Shandong commercial newspaper reporter Sun
recently, Ji'nan launched the rail transit R1 line vehicles, traction, signal and other mechanical and electrical system equipment bidding, the popular point is that the Ji'nan track to start to buy the subway car, and the first car will be in 2017 12 Before the month arrives in Ji'nan, people will be able to see the "real object" of the Ji'nan subway by the end of next year. It is understood that the Ji'nan R1 line will buy 24 columns of B type 4 section of the metro vehicles, so the specific "B type 4 section of the group" is what it means, the reporter will read for everyone.
for
R1 underground
B type car
according to the bidding book, vehicle purchasing demand is B2 type The number of subway vehicles is 96 vehicles (4 marshalling * 24 columns). The main specifications are B2 models, and the localization rate is no less than 75%. In addition, the traction system procurement is specifically for the B2 metro vehicle traction system, the number is 96 vehicles (4 marshalling * 24 columns). The main specifications are also B2 models, with a localization rate of not less than 50%.
we can see that Ji'nan rail transit will choose B locomotive. So what does this "B type" mean? It is reported that the model of domestic rail traffic is divided into six types of A, B, C, D, Lb and cross seat monorail. Generally speaking, the four types of models are relatively popular, including A, B, C and D, of which A and B are defined as the subway models. Ji'nan rail transit R1 line project south of Changqing District pool East, north to Ma Zhuang West, the elevated line length of about 16.2km, the transition section is about 0.2km, the ground line is about 9.7km. It can be seen that the R1 line is mainly on the upper segment, but the vehicle has chosen the B type vehicle commonly used by the metro. "
" in general, the vehicle is carried out after the implementation of the line. At this time limit, the vehicle's outer wheel profile has already been fixed. In other words, in fact, the vehicle selection has been determined when the subway is opened. " People in the industry told reporters that Ji'nan used the common B type of the subway, mainly because of A, B and C, D models are essentially different, A, B model between 2.1 meters to 2.15 meters, C, D model is the shortest, also 2.1 meters, in order to pass the underground, so must choose the subway special model.
a car can carry about 1000 people
Ji'nan to the R1 line passenger flow forecast more conservative
words back, because there are underground segments, C, D model can not be selected, but A, B models are subway cars, can pass through the underground section, why did Ji'nan choose the B model? For the difference between the subway A and B models, the A type car is wider than the B type vehicle, and the A type vehicle is also longer. There is no cab car up to 22m, while B type vehicle length is 19m. So the A car has a larger floor area than the B model, so a A car can carry more passengers than a B car. The model A has a fixed number of 310 people, while the B model has 230-250 people. The A car has 5 pairs of doors per section, while the B model has only 4 pairs of doors per section.
that is to say, B cars can only carry 1000 people. "From the choice of vehicles, we can see Ji'nan's estimate of the R1 passenger flow. Generally, the subway is composed of 4 vehicles at least, most of which are 6 cars. The A type car can carry 310 people, four vehicles for 1240, six for 1860, 230-250 for the one B, 1000 for the four, and 1250 for the six. Ji'nan chooses B type 4 section vehicles, that is, the minimum carrying capacity of metro vehicles, so Ji'nan's estimate of R1 passenger flow is not too much. According to the industry analysis.
according to the requirements of the subway, the basic domestic
similar Qingdao subway or the bid by the four party locomotive
according to the bidding book, the domestic rate of the vehicle requirements is not less than 75%, and the traction requires that the localization rate is not less than 50%. "That is to say the Ji'nan subway should be made in China." People in the industry do so. It is reported that there are two companies in the country that are qualified to produce subway locomotives. One is China Central car, the other is Beijing vehicle. In China, 6 subsidiaries are qualified to produce Metro locomotives, which are Zhuzhou Electric Locomotive Research Institute, Qingdao tetragonal locomotive, Dalian locomotive, Tangshan locomotive, long guest stock and Nanjing Pu town.
"most of the subway will be won by the locomotive company near the territory, like the Nanjing subway in Nanjing, most of the vehicles in the town, so the Ji'nan subway is not an accident and should be the bid of the Qingdao Sifang locomotive, then the vehicle will probably be similar to the Qingdao subway, and it is estimated that the manufacturer will add Quancheng elements." People in the industry told reporters that if the Qingdao Quartet locomotive won the bid, the vehicle will probably be transported to Ji'nan many convenient, mainly the locomotive maintenance is also convenient, maintenance service can also be on the heel.
R1 will buy 24 subway
the first locomotive at the end of next year to Ji'nan
96 vehicles and the number of purchases, for 4 marshalling x 24. It is reported that the "traction" equipment will be assembled on the "vehicle", each carriage will be composed of a "vehicle" and a "traction" equipment. The popular explanation is that R1 has to buy 96 cars, and every 4 sections form a rail car body, that is to say, R1 has to buy 24 subway lines altogether.
it is reported that the first vehicle will arrive in Ji'nan in December 2017, and the subsequent train delivery plan will wait for the vehicle to pass the driving test and then carry out the quantity production. The R1 line is expected to open the trial operation in October 2019.
that is to say, the first car will arrive in Ji'nan before December 2017, so that at the end of next year, the citizens will be able to see the "real object" of the Ji'nan subway.
