A century-old locomotive Erqi factory is about to stop production. Review the development history of diesel locomotives in Beijing

The farewell of the car is also the farewell of people.

Shuai Xicheng, born in 1971, is a dispatcher in the locomotive workshop. He is affectionately called "Shuai Diao" by the workers, and the last two locomotives were assembled under his command.

From accessories to complete locomotives, it is like assembling two giant toys weighing nearly 100 tons. "Shuai Diao" is like a big housekeeper, directing dozens of workers from fitters, electricians, welders and other types of work to break up parts together.

Shuai Xicheng (first from the right) arranges work for the workshop monitor.

Shuai Diao, who has the skill of staying in beauty, has been working in Erqi Factory for 30 years, but if you count his father Shuai Shijun, the connection between Shuai Diao and Erqi Factory has actually started since birth. The Erqi Factory, which was founded in 1897, has gone through more than 120 years’ history, leaving many workers of the second generation or even the third generation. Together with the Erqi Factory, these families witnessed the "Erqi Revolutionary Movement" and the birth of new China diesel locomotives.

Now, "Erqi Factory" bid farewell to its old job, and the workers will also bid farewell to the workshop. For the "second generation" and "third generation", it is like saying goodbye to relatives who have been together since birth. Soon after leaving his post, Shuai Diao squinted and smiled as usual: "Even if the workshop will no longer produce in the future, I still want to stay and work here. If a museum is built in the factory, I can at least be a commentator."

Unlike the "post-70s" and "the second generation of factories", young people are more willing to stick to their job skills.

Wang Zhiquan, the squad leader of the big class, born in 1989, is a proud pupil of ShuaiDiao. Besides the locomotive assembly technology, he also learned a smile from ShuaiDiao.

In 2008, Wang Zhiquan came to Beijing "Erqi Factory" from Datong, Shanxi Province. After ten years in the locomotive workshop, he took over the "handsome" class with excellent skills and became the squad leader responsible for the assembly of large parts.

Wang Zhiquan installed diesel engines for locomotives.

When hearing the news that "Erqi Factory" planned to move to Fangshan Doudian, he simply bought a house in Doudian and settled down, ready for a long time. Later, "Erqi" moved into a Doudian factory jointly built by "Changke" and "Erqi". CRRC provided the employees of "Erqi Factory" with the opportunity to transfer to the Doudian factory. Wang Zhiquan hoped to enter the new factory and continue to engage in assembly work: "With ten years of experience, there will be no problem in technology there."

Technology is the anchor of young people who are not afraid of the storm, and their down-to-earth attitude makes them shine a little in the last days of "Erqi Factory".

He Taotao, a fitter in the bogie workshop, was born in 1997, and has become the backbone of the workshop for two and a half years.

Before the Spring Festival, He Taotao, who was on vacation in his hometown in Shanxi, received a call from Wang Jianyong, director of the workshop, hoping that he could go back to the factory and build the wheels and bogies of the last two locomotives of Erqi Factory together with his colleagues. He immediately returned to the workshop without saying anything.

He Taotao took out the wheel of the last locomotive from the heating furnace.

"It’s amazing to shut down the factory after just two years!" In the joke, there is no complaining tone. For He Taotao, who was born after 1990, the loss of the factory is nothing more than changing a job. Whether in Beijing or back home, the salary of dry technology will not be too bad. "Coming out is to earn money. I learned locksmith. I can build trains and repair cars, but the parts are different. I am not afraid if I have skills."

A single young man has no worries about feeding his whole family, but the "parents" of "Erqi Factory" have much more complicated problems to consider.

Wang Jianyong, director of the bogie workshop, is also a "post-70s" and "second generation of the factory". As the director of the workshop, the first thing he thinks of when facing the notice of production suspension is the workshop staff. "The workshop director is like the parents of the workshop workers. What will the children do in the future if the factory stops production? I am at ease when they all have landed. "

In order to make more employees have better career development, he not only often talks with employees, arranges skills training for employees, but also actively contacts the equivalent industry units of Beijing Metro Operation Company, striving for more employees to make the best use of their talents and realize their career ideals.

Wang Jianyong (right) talks about future career development with Guo Ran and Zhang Ting, two young workers in the workshop.

Qiao Hongbo, born after 1960s, is the deputy general manager of CRRC Beijing Erqi Locomotive Co., Ltd., and also a "second child and seven people" who went from workshop to management position, and participated in the steering wheel during the transformation of the "Erqi Factory".

"The’ Erqi Factory’ is not gone, but transformed into a scientific, technological and cultural innovation city with cultural creation as the main body." Qiao Hongbo’s recent work has been around the new development after the transformation of "Erqi Factory". In the future, "Erqi Factory" should not only retain the red historical and industrial cultural relics, but also build a scientific and technological innovation park covering new media creation, artificial intelligence, rail transit equipment research and development and cultural tourism.

In the middle of this year, the first phase of the transformation of "Erqi Factory" will be officially completed and unveiled, and many leading scientific and cultural enterprises and stars have also expressed their intention to settle in.

At the beginning of the 20th century, the Xiaoyanglou, where foreign engineers lived, turned into an entrepreneur club in Wenchuang Park.

The locomotive workshop, which was built in the early 20th century, will remain intact as an industrial relic.

"We have made a request to our partners and enterprises, that is, we hope they can receive more employees from Erqi Factory, and enterprises are willing to cooperate. The placement of employees is a difficult point in the transformation, but we will do our best to help employees and’ Erqi Factory’ successfully transform together within the scope permitted by the policy. "

"Although the news of the suspension of production makes people feel lost, the’ Erqi Spirit’ is still there, and we can still see the bright future of the’ Erqi Factory’ in the new era!" Qiao Hongbo said.

Frameless door + electric rear wing, Mazda EZ-6 real car has now arrived at the store, and it is expected to start at 150,000 yuan

If in the era of fuel vehicles, it represents a persistent craftsman spirit, then in the current era of new energy, can Mazda still represent innovation and technology? Presumably many people’s answer to this question is vague, after all, Mazda’s pace in the field of electrification has just begun, and the cooperation can only be a test of the water work, whether it can win the favor of users, we need to observe for a while. Recently, some netizens have photographed that the real car of Mazda EZ-6 has arrived at the store. Interested netizens may wish to go to the store to experience it.


As a brand-new model, the Mazda EZ-6 is designed and built on the Changan EPA platform. It offers two options: an extended range version and a pure electric version. It is slightly larger in size, with a length, width and height of 4921/1890/1485 mm respectively, and a wheelbase of 2895 mm. The official position of the Mazda EZ-6 is a medium-sized sedan. From the actual photos, there are many shadows on the Mazda EZ-6, such as the beautiful design language. However, considering the positioning of new energy models, many LED embellishments that emphasize technological elements are still added. With a luminous logo, sharp headlights, and a three-dimensional front surround, the front face of this car looks very technological and sporty.

The most eye-catching feature on the side of the body is the use of the current popular hidden door handles, frameless doors and suspended roof, plus petal-shaped semi-hermetic wheels, which make the whole vehicle more dynamic. In terms of the tail, there are also two very recognizable designs, the first is the through tail lights and the semi-circular "gun downlights", which are very recognizable after lighting up at night. The second important feature is the electric rear wing, which is also equipped with a large-sized diversion diffuser at the bottom, so that the whole vehicle exudes a strong fighting atmosphere.

In terms of interior design, the Mazda EZ-6 adopts a minimalist style, such as a floating center control screen and a full LCD instrument panel that fits the current trend very well, while the flat-bottomed one adopts a touch design and integrates electronic arms. In addition, it is also equipped with AR-HUD and Qualcomm Snapdragon 8155 chips. Not only that, in the interior decoration of the vehicle, the EZ-6 model provides users with two unique design options: "Heron Feather White" and "Brown".

In terms of batteries, the new car will provide two capacity battery packs of 18.99kWh and 28.4kWh. The maximum pure electric cruising range under CLTC conditions is 105km and 160km respectively, and the comprehensive cruising range under full oil and full power is over 1100km.

BYD sold 219,800 batteries in China, but the DM version of non-bladed batteries.

Author: Hao Jun
Editor’s opinion:Byd Han went on the market, and what attracted much attention and enthusiasm was the blade battery. But when you buy it, you should see clearly … Not all the series are equipped with blade batteries, especially Han DM. Not only is it not a blade battery, but even the battery material is not Ferrous lithium phosphate, but ternary lithium. If you really choose to buy Han series because of the original acupuncture experiment, remember that the long-life version and the four-wheel drive version are the safer blade batteries. Look carefully when you buy, but this time the price is different and the material is different. Don’t be greedy and buy the wrong car.

On the evening of July 12, 2020, BYD Han officially went public, and launched four models, including three pure electric vehicles (Han EV) and one plug-in hybrid vehicle (Han DM). After comprehensive subsidies, the price range was 219.8-279.5 thousand yuan. The new car adopts Dragon Face family design language. The NEDC cruising range of the two long-life models is 605km, and the NEDC cruising range of the four-wheel drive high-performance model is 550km;. Han DM has a cruising range of 81km in pure electric mode. It is reported that in the future, BYD will build more than 100 business circle experience spaces in China, and provide 2+2 worry-free plans and 5+5 exclusive services for BYD Han car owners. In addition, BYD officials also said that based on 5G technology, Han EV will also launch a 5G version.

The appearance of BYD Han still adopts the design of family-style Dragon face, which is a perfect combination of form and function with daytime running lights and position lamp inspired by the shape of dragon whiskers. The front face of Han EV shows the typical elements of pure electric vehicles, and the closed grille is matched with the long and narrow headlight group to create a strong sense of the future. The front face of Han DM is more impactful, and the large-size lower grille shows the effect similar to lattice grille under the modification of a large number of chrome trim strips.

The high waistline on the side of the car runs through the whole body and perfectly blends with the slip-back line of the D-pillar, showing the tough atmosphere of sports in a coupe posture. Han EV has a length, width and height of 4980/1910/1495mm and a wheelbase of 2920mm, respectively. Han DM has a length, width and height of 4960/1910/1495mm and a wheelbase of 2920mm, respectively. Compared with Han EV, the body length is 20mm less. "EV" and "DM" signs are used at the lower left of the rear of the car to highlight its identity. The through taillight design is very scientific and technological, and at the same time, it effectively stretches the visual width, making the new car look lower from the back, giving people a sense of sight that is ready to go.

Chinese aesthetic concept and symmetrical design are integrated into the car, and the overall color tone is red and black. The red seat and the red decoration on the center console, steering wheel and door panel further highlight the sports attribute. Double-spoke flat-bottomed steering wheel and other designs add a sporty atmosphere to the interior; The electronic gear handle itself is more exquisite, and the function selection of the lever type is added in the key area, so that the driving mode can be selected. The configuration is equipped with a 12.3-inch LCD instrument panel, a 15.58-inch central control panel (embedded with DiLink 3.0 intelligent network connection system), an atmosphere light with "Long Lin" texture, APA full-scene automatic parking, OTA remote upgrade of the whole vehicle, a 12-way electric adjustable seat, a diamond stitch craft seat, a rear air outlet, wireless charging of 15W mobile phones, a rear USB, a 220V power supply, etc. The safety configuration is equipped with DiPilot intelligent driver assistance system, DiDAS. It is worth mentioning that APA automatic parking will be applied to BYD Han models for the first time.

Two super-long endurance models (middle and low models) of Han EV are equipped with front motors with maximum power of 222 HP and peak torque of 330 Nm, and their 0-100km/h acceleration time is 7.9 seconds; On the basis of the front motor, the four-wheel drive high-performance model (high-equipped model) adds a rear motor with a maximum power of 272 HP and a peak torque of 350 Nm, and its 0-100km/h acceleration time is 3.9 seconds. In terms of battery life, all three EV models adopt Ferrous lithium phosphate blade battery developed by BYD, with a battery capacity of 76.9kWh. The NEDC cruising range of the two long-life models is 605km, and the NEDC cruising range of the four-wheel drive high-performance model is 550km. It is worth mentioning that the high-performance version is also equipped with a Brembo high-performance braking system.

At present, there is only one model of Han DM, which is equipped with a hybrid system consisting of a 2.0T engine with a maximum power of 192 HP and a motor with a maximum power of 244 HP and a peak torque of 330 Nm. The combined maximum power is 436 HP and the peak torque is 650 Nm. The acceleration time of 0-100km/h is 4.7 seconds. In terms of battery life, the car is equipped with a ternary lithium battery with a battery capacity of 15.2kWh, and the NEDC cruising range of the car is 81km in pure electric mode.
