What is a high-speed freight train like?

CRTS track slab is used in most high-speed railways with a speed of 300 kilometers per hour that have been put into operation in China, and CRTS track slab ballastless railway is the high-speed railway. As the freight emu has not been mass-produced, the default freight train is a freight car with axle weight greater than 17t.

Because the axle load of locomotives and freight cars (generally 23-25t for locomotives and 0/7-30t for freight cars) is greater than the maximum axle load that ballastless track can bear stably (17t), with the increase of line operation time and passenger and freight volume, serious diseases appear. For example, between the bearing layer of the track plate and the crushed stone rolling layer, the problem of boiling and the sinking and skew of the track plate.

Precautions:

Common bulky goods include steel beams, steel pipes, steel plates and other steel products. These goods are mainly too long and need to be transported by vehicles such as extended, large trucks or semi-trailer trucks. There is also a kind of extra-wide and overweight goods, mostly steel and some commonly used construction machinery, such as engineering equipment components, bulldozers and excavators and other large mechanical equipment, which are usually transported by semi-trailer trucks or large flatbed trucks.

After loading these oversized goods, they must be loaded with steel cables and fixed firmly to prevent damage caused by sliding. For the tail of the goods beyond the body, a red light must be hung at night to facilitate the safe driving of the vehicle. For super-high and super-large heavy goods, in order to ensure the passage, it is necessary to investigate the transportation route in advance and make an emergency plan.

When transportation is needed, please ask the relevant departments to cooperate and clear the way when leading the way ahead, so as to clear the obstacles and pass smoothly. At the same time, due to the large volume of oversized goods, transportation is difficult. In the process of transportation, factors such as goods, means of transport and loading and unloading conditions should be comprehensively considered to ensure the safe delivery of goods.
