Why haven t diesel locomotives been eliminated from keeping up with the times?

Now there is still steam in Sandaoling, and the reason why it is not eliminated is because coal is cheaper than the oil burned by diesel locomotives. However, diesel locomotives require internal combustion engines because there are a large number of lines that are not electrified and the shunting operation is small. For example, the Qinghai-Tibet line has unelectrified areas, and the construction of catenary on the plateau is costly, so it is simply internal combustion.

There are also some local railways and corporate lines that are also unable to electrify.

History proves that the older things are, the more stable they are! Although China's mainline railways have been electrified, there are still many branch railways that are still ordinary railways, so the internal combustion engine is still useful. Secondly, the failure rate of the internal combustion engine is higher than that of the electric locomotive, and once the war breaks out, if the power grid is destroyed by the enemy, the electric locomotive will become an iron lump, and then it will have to rely on the diesel locomotive.

The operation of the electric locomotive is inseparable from the cooperation of the catenary, once the catenary fails, even if there is electricity, the electric locomotive can not run. Therefore, I assert that diesel locomotives will never be obsolete.

It will not be eliminated in a short period of time, although most of China's trunk lines and even branch lines have achieved electrification transformation, and the advantages of electric locomotives are also obvious, but some trunk lines still have not completed the electrification transformation of double lines, so they will not be eliminated for the time being.

China has not yet fully realized electrification, that is, the railway in some places must use diesel locomotives as traction power, and then the current electric locomotive has many advantages, but it has a fatal shortcoming - no electricity can not run.

The biggest advantage of diesel locomotives compared with electric locomotives is that they have strong environmental adaptability, and they can run as long as the railway is good. Therefore, the current diesel locomotive is also used as an emergency reserve, once the power system fails in the bad weather such as freezing rain and snow, and the electric locomotive cannot operate, it needs the diesel locomotive to play a role. In addition, once there is a war and the enemy destroys the power grid, the electric locomotive will be even more useless, and diesel locomotives will still be needed to transport materials.

Therefore, it is necessary to keep a certain number of diesel locomotives.

At present, China's railway electric locomotives have been popularized by more than half, and most of the railways that can take electric locomotives, diesel locomotives have been used very little, except for a small number of lines, which may be 50% of electricity and 50% of internal combustion. It can be said that looking at the current overall situation, electric locomotives are the mainstream.

Although electric locomotives are less noisy and less polluting than diesel locomotives. But the premise is that there must be electricity**, if there is no electricity**, then the electric locomotive will not be used. On the contrary, diesel locomotives are more adaptable to the environment than electric locomotives.

During the snow disaster in the south in 08, the railway catenary froze up, and it was pulled out by diesel locomotives.

Electric locomotives cannot operate without electricity, while diesel locomotives are different, as long as they are filled with fuel, they can run. Compared with oil and electricity, oil can be carried, while electricity cannot.

It is a national strategic resource that cannot be replaced, and the first enemy will destroy your power grid in wartime. This is the time for diesel locomotives to shine their might.

Diesel locomotives are still on the front line of passenger and freight transportation, but with the country's electrification transformation, it is a trend that diesel locomotives no longer exist, but it will not immediately retire all diesel locomotives.

Because diesel locomotives play a very large role when the catenary freezes, diesel locomotives will never be eliminated.

In the non-electrified railway tram is a ball of scrap metal, there is also the problem of starting in winter, not every line has a power grid, and the 25K and old 25G power supply systems can basically only use power generation cars.

The internal combustion engine does not need the external power grid and runs on its own fuel, although it is of little significance for civilian use (in the event of a heavy snow and other disasters, the signaling system generally does not work normally, and the diesel locomotive has a limited role), but it is very important for disaster relief and the military! In the event of a large ** and wartime, the power is generally difficult to stabilize**, and ordinary passenger passenger transport should also be temporarily middle finger, this is even if there is no signal light, the diesel locomotive can also rely on manual command, carrying materials or military equipment to drive, this is the ultimate mission of the internal combustion engine! So diesel locomotives will never be eliminated!

Diesel locomotives can also be constantly updated and improved, making them more economical, more reliable, and more widely used. It can be used in a wide range of countries and regions where power development is not available.

Diesel locomotives have a certain service life, and electrified railways also have a certain construction period. There will be a gradual move towards electrification. After all, the electric locomotive is guaranteed, and the maintenance is simple after all.

BYD has an electric mud truck, and the electric locomotive is equipped with a battery that is usually charged, and when the power is off, the battery is turned on, and it can be fully charged in 15 minutes after arriving at the station.

AC380V is the mode of the power generation vehicle, DC600V can be supplied by the machine, and once the catenary is powered off, the bus will be completely cupped, and the power generation vehicle will not have this problem.

This is a big trend, but don't forget that there are still many lines in our country that have not been electrified.

Mix is not recommended to be eliminated at all. In the event of a failure of electricity, it also relies on the internal combustion engine.

In the event of a natural disaster, it is still the diesel locomotive that runs ahead. For example, freezing rain causes damage to the catenary.

In the event of war, diesel locomotives are definitely a powerful logistical support.

Diesel locomotives will never be eliminated, and they are inseparable from internal combustion for downsizing and combat readiness.

Clean up the electricity, weather resistant on the internal combustion engine, horsepower on the steam engine!

If it weren't for the ice disaster of '08, diesel locomotives would have really been eliminated.

Electric locomotives can be widely used, but they can never replace diesel locomotives.

Once the power is cut off, the electric locomotive and the electric EMU are all lying in the nest.

The United States is still using diesel locomotives! Heavy duty without internal combustion is not good.

No.

First of all, the electric locomotive has a fatal weakness in the way of energy **: that is, the energy (electrical energy) of the electric locomotive comes from the catenary on the roof of the car.

In the non-electrified section, where there is no catenary, the electric locomotive is almost equivalent to an unpowered car. And this weakness is for diesel locomotives with their own energy generators (diesel engines).

Yes, no.

Therefore, in this regard, diesel locomotives can be used as a war readiness material in transportation, in the event of war or natural disasters.

resulting in the power system.

In the event of paralysis, rail transport can only rely on diesel locomotives to drive traction.

Secondly, basically most of the construction of China's railways is not completed at the same time as electrification, and there are many materials that are transported by the section of the railway that has been built during the construction, and in addition to transporting materials, there will also be railway engineering vehicles through, which can only rely on the traction of diesel locomotives to make it operate normally without electrification.

Third, non-electrified railways.

The cost of building electrified railways is relatively low, and for some relatively backward areas or some local environments, electrified lines are not allowed for the time being (such as the Qinghai-Tibet line).

Diesel locomotives undoubtedly became the only option.

Although the overall power of diesel locomotives is not as large as that of electric locomotives, with the progress of science and technology, the situation of diesel locomotives in power is gradually improving, and in many aspects (such as the speed of fortune), the performance of diesel locomotives is not inferior to electric locomotives or even more than electric locomotives.

It is impossible for diesel locomotives to be completely replaced by electric locomotives, but it is very likely that the imitation jujube will be replaced by new energy locomotives (such as battery locomotives, hydrogen energy locomotives, and even solar locomotives). Ready for dismantling.
