It's snowing, can the train still run?

The rainy and snowy weather every day will not affect the train operation. One of the reasons is the "grinding device".

The surrounding environment along the railway has a great influence on wheel-rail adhesion, including leaves, plants, oil, water, ice and snow. When these pollutants are attached to the rail, the adhesion between the wheel and the rail will drop sharply, which will lead to the sliding of the locomotive wheel and the wear between the wheel and the rail.

However, there is a "sandbox" on the railway locomotive, which is filled with sand to increase the wheel-rail adhesion. The sand in the sandbox is specially used for railway locomotives after specific screening and drying procedures. When necessary, sand can be sprinkled on the driving wheel through the throat, which can increase the wheel-rail adhesion and thus increase the traction.

However, when the snow is too heavy, the train operation will be affected, causing the train to be delayed to varying degrees. In severe cases, the train will stop to ensure personal safety.

Extended data:

The impact of heavy snow on traffic;

1. Aviation: The impact of snowfall on aviation is obvious. In snowy weather, the visibility of the airport is seriously reduced, which affects the sight of flight personnel. In addition, snow and ice will seriously endanger the safety of the aircraft in the take-off and landing phase, because snow and ice will reduce and slide the friction on the ground, and the aircraft will not be able to take off and land, thus causing flight delays. ?

2. Railway: If it snows heavily and the snow depth exceeds 20 cm, the snow will accumulate on the turnout rail and frog, which will affect the train passing through the turnout. ?

3. Traffic in the city: On snowy days, the roads are slippery, and the traffic in the urban area is slow, which is very easy to be congested. Riding a bicycle or motorcycle in snowy days is easy to slip, the car can't stop, and it is easy to get out of control, causing accidents such as sideslip and rear-end collision. ?

4. Expressway: In snowy weather, the transportation department will close the expressway as appropriate. This is because the speed of the expressway is faster, and cars are prone to slip when driving on snowy roads, and accidents are prone to occur when encountering avoidance and overtaking. ?
