper.
▲ Anti-cloud measures on Tamsui Beach in Taiwan
If you go to Tamsui Beach in Taiwan, there are rails laid at the docking facility like this. Of course, it is not currently used and only traces remain.
It seems that they made a trolley-type transportation using waste sleepers and moved them using rails. And the vehicle was tied up with wires so that it could no longer go out to sea.
The shape is a little different, but I put it in because it plays a role as a cloud cover.
