Electric cars will not save cities. Let’s focus on an overhead railway and subway
Piotr Myszor - 28-02-2019
Half of the world's population lives in large agglomerations. Electromobility will save urban transport, but an e-car will not bring rescue. In that case, an e-bus or a tram? Or maybe an overhead railway?
Streets that can no longer be widened, tracks that are too large for a narrow centre - these are real brakes of urban transport. The goal would be public transport that does not use urban streets.
According to President of Sosnowiec Arkadiusz Checinski, individually used vehicles will still cause traffic. Cities need better public transport.
Today's agglomerations need solutions such as metro or Monorail - says Slawomir Nalewajka, president of Bombardier Transportation ZWUS Polska.
Rail transport specialists argue that electric cars will not save cities - they will eliminate one (exhaust fumes) and reduce another (noise) inconvenience. And that's not all...
- Individually used vehicles will still cause traffic. Cities need better public transport - said Arkadiusz Checinski, President of Sosnowiec, during a recent meeting held within the framework of Civil Dialogue, in which he participated together with Elzbieta Bienkowska, EU Commissioner, and Marcin Korolec, CEO of Electric Vehicles Promotion Foundation.
Communication without streets
In the modern city, mobility is a necessity and the main trend that is in conflict with the rational management of scarce space. Streets that can no longer be widened, tracks that are too large for a narrow centre - these are real brakes of urban transport.
The goal would be public transport that does not use urban streets. In this case, trams are not the solution, because their rails cover valuable surface, and the vehicles themselves are one of the elements of urban traffic that is prone to collisions. Metro or rail vehicles, with tracks placed on overpasses, seem to be a better solution.
The Bombardier company, with Polish branch in Katowice, in the Upper Silesian-Zaglebie Metropolis which controls Sosnowiec, strives to interest GZM, but also other Polish cities, with the system called Monorail.
Half of the world's population lives in large agglomerations. And this tendency is deepening. Soon most of Polish citizens will also live in metropolises and large cities.
- This entails the need to apply solutions that allow the transport of a large number of passengers in a short time - says Slawomir Nalewajka, president of Bombardier Transportation ZWUS Polska. Innovia Monorail 300 can run at a speed of up to 80 km/h and carry 40 thousand passengers per hour.
The wagons of this system move on a single concrete rail, thus covering less space than a traditional track. Of course, it takes place in the air, because on the ground we have only single-column supports of overpasses, and this takes up less space than tram tracks. The train does not stand on the rail, but in a way covers it, retaining much more stability than on a standard track.
Another advantage of this solution is the possibility of overcoming more inclined arcs - up to 46 degrees. All in all, it makes it easier to fit the route into the already existing town buildings. Trains run on pumped wheels with rubber tires, which reduces noise. This is another advantage from the perspective of noisy cities. There are also less vibrations caused by the moving train - both affecting the urban infrastructure and passengers' perception.
Tested in Asia
Last year, Bombardier signed a contract for the construction of two monorail lines in Bangkok - one is supposed to be 34.5 km long and the other 30.4 km. The lines will be occupied by 72 trains, each with 4 segments/wagons. They will carry 28 thousand passengers per hour and 400 thousand during the day in both directions. Bombardier did not boast about the amount of this contract, but the maintenance service contract signed for 20 years amounts to 245 million euros.
In Chinese Wuhu in 2020, Monorail will start moving on two lines with a length of 30.3 km and 16.5 km. 28 six-segment trains will be moving on the first one and 18 four-segment trains on the other. The value of this contract is 119 million euros.
Bombardier and Polish cities
- Today's agglomerations need solutions such as metro or Monorail. We can provide such solutions in the PPP formula or build, operate and draw charges from transported passengers - declares Nalewajka.
Rzeszow has been working on the projects of 7 km and 14 km lines for several years. The town's authorities declared that the biggest problem is the lack of provisions in Polish law recognizing this type of monorail solutions as public transport. It was included in the act on electromobility, giving a new word to the relevant article of the Act on public transport.
Another recipient could be the Upper Silesian-Zaglebie Metropolis. Bombardier sees the possibility of using a monorail for transport on the Chorzow-Katowice-Sosnowiec line, which is currently the most heavily laden in terms of individual transport, as well as a connection to the airport in Pyrzowice. The project feasibility study is being created.
