Why are the subway and light rail in Dalian collectively called subway?

The construction of Dalian subway has fallen behind, and now the whole subway group is bidding for Shanghai subway, which requires the comparison of various indicators, such as the number of lines, kilometers, stations, and the maximum passenger flow of the morning and evening peak line network. It is helpful to bring the light rail in.

Moreover, Light Rail Line 3 does not belong to the bus group like 202, but originally belongs to the subway group.

Another important reason is that Dalian's own conditions are no longer allowed to build more, so it can't afford the money. For example, the Jin-Pu line has been built for many years because of financial problems, and it has not been opened to traffic. Whether it can continue to be built is still under discussion and is still in doubt. The construction of Line 4 has not started at all, and the promising line is Line 5, so it is necessary to pull the light rail in to make up the number and divide Line 3 into two lines: Line 3 and the extension line of Line 3. .........

There is no movement on Line 2 of the subway extension line. What happened?

All the same. You may not understand that the subway on Beijing Line 2 is above ground, but there are also underground subways in Hong Kong and Shanghai. Do you understand?

Whatever his name is. Bring convenience to the public. Call it anything. Dalian Metro 13 line used to be called 202 tram extension line. . .

Because there are few lines, add them together to make up the number, which sounds good.

When will Dalian Metro Line 6 be completed?

What's wrong with calling the subway? Don't call the subway. It is no problem to call the subway on the ground.

People who have no education and have never been to a big city don't think they will understand.

I wonder why you ask such a boring question. I wonder if I can visit Beijing, Hong Kong, Shenzhen and other cities. The world is a good thing, but you haven't seen it yet.
