The reason for dismantling is absurd, as city managers believe that the overhead lines are not aesthetically pleasing enough.

We get that over here as well, quite a lot ... it's stupid since
1. it's infrastructure, so its primary goal is to be useful (see Japan's overhead electrical wiring infrastructure all over the streets which became quite a loved visual trademark of Japanese aesthetics).
2. it doesn't have to be visually displeasing, if it's well maintained (see Switzerland).
3. there are other things uglier in terms of infrastructure in the urban environment (such that urban highways which are noisy, dusty and polluting).
4. should aesthetics be more important than pollution?

Oh well, same narrow-minded politicians all over the world.

Currently, there are several brands of trolleybus operating in China:

I consulted a book about Chinese trolleybus and tram during the day, and the content reminded me that I had missed one model of trolleybus, as shown in the following picture. The introduction of this model in this book, translated into English, is:
BFC6129GBEVS1 is a test trolleybus model that uses the overhead lines for charging. Its pantograph (or call it "trolley") does not have a tension spring and relies entirely on cylinder control for lifting and lowering, so it is not suitable for running with pantograph lifting.


This also reminds me that just this year, Wuhan has just welcomed a brand new trolleybus. Because it is an experimental prototype, there is only one available, which model is WH6120GD. You can find information about it on the website below:

Definitely, Japan is the country with the best railway culture in the world, and it has a large group of railway enthusiasts, from the Prime Minister to elementary school students. Such a wide range of enthusiasts and clubs also make it easier for them to protect overhead lines.

In addition, many Chinese railway enthusiasts are also deeply influenced by Japanese railway culture, and their online names often come from Japanese railway lines.

On January 11th, the Ministry of Industry and Information Technology of the PRC announced the 391st batch of "Announcement on Road Motor Vehicle Production Enterprises and Products"（道路机动车辆生产企业及产品公告）. In this batch of new product announcements, the most eye-catching one is undoubtedly Yutong's release of a brand new appearance coach, which model is ZK6129H6QY. Although this is a brand new appearance, Chinese bus enthusiasts have expressed that this exterior design "draws inspiration" from Setra.

On average, the Ministry of Industry and Information Technology of the PRC will publish a batch of "announcements" of new products every month. Only products that have declared the announcement and passed the publicity period are allowed to be sold in China Mainland. Each bus manufacturer will publicly disclose their new products and some information in "announcements", so "checking announcements" is almost a "compulsory" course for every Chinese bus enthusiast.

China's vehicle product models consist of numbers and English letters, used to indicate the vehicle manufacturer, type, and important parameters. Since 1988, China has implemented the GB9417-88*[1] standard, which stipulates that models consist of enterprise name code, vehicle type code, main parameter code, and product serial number. Although this standard was abolished in 2001, due to its convenience and the lack of official new standards, the vast majority of manufacturers still use it to name their vehicles.

*[1]: GB is the pinyin acronym of "national standard" (cn: 国家标准, cn Pinyin: Guojia Biaozhun) in Chinese, which means that the standard is applicable to Chinese Mainland (excluding Hong Kong, Macao and Taiwan).

Next, I will take the most common China made bus in Romania, the GTZ6129BEVR, as an example to explain how this standard works.

1. The enterprise name code is located in the first part of the model, consisting of two to three English letters. This code is usually derived from the manufacturer's Chinese Pinyin abbreviation.

In the GTZ6129BEVR, GTZ stands for Enterprise Name Code.

The manufacturer of GTZ6129BEVR is Zonson Smart Auto Co., Ltd. (cn: 中兴智能汽车有限公司). It acquired Zhuhai Granton Bus Co., Ltd. (cn: 珠海市广通客车有限公司, cn Pinyin: Zhuhai Shi Guangtong Keche Youxian Gongsi) in 2016, and the latter's production qualifications were also retained, which means the former (Zonson Smart Auto) can continue to use the latter(Zhuhai Granton Bus)'s company name code. It is obvious that the two letters "GT" in the enterprise name code are derived from the initials of the Chinese Pinyin "Guangtong". As for the letter Z, I guess it may come from the Chinese word for "manufacturing" (cn: 制造, cn Pinyin: zhizao).

2. Next is the vehicle type code, which only has one number. The numbers and their corresponding vehicle types are as follows.
 1 Truck
 2 Off road vehicles
 3 Dump trucks
 4 Tractors
 5 Specialized vehicles
 6 Bus and Coach
 7 Sedans
 8 Unused (Null)
 9 Semi trailers and specialized semi trailers

It is worth mentioning that China does not classify trolleybus as "Bus and Coach", so some manufacturers use the 5 to refer to them, some manufacturers continue to use 6, while some manufacturers do not follow this standard at all. The first two are the mainstream in recent years, such as Yutong ZK5105A, Zhongtong LCK5180A, and Yuancheng DNC6129BEVGS1 etc.

3. According to the standard, the main parameter for buses in China is length. Here, two digits are used to represent the parameter. When the length of the vehicle is greater than 10m, the vehicle length is rounded to the nearest integer and used as the main parameter code. While the length of the vehicle is less than 10m, the vehicle length is accurate to one decimal place and multiplied by 10 as the main parameter code.

The length of GTZ6129BEVR is 12080mm, so naturally, we should write 12 after the number 6 (representing the Bus & Coach).

You may ask why the model in other cities in Romania is still GTZ6129 instead of GTZ6119, as the length of this model is only 10800mm.

This is a good question. As I said earlier, this standard is only applicable to Chinese Mainland. So outside Chinese Mainland, this model is just a combination of numbers and letters. You can consider them as models similar to ADL Enviro 500.

On the other hand, we all know that Bucharest was the first city to purchase the GTZ6129, so the manufacturer was the first to obtain the sales qualification (certification, homologation and so on) for the GTZ6129 in Europe. So when manufacturers want to sell buses of other lengths in the future, they do not apply for new sales qualifications under the name of "new model" for the sake of saving money, but only expand the parameters based on the existing model.

4. Next is the product serial number, starting from here, the standards vary by enterprise. For Granton GTZ6129BEVR, the number 9 refers to this bus model. Can other numbers refer to this model? Perhaps, but it depends on how their corporate standards are established.

5. The last part is the enterprise's self custom code. Although there are various enterprise standards, they are not completely without rules to follow. In some models, "BEV" is usually used to refer to "battery electric vehicle". In addition to Granton, Yutong also frequently uses this rule. Other common codes include SHEV (Series hybrid electric vehicle), PHEV (Parallel hybrid electric vehicle), FCEV (Fuel cell electric vehicle, usually use hydrogen) and so on.

Thanks for decoding the chinese model number system.

we all know that Bucharest was the first city to purchase the GTZ6129

Unfortunately, no. Before Bucharest, we already have nearly 200 same buses delivered in the country.

Now we have delivered at least 533 GTZ6129 e-buses, also 36 GTZ6609, 23 GTZ6709 and 43 GTZ6859 e-buses.

Thank you for your correction. I always thought that the first buyer to purchase Granton was the STB.
So, may I ask if anyone else has purchased GTZ6129 before Bucharest?

There are quite a lot of cities that bought them beforehand. The first one was Suceava, where buses were delivered in 2020. Afterwards, there was a nationwide tender for buses, where we had GTZ6129BEVR again, as well as other local tenders; cities like Constanța, Târgu Mureș, Tulcea, Craiova, Iași or Piatra Neamț are some of the most important where Granton buses were delivered, through the Romanian-Turkish importer BMC.

You can find all of the buses here, on our forum, mostly in the "Regions of Romania" (Regiunile României) subsection. We generally noted them as "ZTE Granton", due to standardization concerns and easiness to search for within our search queries.

The full lists of ebuses and cities you can find on Transphoto where I keep the lists updated.
